Parts Required:

VANOS solenoid, O-ring, VANOS solenoid fastener

Hot Tip:

Work with a cool engine.

Performance Gain:

Remedy fault codes and restore engine performance

Complementary Modification:

Replace in pairs

The BMW E90 engine utilizes two VANOS (variable camshaft timing) solenoids. One for the intake camshaft and one for the exhaust camshaft, mounted to the front of cylinder head. They are responsible for direct oil flow to the VANOS actuator and can become restricted over time on high mileage engines. You can clean or replace the solenoids quite easily if needed. My suggestion is if you have determined you need a VANOS solenoid by cleaning or swapping side to side, replace both solenoids. They are fairly economical and you're always better off replacing a degrading part. The sealing O-ring for the VANOS solenoid can also leak. If you have an oil leak down the front of cylinder head, inspect solenoid area for fresh oil.

Inspecting VANOS solenoids once removed: Check VANOS solenoid for cleanliness and or debris. Clean both solenoids and reinstall. If the fault code for camshaft position sensor goes away or swaps position from intake to exhaust (or vice versa), the fault code is being caused by the VANOS solenoid. Replace the solenoid that the code followed. Here are fault codes you may have if a VANOS solenoid is causing your problem, 2A9A Cam sensor, inlet signal invalid for synchronization, 2A98 (P0016) Crankshaft intake correlation value outside ref range, 2A82 intake VANOS jammed mechanically, 2A9B exhaust camshaft sensor signal invalid for synchronization, 2A99 (P0017) Crankshaft position sensor and exhaust camshaft, correlation value outside reference range, 2A87 exhaust VANOS jammed mechanically.

In this article, I'll go over the steps involved with replacing the VANOS solenoids on BMW E90 models. Be sure to work with a cool engine. Replacing the VANOS solenoids is similar for both. I will highlight how to replace and clean the exhaust VANOS solenoid.

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

Working at front of radiator support, remove two T20 Torx fasteners from the intake duct.
Figure 1

Working at front of radiator support, remove two T20 Torx fasteners from the intake duct. (green arrows)

Working at intake air duct connection on air filter housing, using a small flathead screwdriver, release retaining tabs on each side and pull duct off.
Figure 2

Working at intake air duct connection on air filter housing, using a small flathead screwdriver, release retaining tabs on each side and pull duct off. Normally-aspirated engine shown. For turbocharged engines, the duct on the radiator support unscrews the same as the previous step, the duct for the air filter housing is also removed the same way, the air filter housing is in a different spot. Follow duct and release tabs to remove duct.

Then, pull intake duct out of radiator support and remove from vehicle.

The VANOS solenoids are located at the front of the cylinder head.
Figure 4

The VANOS solenoids are located at the front of the cylinder head. The intake VANOS solenoid is mounted on the top front of the cylinder head (yellow arrow) and the exhaust VANOS solenoid is mounted on the bottom front of the cylinder head (green arrow).

Working at intake VANOS solenoid, disconnect electrical connector by pressing wire release tab and pulling off.

Remove VANOS solenoid 10mm fastener.
Figure 6

Remove VANOS solenoid 10mm fastener. (green arrow) Do not reuse this fastener. Throw it away once removed and replace with a new one.

Using a flathead screwdriver, gently lever against metal bracket on VANOS solenoid to extract from cylinder head.
Figure 7

Using a flathead screwdriver, gently lever against metal bracket on VANOS solenoid to extract from cylinder head. Be very careful not to damage solenoid or cylinder head when doing this.

Pull VANOS solenoid sensor out of cylinder head.
Figure 8

Pull VANOS solenoid sensor out of cylinder head. Have a rag nearby in case some oil drips out of cylinder head when sensor is removed.

The VANOS solenoid O-ring usually stays in the cylinder head when solenoid is removed.
Figure 9

The VANOS solenoid O-ring usually stays in the cylinder head when solenoid is removed. Be sure to pull it out before reinstalling solenoid. (green arrow)

Clean VANOS solenoid and be sure it is free of debris.
Figure 10

Clean VANOS solenoid and be sure it is free of debris. The best way to clean it is to lightly blow it out with compressed air.

Install VANOS solenoid in reverse order of removing.
Figure 11

Install VANOS solenoid in reverse order of removing. Replace the fastener and O-ring every time sensor is removed from cylinder head. Slide O-ring (green arrow) onto solenoid until it is against spacer (yellow arrow). Lubricate O-ring with clean engine oil to facilitate installation.

Mr. D Comments: I have a 2007 328I E36. It was idling rough, engine light is on, it will drive but stall out when car comes to a stop. codes P0016 P006, MULTIPLE. replaced coil pack for cyclinder 6, spark plugs, and camshaft position sensor. starts up fine now engine light still on, still stalls out. please help. is it the intake solenoid?
June 26, 2015
  Followup from the Pelican Staff: Sounds like a possible engine timing issue. I would check vanos actuator function using a BMW scan tool and mechanical engine timing. - Nick at Pelican Parts  
CTFRuNnEr Comments: Good afternoon,

I have been chasing this issue for a bit now I have noticed some random stalls and idle a bit erratic at startup and the occasional longer start cranks. I have a bavarian technic and pulled the following codes.

