Parts Required:

Valvetronic motor gasket, valvetronic motor

Hot Tip:

Work with a cool engine.

Performance Gain:

Removal for access to other components and remedy oil leaks from Valvetronic motor gasket

Complementary Modification:

Replace seal for motor

The Valvetronic motor is used on BMW E90 models with a normally-aspirated engine. It is responsible for actuating an eccentric shaft that adjusts intake valve lift. The motor itself is pretty reliable and does not fail too often. However, you will have to remove it for other engine repairs and the gasket that seals the mounting surface of the Valvetronic motor fails and leaks oil. When repairs are performed on the Valvetronic assembly, the limit stops have to be relearned. You will need access to a BMW scan tool to do this procedure. The limit stops are the mechanical limit stop, end to end of rotation of the eccentric shaft. The DME (digital motor electronics) records these stops via the eccentric shaft sensor to determine mechanical adjustment limits of the eccentric shaft. With that said, when removing the motor to replace the gasket you are not changing the mechanical position of any Valvetrnoic assembly components, a relearn is not always needed. Now use this with caution and when in doubt, perform the relearn. Do your research and check with up to date repair information before beginning.

In this article, I'll go over the steps involved with replacing the Valvetronic motor and Valvetronic motor gasket on BMW E90 models. Be sure to work with a cool engine.

Remove engine covers. See our tech article on engine cover removing.

Disconnect negative battery cable. See our tech article on battery replacing notes.

Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches. 

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Do not work on your vehicle if you feel the task is beyond your ability. 

Vehicle models change and evolve as they grow older, so the vehicle shown in our illustrations may vary slightly from yours. If something seems different, let us know and share your info to help other users. Questions or want to add to the article? Leave a comment below.

When installing new gasket, be sure black stripe is facing up.
Figure 19

When installing new gasket, be sure black stripe is facing up. (green arrow).

Then press into valve cover until fully seated.
Figure 20

Then press into valve cover until fully seated. Install Valvetronic motor in reverse order of removing. Use a 4mm Allen bit to rotate motor clockwise while installing into cylinder head. Once flush with cylinder head, install fasteners and tighten. Remember, if you removed aluminum fasteners, replace them each time they are removed. Be sure wiring harness is routed as it was before and engine covers are properly aligned. Turn key to ON position for 30 seconds, then OFF, then ON again for 30 seconds before starting vehicle.

When repairs are performed on the Valvetronic assembly the limit stops have to be relearned.
Figure 21

When repairs are performed on the Valvetronic assembly the limit stops have to be relearned. You will need access to a BMW scan tool to do this procedure. The limit stops are the mechanical limit stop, end to end of rotation of the eccentric shaft. The DME (digital motor electronics) records these stops via the eccentric shaft sensor to determine mechanical adjustment limits of the eccentric shaft.

Frank Comments: I Finally got my codes 2A6A VVT-Power supply bank2and 2A6B Emergency vvt

what suggestions do you have my car is in limp mode right at start up and i lear the codes and it comes back without starting the car, just by turning the key it goes to reduuced engine power limp mode
November 18, 2016
  Followup from the Pelican Staff: If the Valvetronic motor fuse and power supply are Ok, the motor may be faulty. - Nick at Pelican Parts  
Max Comments: Hello, i own a bmw e90 03-2007 with fault code 2A67C8. Reading your guide i understand that first of all it's better to check if it's a fuse problem, could you indicate me where is the fuse box and which fuse i have to check? Second question, how can i understand that the fault it's not related to the eccentric shaft position sensor? Thank you for your support.
November 17, 2016
  Followup from the Pelican Staff: I don’t have that info.




I would grab a repair manual. It will have the wiring and fuse locations.

Give our parts specialists a call at 1-888-280-7799. - Nick at Pelican Parts
 
Frank Comments: HI i have two codes p1060 and p1062 Points to the vavletronic motor bank 2p1060
when i start my car is goes into limp mode right away.
reduced engine power
what would be your best opinon on this matter
November 14, 2016
  Followup from the Pelican Staff: You need to check if the Valvetronic motors are getting consistent power. It possible the Integrated power module (ISM) is faulty. - Nick at Pelican Parts  
Perspective Comments: 2006 325i. What can be causing the valvetronic motor to get very hot shortly after starting the engine. I don't have a BMW scan tool, only an OBD reader.
October 30, 2016
  Followup from the Pelican Staff: How hot? It may be normal engine temp. - Nick at Pelican Parts  
Teddy W Comments: Hello, I own a 2006 e90 320i getting code 2e8b 2eb8 2a67 2a6b when scan on the limp mode. Could this be battery issue? or the valvetronic motor issue? The odd thing is that the engine will work fine when you start the car from cold but goes into limp mode when you stop and start in short time like drive to shop buy things in shop for 5-10mins then come back to car and start car the limp mode active but when start and let the engine cool down like few hours and start the car works normal. Any suggestion? Thanks

October 16, 2016
  Followup from the Pelican Staff: I would assume the issue is more likely the valvetronic motor than the battery. - Nick at Pelican Parts  
kenny Comments: hello i have replaced oil separator on my e90 325i n52engine and still the problem not solved. cylinder 1,2and3 misfire and the injectors have oil only those 3 cylinders. what might be the problem?
October 15, 2016
  Followup from the Pelican Staff: COuld be a piston ring problem. I would check spark, fuel and compression on all cylinders. - Nick at Pelican Parts  
Kenny Comments: Hi my 325i e90 is missfire on cylinder1,2nd 3. I have removed intake manifold and I fine oil inside.injectors 1,2and 3 also have oil. No power on the car.what might be the problem? I found code 29cc,2aa8. Please help.thanks
October 14, 2016
  Followup from the Pelican Staff: If the crankcase breather is faulty is could be allowing oil in the cylinders, fouling the plugs.

I would check spark, fuel and compression on all cylinders. - Nick at Pelican Parts
 
dermotw Comments: Hi,

On a BMW 318i, I am seeing 2A67 valvetronic internal fault 10859, after having swapped the ECU for a replacement which was updated with the old ECU's data. Can you suggest why?? Thanks in advance! -D
October 7, 2016
  Followup from the Pelican Staff: Possible faulty replacement ecu. - Nick at Pelican Parts  
KBolsh Comments: Hello,
I'm getting codes
2A61 Valvetronic Adaptation and
2A6B Valvetronic Power Limitation Servomotor
The limp home engine light comes on, however I notice no drop in power at all, performance seems unaffected.
Can you advise what these specific codes mean, and what could cause the fault ?
October 5, 2016
  Followup from the Pelican Staff: There is either an issue with the sensor measuring the eccentric movement or a movement issue. I would start by checking actual verse desired values using a BMW scan tool. - Nick at Pelican Parts  
gieri002 Comments: My bimmer suddenly went into limp home mode when accelerating onto an onramp yesterday. The codes shown by my scantool are:

2a3f valvetronic actuator motor: power supply
2a9f camshaft sensor exhaust synchronization

As a simple check I swapped the intake/exhaust camshaft sensors but the code didn't switch from the exhaust to intake side so I'm guessing that code is somehow related to the other. I've done some reading on your forums and have read that the 2a3f code is commonly displayed incorrectly by cheaper scan tools. The last 7 digits of my VIN are KV05847 can you tell me if this is true in this case?