2A80:
2A80 inlet-Vanos variable cam control test, input signal
Error will cause a warning light
Error is not currently present
Test conditions have been completed
Timeout

2A99:
2A99 crank shaft - outlet camshaft, correlation
Error will cause a warning light
Error is not currently present
Test conditions have been completed
Short circuit or signal interruption

I am pretty sure the cam position sensor is bad as moving it from intake side to exhaust side caused the error code to move to the exhaust side. The other things I have been hearing is that VANOS can cause false failure codes for cam or crank position sensorsand I noticed that I have a VANOS code but I am not 100% sure what that code is. Is it like its not detecting the solenoid at all? I have swapped the VANOS solenoids with no changes in the codes for the VANOS. Other than a few stalls once and a while and some rough starts the car still seems to run fine but I have noticed some decrease in gas mileage. Was looking to see if there was any advice thanks.

The car is a 2007 328XI n52 engine.
June 23, 2015
  Followup from the Pelican Staff: Your problem is similar to another user who just asked for assistance. My response it similar for both issues.

Sounds like a possible engine timing issue. I would check vanos actuator function using a BMW scan tool and mechanical engine timing. - Nick at Pelican Parts
 
adam Comments: The fuel trim is fine.
That is the weird part.
I am Fluctuating between 67-75 PSI.
June 1, 2015
  Followup from the Pelican Staff: Sounds off. Should hold steady. See this article: http://www.pelicanparts.com/BMW/techarticles/BMW-3-Series-E90/FUEL-Fuel_Pump_Testing/FUEL-Fuel_Pump_Testing.htm - Nick at Pelican Parts  
Adam Comments: Hello,
I'm having a very odd problem with my 2007 BMW 335i E90 with an N54.
At idle, I get a very slight stumble/shake every 5-6 seconds.It's NOT a very heavy stumble/shake and I just had a complete tune up done; coils, plugs, turbos and injectors etc.
I have no service lights on and no engine codes at all.
The car is not telling the computer anything.
I had it hooked up to a snap on OBD reader, checked the
spark plugs, coils and everything. Everything seems fine.
The problem does not effect performance or engine power
but I am now starting to feel this very slight stumble/cough/ shake when driving at around 30-45 mph ONLY SOMETIMES which I did not feel before. I had an idea that maybe the High pressure fuel pump is going bad but I have had no major symptoms of it. It turns on and cranks fine, I have no engine performance loss, Fuel trims are correct at idle and PSI Fuel Pressure reading is Fluctuating between 67-75 PSIIt was on Empty when I read the Fuel Pressure so I don't know if that matters.
I wish I was getting a code so I could figure this out.
I know it's not a major problem right now but I'd rather know. Has anyone had this issue before? Is it Fuel pump related or does anyone know what could be causing this?
May 31, 2015
  Followup from the Pelican Staff: With no fault code it can be tough to narrow down.

If you suspect fuel pump, I would start by checking the fuel trim numbers at idle and when the problem is present driving. Check if the fuel system is rich or lean when the problem is present. - Nick at Pelican Parts
 
Mario Vasquez Comments: 2007 328i E90 automatic, 73k miles.

Car runs fine, but noticed a slight performance drop when accelerating quickly. Out of a whim, I scanned and got error code with 2A87 Exhaust VANOS, jammed mechanically and erased the error to see if it would appear again. I still get error code 2A87 Exhaust VANOS, mechanism. Car runs fine, but is this worth replacing the solenoids to be safe?
May 29, 2015
  Followup from the Pelican Staff: A jamming code could be the actuator. I would try swapping the solenoid from one bank to the other. If the problem follows, replace the solenoid. - Nick at Pelican Parts  
SusieQueue Comments: 2008 E91 N52 SportWagon .... can a weak battery reading 12.32 V cause a Vanos code? I don't have the specifics code but I know it is Vanos related. Thanks: Susie
May 20, 2015
  Followup from the Pelican Staff: Is that open circuit battery voltage?

If so, no it would not cause a VANOS code. - Nick at Pelican Parts
 
RAL Comments: Hi, I have a 2005 E60 with N52 engine, and had some troubles lately. When the engine was cold, the car had some rough idle, some sort of hiccups between 1700-2000 revs in the 2ng gear, when accelerating and really bad fuel economy. I also could feel the car not powerful enough. No faults checked it at 2 different garages. Meanwhile everything was cleaned, new service done, new plugs, filters, etc. Also fitted 2 brand new solenoids. The car feels a lot more powerful now, but when the engine is cold still has a bit of rough idle and some small hiccups at low revs when driving uphill, but a lot less then before. I understood from on of my mechanics the car needed a "reset" after the new solenoids were installed, the only thing I didn't do. Should I expect this reset to improve something? or should I look for something else like the Vanos unit?
May 9, 2015
  Followup from the Pelican Staff: Is the check engine light on? Sounds like an engine misfire. I would check spark, fuel and compression on all cylinders. if not a misfire, you want to check fuel trim to see if it is skewed in one direction. This will give an indication of engine performance and what lacks if anything.

Ed Comments: Hi Guys,

Its Ed here again - I noticed something strange I went to the main dealer with regards to the errors I got - after diagnostics they told me needs further investigation either timing or vanos fault just as you guys said.