I've reviewed a vvt wiring diagram and have visually traced vvt wires+fuses from the battery to the motor, all LOOK fine but I have not busted out a multi meter yet. If this code is real, I'm guessing this should be my next step? Any other suggestions? What voltages should I be seeing?
September 28, 2016
  Followup from the Pelican Staff: if the motor fuse is fine, the motor may be faulty. usually with a motor code it is one of the two. - Nick at Pelican Parts  
Kev Comments: I nick. I have a 2007 328i and its a throwing a 2a43 and a couple misfire code which I'm assuming are stemming from the 2a44 code. There's also two mixture codes, 29e0, 29e1. I've done some research on the eccentric sensor and the motor. I've checked, and the sensor connector is bone dry, no oil in it at all. So, my question is, do u think it's the motor itself and Not the sensor?? Do the motors go out and not the sensors??? Your info would be greatly appreciated.
September 11, 2016
  Followup from the Pelican Staff: The motors can fail, but more than likely you get additional faults, (motor circuit). With fuel trim faults, it leads me to think the issue may be with engine timing. Is the timing chain noisy? - Nick at Pelican Parts  
ahmadarifai Comments: Hello,
i have e92 N52 engine, with only one code 002A38 valvetronic drive slow or open circuit.

could this be the shaft sensor or the valvetronic actuator?

thank you for your help.
September 4, 2016
  Followup from the Pelican Staff: Could be either. I would try the sensor first. They fail more frequently. - Nick at Pelican Parts  
HeaddiesJP Comments: are you referring to the eccentric sensor? If so, damn wasted my money on the valvetronic part I bought
August 24, 2016
  Followup from the Pelican Staff: Yes, the eccentric sensor. - Nick at Pelican Parts  
jack stinkicat Comments: 2011 bmw 328i sedan n51 xdrive
August 24, 2016
  Followup from the Pelican Staff: Most likely a faulty eccentric shaft sensor. http://www.pelicanparts.com/BMW/techarticles/BMW-3-Series-E90/FUEL-Eccentric_Shaft_Position_Sensor_Replacing/FUEL-Eccentric_Shaft_Position_Sensor_Replacing.htm - Nick at Pelican Parts  
HeaddiesJP Comments: Hello,

Have a 2009 E90 with about 60,000 miles. I'm getting code P1030 or from an aftermarket BMW scanner I bought code 2A38 Valvetronic, servomotor: sluggish movement or open. I bought the valvetronic actuator from BMW but i'm nervous from reading other blogs that the eccentric sensor which is $500+ just for the part might also be the problem. If it was the eccentric sensor, it would draw a code for it right?

When i got this code for the valvetronic, I don't experience anything on the driving performance. I only experience an issue when I'm idling and have the AC on for about 5 min, the half yellow check engine light appears and the motor jolts. After this, I turn the car off, it goes away.

Hoping it's just the valvetronic actuator I bought. and Hoping that I dont' need a BMW Tool to relearn it when I replace it.
August 22, 2016
  Followup from the Pelican Staff: Thanks for supplying both the generic and BMW faults, that makes answering more efficient. The fault you have is for motor movement, so the sensor can be the cause. I would check if the sensor electrical connector has oil in it. This is a sign of a faulty sensor. - Nick at Pelican Parts  
jack stinkicat Comments: hi I Am getting codes p2fa3 p2a32
2011 328i n51 sulev no real symptoms only service engine soon light and maybe takes a little longer to start
August 22, 2016
  Followup from the Pelican Staff: What vehicle are you working one? - Nick at Pelican Parts  
Vinkuch Comments: Following: Those codes are for the throttle housing. You may have a wiring harness issue. It is common on BMWs to have an issue with the connector at the throttle housing

What do you suggest? buying new connectors?
August 22, 2016
  Followup from the Pelican Staff: I suggest testing the connector. Visually inspect it for loose terminals. You use a pin fit test kit or monitor voltage at the DME while wiggling the connector. if voltage fluctuates, replace the connector and wiring harness leading up to it. - Nick at Pelican Parts  
Vinkuch Comments: Hello Nick, i changed the throttle body, and it keeps on doing the same. is my VVT causing this?

Throwing the following codes:
Throttle valve adaptation value
Throttle Valve
Throttle valve potentiometer 1
Valvetronic, adjustment range

This codes showed up after a throttle body change

Vinkuch Comments: E90 2006 325i has rough start, idle not stable and below 750, throws 2f4a, 2cfb, 2d09, 2ba2, 2e9f,2cf9, 2a39

When driving at times it stalls, or loosing power completely and at times it will want to pull even on brakes

What could be the possible cause and solution. Thanks
August 19, 2016
  Followup from the Pelican Staff: You may have an issue with the throttle housing. I would check throttle operation using a BMW scan tool. A few of the codes didn't show up for me, if you have descriptions I may be able to offer more insight. - Nick at Pelican Parts

Jim Comments: I replaced the valve cover gasket on my 2006 325i and did not remove the valvetronic motor properly. I removed it without cranking it into a natural position and did not crank it out of the valve cover. It just popped out . I reinstalled it and motor will not run I have spark and fuel. Did i cause damage to engine? Is there a way to reinstall it properly now? Or can this be fixed with just a BMW diagnostic tool?
July 9, 2016
  Followup from the Pelican Staff: If the eccentric shaft slammed down the limit stop can break. Try turning the key on without starting the engine and letting it sit for a moment.

Next i would check the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.
- Nick at Pelican Parts
 
Rob Comments: replaced valve cover on my bmw 328i 2007. after everything is complete all electrical plug in. THere is a lock symbol display on the dash. im unable to start the car because key will not push in place. are you able to give any advice on this issue rob
July 8, 2016
  Followup from the Pelican Staff: Sounds like the vehicle doesn't recognize the key or the key slot failed. I would check the vehicle for fault codes, also try a second key. - Nick at Pelican Parts  
Rob Comments: I have a 2007 328i BMW that has an oil leak at the valve cover. I purchased a new cover from the dealer I am familiar with disconnecting everything except Valvetronic motor. I don't have a scan tool to reset
Can I remove and replace this without a scan tool and how
July 3, 2016
  Followup from the Pelican Staff: Most times you can get away without using a scan tool. The article describes the process. - Nick at Pelican Parts  
Eddie Comments: Hello, I have a 2007 BMW 328i that has received a Valve Cover Gasket repalcement about a few months ago. Noticed that the ecentric shaft sensor gasket was leaking as well and should probably be changed as well, also starter was replaced about 3 months but now the car will not crank. I hit the start ignition hear a click but car will not crank. OBD shows P105B and P1056 .. woudl these cause the vehicle not to crank ? Thanks
June 21, 2016
  Followup from the Pelican Staff: Unlikely. I would think it is a coincidence. Check if the starter has good voltage and is receiving the signal to the solenoid to start. - Nick at Pelican Parts  
kv308wrench Comments: What a good technical support group the is at Pelican Parts just like someone was right beside you from start to finish I have been in the German auto repair field for 35 years and these instructions are the best I have ever seen

zz Comments: Firts off all, I want to thank you for all the great work and time, to respond and give answers to all our people,and it is highly appresiated.
I have a bmw 2006 e60 n52 525i fault codes.p1030 and after i drive off above 20 kmph i get p0015. So both p1030 and then p0015. Do you think ist the valvetronic motor that sets both the the codes.
May 26, 2016
  Followup from the Pelican Staff: It could be either the sensor or the motor. Since the first code is performance code.- Nick at Pelican Parts  
Latza Comments: Hello, BMW 320i 110 kilowatts seems little engine performance. Sometimes the engine power is increased. No error message. It could be a faulty Valvetronic? thank you
May 5, 2016
  Followup from the Pelican Staff: Not without fault codes.

Could be an issue with the fuel pump. I would perform a fuel delivery system test. Check fuel pressure, volume and quality.

apson Comments: Error 2A70 after deleting back again. Adaptation motor in INPA running because I can hear attitude. The ISTA motor does not respond.
April 21, 2016
  Followup from the Pelican Staff: ISTA motor? ISTA is a repair information / diagnostic system.

You likely have a faulty Valvetronic motor or worn camshaft parts. - Nick at Pelican Parts
 
apson Comments: Comments: Hello, I own a 2006 E87 118i. Diagnostic tool shows only 2A70 error. I didn't anything suspicious other than that this is my first beemer, though. Could this be an eccentric shaft sensor, Valvetronic motor, or something completely different? Thanks!

Hi I have this same foult any sugestions?
April 20, 2016
  Followup from the Pelican Staff: The issue could be a faulty Valvetronic motor. Before replacing it, see if adapting the limit stops helps. - Nick at Pelican Parts

elias Comments: Is motor wil cost plus how much or can you gave me the number to call
March 16, 2016
  Followup from the Pelican Staff: I am not sure what the repair will cost in your area. Call a few shops and ask for a quote. It is also a good idea to have them confirm what the issue is.

Fish Comments: Hello, I red on TIS software the procedure that is exactly the same except for the installation after gasket replacement. You wrote figure 20 that we have to rotate clockwise while installing into cylinder head but, as you can see in the linked picture, Bmw tells to rotate counterclockwise. I don't know if is a problem but i prefer to ask you because i don't want to make critical mistake.
Last question: Is it essential to make the relearn via software? Is not sufficient the waiting procedure that you describe in figure 20? I have to replace just the gasket. Thank you very much.
March 15, 2016
  Followup from the Pelican Staff: The relearn is essential. Info I have says counterclockwise to remove, reverse to install motor.

The arrow in your image shows rotation clockwise, but the statement in coutnerclockwise. That does not look like ISTA, so it isn't current information. I can;t comment on it's validity. - Nick at Pelican Parts

Mike. Comments: Hello,

2011 N55 E92 E262881, with 86k miles. I just cleaned the valves with solvent and a brush due to engine malfunction. Valves are spickety span, but I'm now getting codes 2DCE and 2E0F. I'm guessing the valvetronic motor. Any experienced ideas? Thank you for the tutorials, you have saved me hours and lots of dollars over the past year! Thank you, Mike.

  Followup from the Pelican Staff: Your fault can be due to a VANOS issue. I would check if the VANOS system is running at the desired value. Going by memory, there may be a repair kit available for the VANOS bolt, spring. Give our parts specialists a call at 1-888-280-7799. They can figure out what part or repair kit you need.

Oscar Comments: I have a 2007 328i e90 N52N. When changing new spark plugs, I didnt disconnect the battery and put my wrench on a jump terminal near the fuse box and VVT motor and ignition coils. There were sparks and the wrench flew out. When starting the car there was engine problem warning and service light was on. There is now loss of power, late throttle response, and a ticking coming near fuel injectors. I connected OBD2 scanner and read code P1056, problem with low volts in VVT power bank 1. What was damaged and needs replacement?
January 15, 2016
  Followup from the Pelican Staff: I don't know what was damaged. You will have to do some testing. Use a BMW scan tool to run a self test on the VVT motor. It may have been shorted or the fuse has blown. - Nick at Pelican Parts  
ben Comments: I have a 2008 328i and have codes 2A3F and 2A77. The car does not run good at all. the codes are for the valvetronic actuator motor power supply. It could be a faulty motor but i want to check the fuses or relays before I get a new motor. Can you help?

Thomas Comments: 3719 valvetronic, supply voltage: short circuit to ground.
Do you know what that code is, and how to repair it?

December 24, 2015
  Followup from the Pelican Staff: This could be a fault in the wiring harness for the valvetronic motor. i would check the wiring from the motor to the DME. - Nick at Pelican Parts  
Nick Comments: Thanks for the comment Nick! In regards to removing and installing the same VVT Motor, how crucial is it to turn the resistance, is this a necessary removal and installation procedure to engage the motor before doing a soft start?
December 23, 2015
  Followup from the Pelican Staff: It is a good idea to install and remove using the tool to drive it in and out. Before starting, turn the key on, don;t start the engine. This allows the motor to find it's place. - Nick at Pelican Parts  
Nick Comments: What happen if you install the motor incorrectly, will the engine break? What fault code should one expect? Also, you mentioned resistance when turning the motor, turn it clockwise first, then counter clockwise when removing it, correct? Can you also clarify the resistance, when to stop turning it.
December 22, 2015
  Followup from the Pelican Staff: You could have poor engine operation and fault codes. If you force the motor or remove it incorrectly, you could break the Valvetronic gear or lever. - Nick at Pelican Parts  
jack Comments: hi. i drive a 335i coupe E92 2007model. the problem is when at times i am driving at a constant speed, then attempt a sudden acceleration, i get a sign and reading "engine power loss. maximum power not possible. continue drive "
but funny is the car still performs normal. i reported the issue at first service but nothing was done about it.
the trick is sometimes it never shows at all for days then boom , its at it again. what could be the cause of this
December 2, 2015
  Followup from the Pelican Staff: This is due to a fault in the system for engine management. I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.

Will Comments: Hi, I've got an E90 320i. I've got codes 2AA8 constant and 30C1 occasionally. The low oil pressure light comes on when the engine is cold however when it warms up I switch the engine off and on and the light doesn't come on again until the engine cools. Any idea what this might be?
November 25, 2015
  Followup from the Pelican Staff: These are faults with the variable volume oil pump. You could have oil pressure issues. I would not drive until you confirm engine oil pressure is normal. The oil pump may be faulty. - Nick at Pelican Parts

  Followup from the Pelican Staff: Check the valve cover, top corners. - Nick at Pelican Parts  
Vnw Comments: I have an issue with my E90 320i. It's a 2006, purchased 2 months ago. As soon as I bought it, it indicated that I need to change the valvetronic motor, which I did. After a couple of days, the car gave a shudder in the morning every time I start with a miss. At one instant, when I started to reverse, it stalled completely. After that, the check engine light came on and when I took it to the garage, it appeared that there was water in the ECU / DME. They cleaned and sealed it back again however they said it will need to get replaced at some point because the ECU has been submerged 1/3rd in water and could have caused damage.
My issue is now again the car is stalling and it does not have the full power. The check engine light is also constantly on. When I took it to the garage, it showed in the scanner the foll;
valvetronic plausibility sporadic fluctuations
valvetronic power limitation servomotor

Is it an issue with the valvetronic motor? Does that need to get replaced again? Can it be that there is an incompatibility with the new valvetronic motor that was fixed?