However I've checked the errors on my reader and they now report bank 2 and not bank 1.

2718 nockenwellengeber einlass bank 2
2761 vanos maximal-anschlag einlass bank 2

Is there any possibility these could be due to faulty solenoid s?

Otherwise worse case how much could a vanos problem cost or a timing issue cost?

Thanks
Ed
April 30, 2015
  Followup from the Pelican Staff: Not sure on the cost to repair, ask the dealer for a quote.

Your code reader may be displaying the wrong bank. I see that often with less advanced tools. - Nick at Pelican Parts
 
mark Comments: The most common fault codes are 2A82 and 2A87 not always but these codes come with it 2A98, 2A99, 29CC.
April 29, 2015
  Followup from the Pelican Staff: If the solenoids were cleaned already, the issue is likely with the actuator. You will have to test the function, look at desired verse actual camshaft angle suing a BMW scan tool. This will confirm it is off and unable to be controlled. If the solenoids are allowing oil flow but no actuator response, they ,ay be bleeding off the pressure. - Nick at Pelican Parts  
mark Comments: Hi there I have a problem with BMW 325i 2005 vin WBAVB16060NB24189 the car has a rough idle at times, I have cleaned the vanos solenoids when the car idles rough there is no engine light coming on but while driving it can turn on the engine light while the car runs fine the fault codes are fot the vanos intake or exhaust and sometimes both of them.When the car has the rough idle I shut the engine down and restart the engine and all is good for the day or sometimes only for 10 minutes. Please help
April 29, 2015
  Followup from the Pelican Staff: What are the fault code numbers is stores? You could have a faulty solenoid or worn actuators. - Nick at Pelican Parts  
Scott Comments: Says the tab for this job is $60, but the part is over a $100? Did I miss something?
April 25, 2015
  Followup from the Pelican Staff: Don't think so. The price may have changed or the tab is wrong. I will have it updated. - Nick at Pelican Parts  
VTkicker Comments: 2008 335i - 2A87 - Exhaust Stiff/Jammed Mechanically Fault. In the event the solenoid fails could one expect to physically see the exhaust cam position out of time when removing the valvecover with the engine off? Or would a solenoid failure prevent the exhaust cam from retarding so it would be stuck in the normal position? My cam is stuck in the retarded position and I am trying to determine if the Solenoid is bad or if the VANOS gear unit is bad. Thank you!
April 24, 2015
  Followup from the Pelican Staff: You can test the solenoid electrically to confirm it is OK. Comm,and it on while monitoring current. If it functions normally, you can assume it is the actuator.- Nick at Pelican Parts  
Ed Comments: Thanks for the direction- reading through the website and threads you guys are brilliant. Thanks again.
April 23, 2015
  Followup from the Pelican Staff: Thanks for the feedback. Glad we could help.
- Nick at Pelican Parts
 
Ed Comments: Thanks for getting back to me - much appreciated.

The codes appear on the "Creator C110 BMW Code reader" as follows:

2716 nockenwellengeber einlass bank 1
275F vanos maximal-anschlag einlass bank 1

Kind regards
Ed
April 23, 2015
  Followup from the Pelican Staff: These are timing faults. Check operation of the VANOS system and camshaft timing. - Nick at Pelican Parts  
Ed Comments: Hi Guys,

I have an e92 M3 83k miles and have the yellow engine light come on. I connected a ODB reader and have the following codes which can be cleared but come back on after a few days.

nockenwellengeber einlass bank 1

vanos maximal-anschlag einlass bank 1

The yellow light also goes away itself sometimes then comes back a few days later.

Seems to drive fine though once warmed up.

Any ideas?

Thanks
Ed
April 21, 2015
  Followup from the Pelican Staff: I would need the p-codes to help. They look like timing faults and engine knock issue. - Nick at Pelican Parts  
sam Comments: I have tested the sensor and it worked fine,and i even swapped it with intake one and the problem still persist. Cleaned the vanos solenoids and tested their coils and they were fine their coils both read 10.5 ohms on the digital multimeter.
April 12, 2015
  Followup from the Pelican Staff: Resistance is not a good test for solenoids. They need to be tested using an amp meter.

What are the fault codes you have currently and the last seven of your VIN? - Nick at Pelican Parts
 