Or is it an issue with the DME due to water damage? Pls help. Thanks.
November 16, 2015
  Followup from the Pelican Staff: I would assume the DME is faulty from the water intrusion issue. Start there. - Nick at Pelican Parts  
Ade Comments: Thanks for your comment Nick , i already did a compression test on all the cylinders and they all came up with 150 readings. 150 was consistent throughout the 4 cylinders. do you think the vvt motor could be the problem?
November 11, 2015
  Followup from the Pelican Staff: Yes it could be. With the high current codes, you either have a faulty motor or a jammed eccentric shaft. - Nick at Pelican Parts  
Ade Comments: Hi Nick , I drive a 2006 BMW 318i e90, car runs rough and rpm jumps in idle and sometimes the car stalls, scanned it and it came up cylinder 1 and 4misfire.

Took it again for scan and this time it came up with cylinder 1&2 misfire,vvt party error 750km&850km,vvt excessive current 790km and vet minimum lift exceeded 850km. Got the car 3months ago.i don't know what to do now. Can you please help. Thanks
November 11, 2015
  Followup from the Pelican Staff: I would check spark, fuel and compression on all cylinders. My guess is the problem will be found in compression, with the valve lift faults. - Nick at Pelican Parts  
Razz Comments: Hi I have a 2005 e90 320i what has started to go into limp mode intermittently
Doesn't depend on engine temperature just intermittent, could drive 30miles and car would not be in limp modeengine hot turn it off then back on and car would be in limp mode engine hot
And exact same when cold
Come out 1 morning, engine light on but car driving ok and some other mornings it would be in limp mode
Got these 3 faults...
P1006 guiding sensor
P1014 reference sensor parity

I have changed the eccentric shaft sensor and car is still the exact same!
Someone please help shed some light in this

  Followup from the Pelican Staff: Possible problem with the valvetronic motor or the power feed to the motor. - Nick at Pelican Parts  
Matt B Comments: I noticed a few folks chiming off about this seal leaking oil. You'll probably share the embarrassing smoke-at-stop-light effect after making any hard left turns, and I also was here trying to solve that problem.

I replaced the seal itself with a new part to no avail, and both the incoming and outgoing parts looked completely undamaged, because they were. Still, new seal would leak onto coils/plugs, hard left turn pushed oil onto hot exhaust housings, and I was hot boxing the wrong part of my car, and worrying those around me of an impending fire dept intervention.

I took it down again and added the highest temp gasket maker I could find. Applied very very lightly and very carefully not to drop any into the workings behind. Let it dry per instructions and I haven't seen a drop of oil out of it since. No more strange looks at stoplights. Unlike Derick Zoolander, I now turn left without fear. And you can too!

Can I put some voltage o it? if so how many volts ?
September 11, 2015
  Followup from the Pelican Staff: Only with a BMW scan tool using the test plan inside the tool. - Nick at Pelican Parts  
Rick Comments: Nick what software and scan tool do you recommend to relearn the limit stop procedure?.
I replaced the battery after it was flat, now I cannot start the car, the scan tool is giving me VVT Code
September 2, 2015
  Followup from the Pelican Staff: You will need an advanced BMW scan tool. Something like Autologic or Pass-thru. - Nick at Pelican Parts  
Dave Comments: How does the BMW scan tool actually work to relearn the limit stops?
August 25, 2015

Marcus1973 Comments: So I did a little experiment today with the no start problem.The code 281e seems to be the culprit do I turned the car on today without trying to start it and left it for 15-20 minutes and then tried to start it and it fired up running very rough and stalled out about 10 times but then eventually ran smooth and only 1 other code the 27 cb cam control bank 2 exhaust. What is the reason for the code 281e ? I have replaced the entire intake complete and had the same effect same codes. What is the deal with the 15-20 min wait time before starting, could it be a immobilized or something key related it doesn't show any code for it though?
August 15, 2015
  Followup from the Pelican Staff: The manifold actuators could be at fault, however the no start doesn't seem to line up.

I would need to know what is, preventing it from starting to offer more help. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and fuel pressure, volume, quality and engine compression. - Nick at Pelican Parts
 
marcus Comments: I just got a 02 745i from auction with 146000miles on it.

I am having a hard time starting this car but will start after 15-20 min.The main code its showing that I think is the problem is variable intake output stage servomotor, car wont start if this code is showing , once gone it will run rough for a few minutes about 5-10 then run great.Other codes showing are 27bb , 27bc ,2737,5140,273d,2866 but I can relearn these over and over and doesnt seem to help any .Is there a test I can do with the intake out of the car on the servomotor and where does it get its information from ? The previous owner looks to have been into the dme wires testing things,Oh I also got a different complete intake from a friend and it had the same exact symptoms as before.I have a registered new battery in the car , new oil filter and plugs , verified fuel pressure of 50lbs , im probably forgetting something but thats it for now.

What could cause all of these codes..bad coils? eccentric shaft sensor?
August 12, 2015
  Followup from the Pelican Staff: Start with one code, then see what comes back after the repair. The misfire codes and sluggish driving tells me you should be looking for a misfire first. I would check spark, fuel and compression on all cylinders. Which could be related to the mixture faults, maybe vacuum leak. - Nick at Pelican Parts  
Sonny Comments: Can bad vvt motor cause no compression on number one cylinder or eccentric cam shaft sensor.

Brian U. Comments: Hey Nick, Thanks for the reply. I narrowed those codes down to the camshaft position sensors and eventually figured out I HAD the exhaust and intake sensors backwards on both sides of the engine. Power is back and all is running great after replacing the exhaust sensors as they blew out while they were in the wrong placement. For anyone doing valve cover gaskets beware it's very easy to swap the sensors by accident!

Taimur Comments: Hi Nick,

I was advised by BMW to replace the VVT Motor and eccentric shaft sensor which was leaking oil. I noted that the wiring harness was wicking a small amount of oil to the DME. The DME however seems to be okay, i.e. there are no errors pertaining to that specifically. Is there any way to clean out the wiring harness? Will stopping the leak at the eccentric shaft sensor preclude further damage to the DME, or are there any other precautions I should take, such as periodically cleaning out the wiring harness? Replacing the harness and DME would be far too costly.
July 7, 2015
  Followup from the Pelican Staff: If oil made it to the DME, the only fix is to replace the harness. I would do it before it contaminates the DME. - Nick at Pelican Parts  
Brian. U Comments: After replacing the Valve Covers on my 04' 545i, I experienced a lack of power in low RPM's as well as a slightly sporadic idle and engine valve clatter when coming to idle down to 500rpm and back up to around 800.