sam Comments: am driving 2004 bmw 120i e87 with n46 engine, i had valtronic error codes, valvetronic servomotor, valvetronic power limitaion, accentric shaft sensor,onxygen sensor heating before catalytic convertor and have replaced the motor and accentric shaft sensor now valvetronic adaptation and cam shaft exhaust sensor cant clear.
April 10, 2015
  Followup from the Pelican Staff: Check the camshaft sensor, it may be faulty. - Nick at Pelican Parts  
ledar Comments: No, there is no "chek engin" light normally or when I unplug them.
After I changed O rings on vanos solenoids, I cleaned connectors and start the car with unpluged exhaust solenoid.
Car run normally and without "check engin" light.
Now I tried with unpluged O2 sensor,car starts normally and RPM was ca.720 constantly.
That was weird.
Reason of this chek is that car is a bit slow. I don´t feel that I have 150 HP.
Thanks for help
March 24, 2015
  Followup from the Pelican Staff: I would check the program on the DME. It may be altered to ignore the MIL light. - Nick at Pelican Parts  
ledar Comments: Hallo!
I have a E90 320i from 2005.I have a problem. If I disconnect vanos solenoid there is no error codes and it is the same situation if I disconnect O2 sensorpre-catalyst.
Running scanmaster show´s nothing.
March 23, 2015
  Followup from the Pelican Staff: Is the check engine light on when you unplug the items? - Nick at Pelican Parts  
Jeff E Comments: I'm having the same problem as you Tim. I have replaced intake vanos solenoid and intake cam sensor. To me it seems kinda random. It may run fine one time, then the next time throw the cam senor code or the vanos code or both and have some weird dip in rpm when the engine is slowin to idle, or maybe when it is just sitting there idling. I'm wondering if faulty wiring could be the cause or some mechanical play in the camshaft itself. Either due to sheared bolt or worn bearings, not sure. Basically if you find the cause please post your resolution. If anyone has thoughts on this please share.
March 19, 2015
  Followup from the Pelican Staff: If you suspect electrical, test the circuit for the sensor and solenoid. This will either confirm or deny your suspicions. As far as mechanical, you can check VANOS operation using a BMW scan tool. If it doesn't reach the desired positions, you could have an oil pressure or actuator issue. - Nick at Pelican Parts  
Tim Comments: Yes,solenoids replaced, CMP replaced, non-return valve replaced. still 2A82, no idea now... Shake like crap when starts, driving is fine; only start shake which gives 2A82.
March 12, 2015
  Followup from the Pelican Staff: You are going to have check mechanical timing, once you confirm it is good, you will have to check the actuators ability to control movement as requested by the DME. This could be an issue with the actuator, camshaft ledges or work timing parts. - Nick at Pelican Parts  
Tim Comments: Hi Nick:
If VANOS adjustment unit or oil duct is dirty, will it affect oil pressure? Causing 2A82?
March 11, 2015
  Followup from the Pelican Staff: It could. Have you tried cleaning the solenoid first? - Nick at Pelican Parts  
Adrian Comments: The car had indicators "Engine malfunction with adverse effect on exhaust emissions" lit up two times in two weeks, and also two times indicator "Full engine power is no longer available" along with bad shaking at idle. Now the car is ok, no warning indicators, no nothing. The BMW dealer said after testing that I need to replace the VANOS exhaust solenoid and the NOX sensor. My question is if the NOX sensor could have been affected by the exhaust solenoid, and maybe I could get away with just replacing the solenoid. Thank you.
March 9, 2015
  Followup from the Pelican Staff: Unlikely. They are probably both just faulty as coincidence. - Nick at Pelican Parts  
Tim Comments: Hi Nick:
I have all those scan tools and how can I actuate it using it?
March 6, 2015
  Followup from the Pelican Staff: Navigate to component activation. Follow the steps for variable camshaft activation. - Nick at Pelican Parts  
Tim Comments: Hi Nick:
I replaced VANOS solenoid, CMP and VANOS filter but still shake and have 2A82, what's the suggestion for the next step. Clean VANOS unit?

Thanks
March 5, 2015
  Followup from the Pelican Staff: The VANOS unit can't be cleaned. It has to be replaced. You could have a faulty unit. You will need a scan tool to actuate it and see how it responds. - Nick at Pelican Parts  
Adrian Comments: Hello. Could a bad VANOS exhaust solenoid trigger an error code for the rear oxygen sensor NOX sensor? Thanks.
March 5, 2015
  Followup from the Pelican Staff: Solenoid, unlikely. You would have a VANOS position code if it were faulty. - Nick at Pelican Parts  
Deano Comments: Hi, I have a 2007 3series coupe e92, my brake pedal has gone hard and I have hardly any brakes with the car running and stopped. Ive taken the vacuum pump pipe off and there isn't any vacuum. The pump itself doesn't seem to have any obvious leak or oil around it. Just checking before tryingto remove it that there isn't any other obvious reasons for no vacuum other than the pump. Thanks
February 23, 2015
  Followup from the Pelican Staff: Vacuum for the brake booster comes from the vacuum pump. If the booster is OK, the pump is likely the problem.- Nick at Pelican Parts  
mike Comments: what does and oil condition sensor do, 2007 bmw 335I. can it cause oil gauge to show no oil and make the engine make noise?
this is in response to my question of 2/15 and your answer
thx, mike
February 17, 2015
  Followup from the Pelican Staff: The sensor monitors the level and condition of the engine oil. If you have noise, check oil pressure. - Nick at Pelican Parts  
mike Comments: I have a 2007, 335i. Dash oil gauge shows no oil even though oil level is good. After doing it intermittently, the engine is making a racket. Is it oil pump or some other problem? Thx, mike
February 15, 2015
  Followup from the Pelican Staff: I would check engine oil pressure. if oil pressure is OK, the oil condition sensor may be faulty. - Nick at Pelican Parts  
Andris Comments: Dear Sir

I am writing to ask for yor advice.
I have got a BMW E90 325i 2006 with 238,000 km.
The "service engine soon" light has been on and off recently.
It has been investigated by a BMW qualified service and the computer showed that the 2nd catalizator is not working properly.
However, there is no limit excess for the CO emmission.
I am just wondering, if the 2nd catalizator were replaced, would that also fix the "service engine soon" light or
could there be other issues behind.

Best Regards,
S A
February 8, 2015
  Followup from the Pelican Staff: If you have a fault code for the cat and you replace it, it should remedy the light. That is as long as there is no item affecting the cat. For example a misfire or improper mixture. - Nick at Pelican Parts  
dre Comments: No , no lights , just the code stored i erase it and came again , may i buy new vanos sensors?
January 27, 2015
  Followup from the Pelican Staff: Sure, if you want. However, I would suggest getting to the problem of the issue. Then you will be sure you are replacing the right part. - Nick at Pelican Parts  
dre Comments: Hello , i have 07 e90 with 44k miles and 2a98 code,i allready clean vanos senors,and change intake camshaft sensor with no luck,the car run just fine at the highway , but if i go pretty slow traffic the car fails like if had bad coil when i accelerate, when i stop the car shakes , then when i accelerate again after 2000-2500 rpm´s it run normaly.
¿If it was a worn mechanic componet can its been posible to run just fine at a 10 mile and up speed?
pd when i start the car its start just fine after 6-10 seconds of normal idle the shaking problem come on , please note all the car services were on date and on the bmw dealer
January 22, 2015
  Followup from the Pelican Staff: Is the check engine light on? Sounds like an engine misfire. I would check spark, fuel and compression on all cylinders. - Nick at Pelican Parts  
Captainchef Comments: My 2006 325i fob remote quit working, I took it to an auto supply store and the device there to test sealed remote showing low batt. My car does not indicate a fault error of batt being low and suppose to recharge when inserted. The drivers door cannot be locked manually using the key outside but presiding the lock key control on the center of the dash locks all doors. Yesterday the secondary fob worked then stopped working again. What do I do with this issue, dealer wants 260 to replace fob.
January 20, 2015
  Followup from the Pelican Staff: I would have the keys tested using a BMW scan tool. If the remote key is faulty, you will have to replace it. - Nick at Pelican Parts  
vantun08 Comments: I have a 2007 BMW 328xi that have the code p0012 it will start than stall with the valvetronic motor connect it, But when I start the car without the valvetronic motor connected, but no power when gas it up. Any idea?
January 7, 2015
  Followup from the Pelican Staff: I would guess mechanical timing is off. Check camshaft actual verse desired using a BMW scan tool. - Nick at Pelican Parts  
dan Comments: Hi Nick, thanks for the fast response.

yes, how i understand it is that BMW only cursed Europe with these ones.. lol

I just thought as the double vanos systems are in some of the 6 cylinders too you may have come across these faults.

here is what I have done so far: changed the VVT ECU and Relay as I found that with it connected its feed would lose voltage ? but the problem is the same.
I have confirmed continuity of the servomotor wiring, but wasn't getting a voltage reading above a 1v at its plug even while engine running. ????

I resistance checked the servo motor too, which checked out - low ohms pin to pin and infinitely high pin to case. - also I have checked the charging voltage at battery 14.2v which is ok and have disconnected each sensor relating to engine control to eliminate those too. caused new codes

any help, however specific or not would be great and much appreciated.

btw i'm the guy with the 316
January 7, 2015
  Followup from the Pelican Staff: If you're mot getting voltage at the motor, the issue may be with the fuse that feeds it, or the DME. See if you can get wiring for the engine to trace the circuit. - Nick at Pelican Parts  
dan Comments: Hi I have a n42 316i UK which has been driving me crazy. 2682 Vanos power supply output stage and 2865 codes which is the limp mode fault. I've swapped the vvt ecu, vvt relay, resistance tested the servo motor but when checking voltage at harness plug for servo motor I'm not getting more then a volt.. Is there any chance you could help?
January 4, 2015
  Followup from the Pelican Staff: Don't have your vehicle here in the US, so I can't be too specific. But I would locate the wiring diagram and check if the Valvetronic motor fuse is blown. I have seen this on 6-cylinder models. - Nick at Pelican Parts  
Beolab Comments: Hi thanks for the fast answear!

sorry i forgot to mention what model:

It is an Bmw E91 318i with the N43 engine.

Do you know the normal values on the fulepumps?

Then i have another question. I can read out that the throttle just opens 85% is that normal or is something wrong here?

Best regards

Fredrik
January 2, 2015
  Followup from the Pelican Staff: What and when are you using for the throttle data? It could be displaying it wrong.

I don't have the fuel pressure values for that engine, we dont have that engine here.

- Nick at Pelican Parts
 
Beolab Comments: Hi! Have the same issue, that the revs jump up and down when you are doing a cold start.

You say it can be a vaccum leak or the fule pump.

With my obd scanner i can see that the highpressure fule pump have a pressure of 150 bar at the fulerail and the lowpressure 7,5 bar.
Is that the normal value?

And if it is a vaccum leak, where do i need to look?

Do you have a tip for me?

Best regards!

Fredrik
January 2, 2015
  Followup from the Pelican Staff: I don't know what vehicle you are working on, so I can not sire about the fuel pressure specs.