The 4 OBD codes I read are Timing Over Advanced, bank 1 exhaust & intake, as well as bank 2 exhaust and intake. I'm under the impression I messed up the timing on both banks when reinstalling the valvetronic motors? Would you suggest I remove using your procedure and reinstall? Or would I take the chance of causing it not to start? Please help as the lack of power is killing me, it's a V8!
June 25, 2015
  Followup from the Pelican Staff: I would start by relearning the valvetronic motor limits using your scan tool. That may solve it. - Nick at Pelican Parts  
sebrina Comments: Nick- so no more smoke and gasket has perfect seal. the knocking is top on the side of the vavletronic motor. No it dint do this before, just the warming up tick. Not this really bad knocking. I cant figure it out because I didn't touch anything inside. There is also no SES light at all. I did change the spark plugs, but I went back through and rechecked the coil. Im really at a loss here. Someone did mention the VANOS solinoids. Could leaning these help?
June 18, 2015
  Followup from the Pelican Staff: If the knocking is coming from the motor, then I would assume an issue with the Valvetronic shaft or gear. Remove the motor and inspect the drive for damage or signs or uneven wear. - Nick at Pelican Parts

- Nick at Pelican Parts
 
Matty Comments: Hi guys, great write up, could you tell me why you need to rotate the valvetronic motor clockwise until resistance, but then rotate it counterclockwise when removing? it seems to me by rotating clockwise the motor will meet its limit, but then you say to undo that, therefore rendering the clockwise adjustment until resistance a bit pointless? thanks guys.
June 17, 2015
  Followup from the Pelican Staff: These are BMW's procedural steps, I do not question them.

the point is to unscrew the motor without slamming the Valvetronic camshaft to it's stop and install it so the motor is flush and not putting force against Valvetronic camshaft.- Nick at Pelican Parts
 
Sebrina Comments: All back together but now it is ticking/ knocking loudly from the top left of engine. And smoking. Should I do the correct steps to take off the Valvetronic motor and then put it back on? Or did I cause damage already?
June 17, 2015
  Followup from the Pelican Staff: Smoking and ticking, top left as in the front of the cylinder head, left side? Did it do this before the repair? I can't see how the Valvetronic motor would cause smoking. I would check if the valve cover gasket and breather valve are installed correctly. - Nick at Pelican Parts  
sebrina Comments: OK, will do. Why do you think I was able to take it out without doing that? I am pretty sure there was no resistance.
June 16, 2015
  Followup from the Pelican Staff: Sometimes they will come out without help. When removing, I always support the motor from behind, and extract using an Allen. This prevents the possibility of the VAlvetronic shaft drive from returning to a stop too hard. - Nick at Pelican Parts  
sebrina Comments: I am in the process of reinstalling after a valve cover gasket change and EVS change and I too did not have to use and allen wrench to get my motor out. I have not gotten to the reinstall of it, but am wondering what the appropriate steps would be to get it back in right. It had absolutely no resistance when I took it out. So when I go put it in, should I be using the allen to turn it in any way?
June 16, 2015
  Followup from the Pelican Staff: Once the cover is all back together, thread the motor back in using an Allen bit. Once in and assembled, turn the key On but do not start the engine, do this twice. Then start the engine. - Nick at Pelican Parts  
IK Comments: Hi, I did a valve cover gasket replacement on my 2008 528i, and did not take the appropriate step to remove the Valvetronic motor. I just popped it out and forced it back in without using the allen to screw it back in, and a relearn process was never done. I went to start the engine and hear that ticking noise, and the idle is extremely unstable. Did I mess up the engine? what can I do to fix this problem?
June 13, 2015
  Followup from the Pelican Staff: Something may have been damaged if the valvetronic shaft returned too hard. I would start by checking the vehicle for fault codes. If needed, relearn the Valvetronic stops. - Nick at Pelican Parts

April 17, 2015
  Followup from the Pelican Staff: I would guess you left something unplugged or something is plugged in the wrong place.

When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and fuel pressure, volume, quality and engine compression. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.
- Nick at Pelican Parts
 
Scooba Comments: Yes I believe so. Looks it is seated all the way. Is there anyway it could be done wrong? Should I re-do the installation?
April 1, 2015
  Followup from the Pelican Staff: If the seal wasn't seated, it would hold the motor out away from the valve cover, fouling the limit stop adjustment. May need to double check the install, then reset the motor limits using a BMW scan tool.- Nick at Pelican Parts  
l. arnold Comments: Replaced valvetronic motors. Had bmw do the limit relearn. Drove it 20 miles and the same two codes came back plus now I also have 29cc,29d1,29d3,29d2 along with the original 2a6b and 2a6d. I originally noticed oil on the eccentric cam sensor connectors but no codes for them So I left those alone. Can these sensors throw codes 2a6b and 2a6d or is there something else I'm missing. Wouldn't bmw have had problems doing the valvetronic reset if there was actually something wrong with the system. Thanks for your help.
April 1, 2015
  Followup from the Pelican Staff: Not usually, as those codes are for the valvetronic motor circuits. If you have oil in the harness, replace the sensors. Otherwise the oil will wick to the DME and ruin it. - Nick at Pelican Parts  
scooba Comments: i checked the motor has power, is there a possibility the vvt motor has gone bad? the car started fine before i changed the gaskets. i put everything back together how it should be.i also got code p105b along with the p1056. thanks again.

I am left with Fault code 2B70 VARIABLE INTAKE Manifold SYSTEM after changing the battery and adjusting the valvetronic motor, replace the Variable intake manifold drive motor. I intend to remove the Air variable Intake Manifold, P/N 11617537882, for detail inspection and possible pressure test to verify I don’t have a crack that can’t be see on virtual inspection. I read on your write-up that there should not be oil contamination Intake manifold. I also read on the blog that there is a process to wash the Variable intake manifold with a mixture of oil and gasoline. Is this true, and cant you give me the mixture ratio, my intention is to reinstall the old variable intake manifold if no crack or leak is noted. I will like to clean any contamination in the intake manifold, and use pressurized air to dry the flapper vanes before installation. Your input will be appreciated.
March 27, 2015
  Followup from the Pelican Staff: Do not use gasoline and oil mixture to wash it. Use warm soapy water.

The code could be related to a pressure fault, meaning manifold pressure not as expected. If this is the case, it could be worn valvetrain components. - Nick at Pelican Parts

andrew Comments: Hi there i've had eml light come on few weeks ago with 2a67 fault which wouldnt clear. the garage changed the valvetronic motor, sensor and rocker gasket cover, but a day later the fault returned and back into limp mode. the garage says the valvetronic motor bmw secondhand is fine but they cant fix the fault. Could it be a blown fuse or a wiring issue?
March 17, 2015

Mwishlist Comments: Hello, I replaced my valve cover for a bad crankcase breather valve issue and when removing the valvetronic motor it "popped" out when I took out the last screw. I followed the procedures for reinstallation but now I'm getting random misfires and the following codes.
2a31
2a32
2a47
2ef7
could this be the valvetronic motor needs the relearn procedure or do you think the eccentric sensor has also gone bad? I almost replaced it while I was in there but of course I didn't. Although the seal was good and there was no oil in it. 2008 328i 85k miles. Also, I did the key relearn procedure but to no avail.
March 14, 2015
  Followup from the Pelican Staff: Check if the seal for the valvetronic motor is fully seated. I have seen a few people not press it in all the way, causing these faults.

If it is OK, check valvetronic adjustment and end stop using a BMW scan tool. Relearn if needed. - Nick at Pelican Parts
 
mejim707 Comments: Hi, I've noticed that the valvetronic motor has a leaking seal. So tonight I removed the two upper Valvetronic motor E8 fasteners but did not attempt to remove the motor. Something stopped me and I said "I don't even know what this does", and when in doubt don't do it! So I put the screws back in. Can you tell me, after removing these screws, do I need to do the relearn if the motor was not removed? I will be replacing the seal but I just don't have the time right now to do it. Thanks a lot for the excellent tutorial. This is going in my bookmarks!

i recently purchased this vehicle and I am trying to fix the defect as a do it your self mechanic. I am having the engine display Engine safe mode program indication, it can drive smoothly , initially I scanned for fault and had fault code 2B71 VARIABLE INTAKE CONTROL and 2B70 Variable suction system . I performed detail virtual inspection of the intake manifold, no leak discovered. I noticed substantial fluid leak at the Brake boaster vacuum pump coming from the lower engine case. I replaced the Brake boaster vacuum pump p/n 11667635657. After the replacement of the Brake boaster vacuum pump, I too the vehicle for a test drive, the same Engine safe mode program indication came back, but this time the fault code change to 2A69 VALVETRONIC, SERVO MOTOR : POWER SUPPLY, and 2A6A valvetronic servo motor 2 power supply" using a Peake research R5/FCX3 code tool. Can you give me any maintenance tip to use in troubleshooting this.

Ed Comments: Can't remove valvetronic motor on 2006 325i.....what am I missing? I've rotated the allen wrench fitting in the back and taken out the two E-torx bolts, one on each side. There is a little wiggle now but the motor won't come close to coming out, even with the allen fitting all the way CCW. I don't see an E-torx bolt underneath, just two lower bolts, one on each side, that look like regular torx but have something sticking out in the middle, like a security feature, and around the top they say "DO NOT OPEN." I'm guessing they only hold up a lower support but the support is not affixed to the motor. Nonetheless I can't get the motor to budge much. May have to abandon this valve cover replacement job.

twinky64 Comments: 2007 328xi E90 with 105k miles Automatic Trans.

After I changed the Valvetronic gasket, I experienced a rough idle. Driving felt normal without hesitation. Power seemed normal without any losses nor loss of throttle sensitivity. Coming to a stop proved to be rough and engine flirts with stalling. I re-installed my old spark plugs just to rule out the new spark plugs. I still get the same rough idle with normal driving performance and problems coming to a stop. The codes I get are P0303, P0305, P0300, P1415, and P0171.

Read forums and most responses point to vacuum leak. I checked all hoses and PCV valve ? located on top of Valve Cover near the firewall. Everything looks great! I checked the Valvetronic Gasket again, and I noticed that one side was not fully seated by 0.5mm!!! With nothing to lose, I tightened it to full seated position and started the car. Performs very well as intended without hesitations or troubles coming to a stop. All codes cleared as a result.

Lessons Learned:
1. The new Valvetronic Gasket is slightly bowed. Ensure mounting the gasket is fully seated at fastener locations ref. fig 17 - Torx 30 Fasteners.

2. The seemingly small vacuum leak caused by a 0.5mm-1.0mm gap on one side of the Valvetronic Gasket caused misfires. This can lead someone toward replacing ignition related components and troubleshooting MAF sensor.

3. When performing a Valvetronic gasket change without swapping Valvetronic motors, the need to re-learn via BMW Scan Tool did not seem necessary my experience.

Thank you! All is well and back to normal.

twinky64 Comments: 2007 328xi e90
Another update. I rotated the hex insert behind the Valvetronic motor. Im getting a rough idle but better than before. Before, I was experiencing a rough idle where my engine would flirt with stall and the ecu keeps itself alive by blipping gas. Since Ive rotated the Valvetronic motor until a resistance is felt, the engine will come to rest with "Service Engine Soon" followed by a P1415 reading on my code reader. I did not change the Valvetronic motor. Only changed the gasket.
November 16, 2014
  Followup from the Pelican Staff: I believe that is a fuel trim fault code, could be from a calculated air issue due to the valvetronic fault.

Do not rotate the hex unless you are removing or installing the motor. At this point, I would have the valvetronic limits relearned, may fix your issue. - Nick at Pelican Parts
 
twinky64 Comments: 2007 328xi e90

Replaced Valvetronic gasket and spark plugs. Also wiped off VC withshop towel. I never touched or unplugged the Eccentric Shaft Sensor. Fresh spark plugs and all ignition coils attached and plugged into.

Symptoms:
Rough idle after reaching operating temperatures. Blipping throttle works fine. Start up is fine. Im getting Service Engine Soon light. Prior to working on Valvetronic gasket change, vehicle performed perfectly. What would explain my symptom? Admittedly, I did not unplug my battery.

Thank you for your help

twinky64 Comments: Hello Nick,
2007 328xi e90 with 105k miles

I am performing a valvetronic gasket change. Upon removing the ignition coils direct adjacent to the valvetronic motor fig 9, there is oil pooled inside the ignition coil and spark plug socket. I used shop towels to soak up oil from these sockets/chambers. NOTE: remaining 4 ignition coils andi nsides spark plug sockets were dry.
Dirty film of oil was found along the top of the valve cover and around the sides pretty much everywhere on the VC.
Also, oil was pooled around the ignition coils in proximity to the valvetronic motor fig 7.

Could the pooling of oil inside the two adjacent spark plug sockets be a symptom of the failed Valvetronic gasket? Or Valve Cover Gasket?

Would a failed Valvetronic gasket explain the coating of oil found over the entire VC?

Where is the leak coming from wrt a failed Valvetronic gasket? Would it be wise to use oil resistant gasket sealant when installing a new Valvetronic gasket? If so, where and how much to use?

Thank you very much
November 16, 2014
  Followup from the Pelican Staff: If there is oil, as in fig 16, it is from a leaking valvetronic gasket. Install the gasket dry, no additional sealant. - Nick at Pelican Parts

Changed the chain and the chain guide and value gasket. car drove like crap and the cam-shift sensor came on followed by 2A67 and 2A6B . Realised the tensioner as flat changed it. Car drove and sounded better. 2A67 and 2A6B came back on. changed the vvt motor. one week later 2A67 and 2A6B is back on. Can it be the relay?

  Followup from the Pelican Staff: You could have a faulty Valvetronic motor. I would start there. - Nick at Pelican Parts  
Car luz Comments: I change the gasket but I forgot to rotate the motor with the Allen other than that I follow all your procedures and is working fine do you think I got lucky or its ok to drive like that ? Thanks
August 16, 2014
  Followup from the Pelican Staff: If then engine is running well and there are no fault codes, you should be OK. - Nick at Pelican Parts  
Car luz Comments: when you say turn the key on for 30 seconds you are saying push the the on button for 30 seconds with out pressing the break?