Check the intake ducts, manifold and lines for leaks. - Nick at Pelican Parts
 
Sean Comments: hi again - vin a101812. Sorry but that was my interpretation of error code. The actual light that came on was a yellow icon of an engine with half of the egine diagonally split and colour. On this page it's number 41: https://wiki.bentleypublishers.com/plugins/servlet/mobile#content/view/9633840.

Thanks for responding so far :-

Cheers
Sean
December 31, 2014
  Followup from the Pelican Staff: That light indicates reduced power. Could be due to a component failure causing low power, or the DME reducing power due to a misfire. If there is no actual loss of power as you stated, it could be a drop in intake pressure or fuel pressure causing the fault.- Nick at Pelican Parts  
Sean Comments: Hi - I have an e91 320i 170ps 63000k's. I've had this error twice now dme1_ 29 dde1 - engine loss of power but there is no loss of power at at all. The first time the error arose it was around 10 degrees and the second time it was 0 degrees. My odb reader says no error are stored, and both times after restarting the engine the errors were gone. Any idea what the issue could be?

Shaner Comments: Hi Nick, I'm after a little advise on my 325i e90, its feeling underpowered and economy, eml comes and goes, also flat spots at low revs and low gear, I've been aimed toward vanos solenoid by others, what's your thoughts please
December 27, 2014
  Followup from the Pelican Staff: 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. Could be low fuel pressure or a VANOS issue. You don't want to shoot in the dark on this, get those codes and let's go from there.

Sipho Comments: Dear All

My car would not start but cranked fine. After reading this article , I removed the VANOS Solenoids and cleaned them.

The components were indeed dirty and needed cleaning as advised.

I've put 1 liter paraffin into a small container and dipped the VANOS Solenoids for 5min. I them used a clean cloth with an old tooth brush to clean them.

I put them back and the car started like a dream. The car drives even better than before.

Bryan Comments: Hey there, I have a problem with my 2007 BMW 335i as is looking for help!
After warming up the engine, when I do a hard acceleration in any gear, the yellow half engine light would appear. But when I restart the car, the engine light is gone and then the engine light would appear again when I repeat the hard acceleration. When I checked, it gave the code P0012. I've changed both Vanos solenoid with new ones, changed the oil and filter, however it still appears when I hard accelerate. Help is greaty appreciated! Thanks!

Will the sound go away after I change them? Or is there more damage to the engine and have to start looking more into it
First time I own a BMW don't know much about German cars, help please

Adam Comments: Addendum to previous comment: I also pulled the VANOS solenoids, cleaned, put back in swapped. They were not particularly sludged or anything. Also I had it at a shop and before towing it home they guessed there was an issue w/ computer citing injectors dumping too much fuel. I actually removed and opened the DME, saw no physical evidence of problem.
November 22, 2014
  Followup from the Pelican Staff: If the DME is faulty, it is unlikely you will see physical damage. - Nick at Pelican Parts  
Adam Comments: I have a 2007 328i that stalled after CEL then low oil pressure light. Will not restart cranks, stumbles, won't start. I have codes 2A82,2A87. Can faulty VANOS solenoids cause a no start? Could the codes just be a symptom of oil starvation? I have replaced crank position sensor and intake cam position sensor already, with no change in behavior. Compression, spark and fuel pressure are all fine. I've even scoped injector pulse after shop told me the engine was flooding, which looks fine.
November 22, 2014
  Followup from the Pelican Staff: I would think no.

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 fuel pressure, volume and quality. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.

Harry Comments: Hi, I've got a 2008 E92 325i N53 engine. About a month ago I had a misfire, loss of power and eventually went into limp mode, a fault code has come up saying misfire on cylinder 1. Because I owned the car for only 2 months I wanted to make sure that everything is changed and it will run smooth so I changed all 6 injectors, 6 coils, the plugs were 4k miles old, NOx sensor. This cured the misfire and the judder that came along with the misfire, however, since this problem occurred, the car isn't the same anymore as in when I drive at constant speed, and I try to accelerate in a normal fashion, the rev counter goes up about 200 rpms, and instead of continuing to go up, it goes down another 200 rpms, and then back up again like it should normally rev. When I had the car before the problem, it would rev up smoothly with no hesitation, throttle response was very good. To be honest I've spent a lot of money so far trying to guess what it is. There are no codes coming on now. I would really appreciate your advice.
November 13, 2014
  Followup from the Pelican Staff:

Still sounds like an engine misfire. Check fuel pressure, volume and quality.

I would check spark, fuel and compression on all cylinders.

Heinen81 Comments: Hello,

My 2006 e90 325i with 109,000 miles has an inconsistent idle in the mornings, after sitting overnight. It will surge and drop between 100-500 RPM's until I give it rev the engine to 3k, and then it evens out. It also has a 300 rpm drop in RPM's at idle, under load at stop lights, ectwhich causes a slight shudder, and "surge" while on the brakes. No check engine light, and I just changed all coils and plugs... didnt help. much better pickup now, though any ideas?
November 11, 2014
  Followup from the Pelican Staff: Could be a faulty fuel pump or a vacuum leak. I would perform a fuel delivery system test. Check fuel pressure, volume and quality.