  Followup from the Pelican Staff: Correct, allow the DME to power up, but do not start the engine. - Nick at Pelican Parts  
Mr Saw Comments: My BMW 320i, 2005 model consumes about 4 litres of engine oil, with milege of about 4,000 kms run.Notice white smokes emits from tail pipe when accelerator is pressed to 4,000 rpm.in addition, the valvetronic motors lights up as malfunction. Are they related or is this a two separate problem.
July 29, 2014
  Followup from the Pelican Staff: White smoke is likely coolant. I would pressure test the cooling system. If the system will not hold pressure and there are no external leaks the head gasket may be faulty.
If faulty, this could also be the oil consumption issue. - Nick at Pelican Parts
 
Johns Comments: I just replace ECCENTRIC SHAFT SENSOR, I didn't rotate the motor back when installing it, I try to relean it with modis ultra scan tool but the relearn keep stoping, and engine light is on for mass air flow system.. Do u think the mass air flow code got something I done
July 21, 2014
  Followup from the Pelican Staff: What is the code number and last seven of the vehicle VIN? COuld be due to shaft position. I am not sure if a MODIS can do that task. An adavnced BMW scan tool, such as Autologic is needed. - Nick at Pelican Parts  
TROY325i Comments: Hi! Is it normal for the vvt motor to pop out when last bolt is taken out?
June 24, 2014
  Followup from the Pelican Staff: Yes, that is you why you have to support it while you remove the last bolt, then unscrew it from the eccentric shaft. - Nick at Pelican Parts  
kyle Comments: Thanks Nick but i'm still a bit confused. What does rotating the valvtronic motor CW do in figure 11 and what is happening when rotating CCW in figure 15. Since i didnt rotate my VVT motor what rotation should i be performing in figure 20?
June 6, 2014
  Followup from the Pelican Staff: Rotating moves the Valvetronic camshaft into a neutral position and winding it back in engages the motor to the Valvetronic camshaft drive. - Nick at Pelican Parts  
Kyle Comments: I removed my valvetronic motor without rotating at all. The motor popped out when i took out the last bolt. Can i reinstall and do the key on adaptation. If so what steps must i take to reinstall the motor?
June 5, 2014
  Followup from the Pelican Staff: FOllow the re-installation steps in this tech article. See fig 20 and 21. - Nick at Pelican Parts  
Marion325i Comments: Followup from earlier post. I put it all back together and it worked great. Thanks for the help and the great tech support.

Marion325i Comments: Hello, Thanks for the great write up. I found this after I had gotten started on my repair. I made a mistake with the valvetronic removal and am wondering what to do. I did turn the shaft CW as instructed but was concerned about the "slight resistance" part so I'm not sure I turned it far enough or too far. I'd say roughly 1.5 turns. Problem 1.

Problem 2 is that I neglected to turn it CCW while removing it didn't read the full instruction and I believe I felt something move as it came out never a good feeling.

Now I'm wondering how to reinstall? I have a Bavtechnic enthusiast kit so I think I can reset it. Ideas??

Big Thanks!
May 18, 2014
  Followup from the Pelican Staff: You may have felt the eccentric shaft move when the motor was extracted. As long as it didn't slam, you should be OK. I would go ahead with the reassemble, perform the relearn and check for fault codes. - Nick at Pelican Parts  
Shaboz Comments: After replacing an engine of E60, 2005 model, the car wound't start. And after scanning the engine it came out to be the valvetronic, could this be the problem?
May 9, 2014
  Followup from the Pelican Staff: COuld be if there is an issue with the system. I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and pressure fuel, volume and quality. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.

WBAW Comments: Bavarian Technic has the capability to reset the valvtronic adaptation. They claim its the same thing but I'm not convinced. your thoughts?
April 26, 2014
  Followup from the Pelican Staff: You may have to take their word for it. I have no experience with that tool. - Nick at Pelican Parts  
WBAW Comments: Where can I get this mythical BMW Scan Tool?
April 23, 2014
  Followup from the Pelican Staff: You can use the ISTA tool from BMW or Autologic. - Nick at Pelican Parts  
James A Comments: I swapped my head out recently and am using the valvetronic motor from my old head, will I need to re learn it? And if so is this something that can be done with PA Soft?

Thanks James
April 15, 2014
  Followup from the Pelican Staff: Yes, if major parts are replaced, I would relearn the end positions. - Nick at Pelican Parts  
Steve Comments: If i am just replacing the gasket, will the motor have to relearn the limit stops? this is the only DIY guide that mentions that step.
April 11, 2014
  Followup from the Pelican Staff: I have done it both ways, with and without the relearn. If you haven't made changes to the mechanical components, you may not require the relearn. Try turning the key ON for a minute before starting the engine. Then turn key OFF, then start engine. - Nick at Pelican Parts  
john Comments: hi i have a 99 318i it drives perfect except for when i slow down about to stop i having a harsh down shift two times before it come to a full stop
April 7, 2014
  Followup from the Pelican Staff: First check the transmission fluid level to be sure it is correct. Then check the transmission ECM for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.
- Nick at Pelican Parts
 
Elliot Comments: Hi Nick, I replaced cover gasket before I saw your instructions. Valvetronic motor sprang out of its place and I didn't turn it anywhere. I installed it back in and didn't turn it either. Now car shows Check Engine Soon after I recycled it a few times. I have no tool to read a code. Is there anything I can do for DMA to re-learn the limits.
March 31, 2014
  Followup from the Pelican Staff: No. I would start by checking the DME for fault codes. It may not be what you think.
- Nick at Pelican Parts
 
Jose Comments: Thank you Nick first thing tomorrow calling for an diagnostic app

Jose Comments: Hi there I have a 328i 2011 with 14k I was driving today I park the car when i try to start the car on a later time the car star shaking the engine light come on.
I went to the near auto zone he plug the scanner in the car it come on with P1030 after 30 minutes of driving the car i turn off the car and turn it back on engine light gone.
Should i take it to the dealer can you please help.
March 29, 2014
  Followup from the Pelican Staff: The code is:
P1030 is the error code.

Valvetronic (VVT) Actuator Monitoring Position Control, Control Deviation (Bank 1)

I would get the vehicle to the dealer. - Nick at Pelican Parts
 
ks123 Comments: Will using the wrong oil cause the valvetronic servomotor to fail? I just bought a used 2007 328i and 2 weeks after the dealer changed the oil the valvetronic servomototor and eccentric shaft are failing.
February 27, 2014
  Followup from the Pelican Staff: The motor is not lubricated with engine oil, so now. Valvetronic parts do wear over time like all other components, I would think they are worn from normal use. - Nick at Pelican Parts  
Chauf Comments: My e90 on a 55 plate is using oil, blue smoke after it has been ticking over for about 5 to 10 mins, it had to go on to a bmw machine for a fault on seat belt problem,and it came up with valve tropic fault, could this affect oil usage ?
February 26, 2014
  Followup from the Pelican Staff: Valvetronis is the adjustable valve lift system. I would assume if it is smoking a different part of the engine has a fault. Inspect the crankcase breather to begin with. i would however address the Valvetronic fault ASAP. - Nick at Pelican Parts  
Brammers Comments: Hi Nick my E91 crawled to BMW garage. Mechanic said failed valvetronic motor and replaced it. Still wouldn't run so mechanic said DME ruined by faulty motor. Still wouldn't run and mechanic now saying faulty eccentric shaft. If it does turn out to be the ecc shaft, could I argue that the motor and the DME probably weren't faulty after all - or does a faulty e-shaft ruin the other components? Thank you
February 16, 2014
  Followup from the Pelican Staff: hard to say. In my area, you have the right to request the old parts. I would ask for them to review the diagnosis and explain why the previous parts did not repair it and more are needed. If it seems they are having trouble, a second opinion is best. - Nick at Pelican Parts  
Marcus Comments: Hi,