edwardd Comments: please help both solenoids are stucked I can't take them out
November 9, 2014
  Followup from the Pelican Staff: If you have all the fasteners removed and the cover is free, the O-rings are stuck. You will have to rotate the solenoid to free it. - Nick at Pelican Parts

gaz330i Comments: Hi. I have an auto e90 330i. Without warning the car cut out whilst driving. The first time it did this today it showed dsc failure on the idrive, then second time showed tyre pressure sensor failure. I have a small code reader which showed codes 2A99, 2D5F, 29D0. I cleared these and took the car back out. This time it didnt cut out but the amber engine light came on and it ran lumpy. Codes showing this time 29d1 combustion misfire cylinder 5, 29d2 combustion misfire cylinder 6, 29d0 combustion misfire cylinder 4. Any ideas?? Would the code 2a99 crankshaft- exhaust camshaft correlation cause the misfire on cylinders 4,5 and 6?
Thanks for any advice.

Lenny K Comments: 06 325i with N52 engine

Car stalls when coming to an idle at times

Code 2A99

Swapped Solenoids, checked exhaust cam ledge,checked cam timing, no oil passage restrictions

Vanos Position Exh -115 Vanos Adaption exh -13.13

Is this a bad Vanos unit?


November 3, 2014
  Followup from the Pelican Staff: Is the VANOS active or stuck in that position? How did you check timing and the camshaft ledge? If they are all good, as you mentioned, only thing left is the actuators. - Nick at Pelican Parts  
Gaz Comments: Hi, Just a quick question - do the Vanos O-rings have any effect on idle speed if they are faulty or are the solenoids more likely in need of cleaning. I have a rough idle when warm which goes away if A/C is switched on higher rpm. Checked vacuum side of things with Carb cleaner - seems to be OK. No fault codes, Plugs/Coils check OK ? Any info appreciated.
November 1, 2014
  Followup from the Pelican Staff: You didn't mention what vehicle you arr working on. Carb cleaner is unsafe to spray on an engine due to fire hazard. Plus the days of finding a vacuum leak by just spraying something are over. Modern DMEs controls rpm too well. You need to use a scan tool and fuel trim to test for a vacuum leak. - Nick at Pelican Parts  
Sunny Comments: I recently got an engine top overhaul for my 320i E90. It gives a slight misfire / vibration when I start the car after 7-8 hours. Can you suggest whether this is linked to spark plug or coil or vanos solenoid. Once the car warms up this problem goes away. Also I would like to share that I was not having any issue before the engine top overhaul. Also there are no error codes so far

nirvanabob Comments: Hi I drive bmw 335i 2007 and I gotta the code 2a82 from a couple of months! I already change a lot of staff like vanos solenoid, camshaft position sensor valve cover, etch and still have the problem. When I start the car in the morning shake, hesitate, and the shift is like crap! When it is warm is little bit better! So, the last thing I can do is to check the camshaft bearing ledge? Or check for vacuum leak or something else? Please let me know sometimes!
September 12, 2014
  Followup from the Pelican Staff: This could be an oil pressure issue or flow to VANOS units. The bearing ledge is common, that diagnosis is tough without factory tools. You can start by monitoring camshaft actual and desired position. If the angles are off and you will need to dig deeper.- Nick at Pelican Parts

Phil Comments: I just bought a used 2008 328i sedan. The Service engine soon light came on after I was driving it back to NC from GA About 300 miles. I took it to a shop and getting the fault code p0012 referencing the "camshaft timing over-retarded bank 1". The car runs completely fine except it has stalled randomly at two stop lights but immediately starts back up and works well. The two stalling episodes happened far apart. What exactly will have to be replaced? and whats an estimate on how much will it cost to get it fixed at independent shop?
August 31, 2014
  Followup from the Pelican Staff: I can't help with an estimate, you'll have to call around to shops to get that.

This could be a sensor issue or mechanical timing. You will have to check engine timing via a scan tool, then if needed confirm mechanical timing is OK. - Nick at Pelican Parts
 
normelton Comments: My OBD-II scanner is reading P1554, I'm planning on replacing the solenoids. My question is ... how are folks reading BMW-specific error codes? Like 2A98, 2A82, etc.

  Followup from the Pelican Staff: Those codes are likely read using an advanced BMW scan tool. - Nick at Pelican Parts  
Darrin Comments: Thanks for your great howtos and help! I did plugs and coils a few weeks ago on my '06 325xi to troubleshoot a seeking cold idle issue and now I discovered this writeup for VANOS solenoids which was probably my issue to begin with!

So I'll clean these solenoids this weekend but wanted to ask, is it OK to use throttle body cleaner or some other product to clean the solenoids more completely, or is compressed air the only thing I should use on these things?

Thanks!