I have a 2008bmw 320i, a few days back I felt a loss in power while accelerating uphill. The car wouldnt accelerate like it used to and then the error light came on. Error code 2A67. Earlier I had some issues with some oil leak. My mechanic says that the valvetronic motor and the sensor has to be replaced. Please advice.
February 10, 2014
  Followup from the Pelican Staff: 2A67is a fault code for the Valvetronic system. if your mechanic has diagnosed, I would go with the recommended repairs. - Nick at Pelican Parts  
Mike Comments: Hi,

Is this procedure the same for a 2006 530? My valvetronic keeps falling off the sprocket and then the car wont start. When I remove it and reset the sprocket and install the VVT back in it starts up just fine. Does my valvetronic need to relearn the limits via the BMW scan tool. Only code that comes up is P1024 which is in relation to the VVT. Any advice would be appreciated.
February 7, 2014
  Followup from the Pelican Staff: It is similar. However, it sounds like you have a mechanical problem. I would use a BMW scan tool to check desired and actual Valvetronic camshaft position. - Nick at Pelican Parts  
Lesegos Comments: Hi, I have 325i 2006 e90 model the car cannot start at first I could drive but stops as if no power had it checked in by diagnostic machine, it showed vanos intake, but the mechanic got me a long list of parts, electromagnet, adjuster out impulse send,adjust unit,collar screw profile gasket. I am now more confused please help.
February 7, 2014
  Followup from the Pelican Staff: If it has been diagnosed, I would go with the mechanic's suggestion. He likely gave you a list of all the parts that will be replaced during the repair. - Nick at Pelican Parts  
tebza Comments: after replacing valvetronic motor and dash light still stays on can i drive my car like that before i take it to bmw to relearn it. can i drive long distance to reach bmw workshop
February 1, 2014
  Followup from the Pelican Staff: I would not drive the vehicle until you have the light remedied. - Nick at Pelican Parts  
tebza Comments: hi please assist me,after replacing valvetronic motor do i have to relean it through a computer?
January 28, 2014
  Followup from the Pelican Staff: Yes, if the motor is new I would suggest setting the end stops using a BMW scan tool. - Nick at Pelican Parts  
bimm Comments: Hi! :- these are my problems on my e90 320i and I believe it concerns the valvetronic. Every time the car starts, the idle runs rough. Then I tried to diagnose it with a generic scan tool, there's no error on it. But when I try to clear/erase thru the scan tool, then the idle runs perfect. This happens every time I start the car. For sometimes it won't start, and I have to short circuit the valvetronic motor in order to move for the car to start again and clear no errors again? Hope you guys could help me on these. Thanks so much.
December 19, 2013
  Followup from the Pelican Staff: This could be related to a fault in a few places. I would have the vehicle scanned with a BMW scan tool. As there will likely be fault codes stored, these codes will direct you to the problem area. to - Nick at Pelican Parts  
Charlie Comments: Hello, I have an 07 328i and will just be replacing the gasket. I do not have access to a BMW scan tool. What symptoms will occur if the relearn needs to be completed?
December 18, 2013
  Followup from the Pelican Staff: If you are just replacing the gasket, you should be Ok without adjusting the Valvetronic values when done. - Nick at Pelican Parts  
nufcmosebimmermad Comments: Hi nick thanks again, mechanic has changed those vanos solenoids no joy unfortunately, done bmw diagnoses same fault code show as above part but it gives possible causes so he's now on cause nom# 3 which is a valve and seals need replacing inside/around the the crank shaft? He says he needs a specific tool too remove this and too hold some other bits and pieces together so it don't all drop, sorry for the vague description I was still shaking from the suggestion that it may have too go too bmw too be replaced ::: have you any clues as too what part he's on about and rough price I'm fairly sure he said the crank shaft need too come out and I think it was some kind of allignment tool, any second opinion at this stage is gratefully recieved so thanks for your input nick
October 24, 2013
  Followup from the Pelican Staff: They did have problems with the camshaft, and cam carriers wearing causing low oil pressure to the vanos solenoids, there are a lot of special tool involved in replacing any of those parts. I would recommend that you only lets someone that has all of the special tools needed do the job. Otherwise something could get damaged.
- Nick at Pelican Parts
 
nufcmosebimmermad Comments: Hi nick thankyou for your reply, would A manufacturers diagnosis machine be able too detect any codes that a normal garages machine would not detect ? Also could any of the serviced parts be at fault??? I have been searching forums a few people have said too check valvetronic value settings, could these of been changed with a mechanics resetting device after service?? Kind regards lee
October 23, 2013
  Followup from the Pelican Staff: The factory equipment will always give you more info, the valvetronic minimum valve lift can be changed but it sounds to me like you are having a problem with the vanos solenoids.
- Nick at Pelican Parts
 
nufcmosebimmermad Comments: hi im having issues with my e90 325i 2006,recently had it fully serviced an hour after coming from the garage it began too shudder at traffic lights loose revs then stall sounded like noises from the exhaust,garage had it back and fault code said oil pressure low.mechanic changed 2 solenoids in the exhaust not sure where?£300 lighter out of garage and 2 hours later the problem has returned with the engine management light illuminated i could not return the car until the following morning,at which stage the check light had gone off and the garage informed me that there wernt any codes being shown so after a quick drive mechanic gave the all clear.2 days later the problem has appeared again seems too be stalling whilst driving now idle speed is around 500 rpm and problem seems to appear once engine is warmed.been looking through bmw forums and a few comments point towards valvetronic motor do you think this could be a plausable explanation,or do you have any other suggestions as too the the underlined problem,would be appreciated sounds like a big can of worms and alot of man hours too solve something that should be simple
October 23, 2013
  Followup from the Pelican Staff: It could be a valvetronic problem, or a problem with the vanos system. There should be some faults stored if the car is not running correctly. Have the vehicle scanned with a factory scan tool to see what faults are stored in the DME.

kumar Comments: Alao when putting back in valvetronic motor what way do i need to turn the allen key?
May 25, 2013
  Followup from the Pelican Staff: Rotating the motor using an Allen bit engages the motor into the Valvetronic eccentric camshaft. - Nick at Pelican Parts  
kumar Comments: Hello, I have a 2006 bmw 330xi and my valvetronic gasket is a lot different than this one. It has a similar shape but also has a little circular piece of rubber. I dont know where it goes and I cant get it to sit into the engine.
May 25, 2013
  Followup from the Pelican Staff: Look closely at the valve cover and see if the gasket is still installed. Looking at a parts diagram, your gasket should be similar to the one in our tech article.

There are two types of valve covers, metal and plastic. The gaskets are different, the procedures are similar. - Nick at Pelican Parts