Haas Comments: 2006 530i N52 made in 04/2005 with 161xxx miles

I keep getting a 2a87 fault showing up through DIS only, telling me there is a Exhaust Solenoid issue. Other symptoms include:
-adding a quart of oil every 450 miles but no smoke produced and no leaks
-RPM surges
-very rarely a misfire-like symptom new coils/plugs are in

No other codes. I cleared the code and then swapped the VANOS solenoids, but the fault still comes up in the 2a87 Exhaust not the intake, so I am now leaning to the bearing ledge...? Before I dive into taking this bad boy apart, am I missing anything else? Would this issue take care of the oil consumption too? Can it still be the VANOS solenoid?
July 29, 2014
  Followup from the Pelican Staff: I haven't seen the bearing journals cause oil consumption, when bleeding off VANOS pressure. Likely two issues. I would check the timing of the engine before jumping in too deep. The chain guides may be worn from the oil consumption issue. - Nick at Pelican Parts

Curtis Comments: I have a 2009 e93 with a p0015 fault code. Everything I find points toward the vanos, but it sounds like a vacuum leak. Before the engine is warmed up, it runs smoothly. After it warms up,about 10 minutes of driving, it will not idle correctly and I hear a whining/whistling noise. When I give it throttle, the noise goes away and it runs smoothly. Can a vacuum leak through a p0015 code? Or does this have to be something with the VANOS? Thanks!

rcp71 Comments: Hi, I purchased new BMW 750 LI X Drive, after only 450 miles on it, it flashed drive train malfunction. Technician at the dealership ran some tests and said VANOS Solenoid needs to be replaced, and he replaced that yesterday. I am very disappointed, as such an expensive car with only 450 miles on it it should not happen. From your blog I thought VANOS Solenoid problem happens only after long mileage. Can it happen only after 450 miles on it? How big is the problem? Will it reoccur in the future? I was wondering do I need to hire a lawyer or something to replace this car with a new car.

So i notice that the car has rough start, vibration, and hesitate when accelerate.
This is the fault report:
Engine / Motor:
- Fault: Activate secondary air valve / Ubat outside ULF / Fuel trim bank 1 limit values / engine failure
- Code: BMW 2A82

Code: bmw 2a82
Fault: supply voltage
Code: bmw 3100
So, I do some research on website and I found that the problem is the tmap air sensor, can be that?
I already change everything spark, vanos solenoid, camshaft sensor etc!
Let me know bye

  Followup from the Pelican Staff: The fault codes are not complete. I would need the last seven of your vehicle;s VIN and the BMW ot P-codes for your vehicle. - Nick at Pelican Parts  
kofi Comments: Just changed the vanos solenoids on an 05 e90. I still have the check engine light on. How long until it goes away. I changed both as the car was going into limp mode after driving and parking for a while wouldn't happen after engine had totally cooled down. Any ideas on how long until the check engine light goes away
July 8, 2014
  Followup from the Pelican Staff: The fault will have to be gone for two consecutive trips, then it will go away on the next drive cycle. A total of three. - Nick at Pelican Parts  
Rain Comments: Does anyone know if it's resonable for the camshaft bearning ledges & vanos solenoid valves to fail on a 2008 335xi that has 86k miles?
July 3, 2014
  Followup from the Pelican Staff: I would say so. Especially if the engine wasn't maintained well. - Nick at Pelican Parts  
Aminu Comments: Hi. I have an e87 with VIN PS32733. I have a P0012 code. I just changed the VANOS solenoid for the intake. The code is stil there. My questions are: 1. what is the difference between solenoid and actuator, 2. Is it possible that a leak in the oil filter housing is the cause, 3. If it is a mechanical timing issue, how do I go about fixing it?
June 24, 2014
  Followup from the Pelican Staff: Solenoid is the electrical component. The actuator is the mechanical component.

Unlikely the leaky oil filter housing is to blame

By checking if the problem with the timing is due to a faulty actuator or to timing being incorrect. You will need to monitor desired and actual VANOS actuation. You will need to install timing jigs o confirm timing is set correctly. - Nick at Pelican Parts
 
Hummer Comments: Hi, I have an 06 325i that has an intermittent no start condition but only when the car is at operating temp.Could this be due to a bad Vanos solenoid? The lower solenoid is oily like its been leaking for a while & when looking in the oil fill hole you can see caked up engine oil like the prior owner seriously neglected changing the oil. Anyway just wondering If a Vanos solenoid may be what I need. Thanks
June 22, 2014
  Followup from the Pelican Staff: I don't think so. Sounds more like a sensor failing once it gets hot. 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.

i will appreciate for your assistance.
June 1, 2014
  Followup from the Pelican Staff: Sounds like a fault for a circuit or wiring to the VANOS actuator solenoid. I would check that the wiring isn't broken or shorted. - Nick at Pelican Parts

bpatmurray Comments: Hello there, great article. Just yesterday by 07 328i started to have trouble starting and is idling rough. Power curve seems ok and the care is driving well. No stalling... yet. My OBD read 2A9A. I am trying to figure if I should start with replacing solenoids or cam sensor. I did have the sensor replaced due to a broken gasket just under 1 yr ago by BMW dealer. Any suggestions?
May 15, 2014
  Followup from the Pelican Staff: I would start by removing and cleaning the solenoids. That may remedy the fault, if not, you may need to replace them. - Nick at Pelican Parts  
nirvanabob Comments: I checkd DME fault code and comes the code 2a82 Inlet-Vanos variable cam control test! Now what can I do?
May 7, 2014
  Followup from the Pelican Staff: Sounds like the intake VANOS is failing a test. Using your scan tool. check actual verse desired VANOS angles. If off, the actuator may be faulty. - Nick at Pelican Parts  
nirvanabob Comments: Thanks for the answer! So, now after change the booth vanos solenoid and booth camshaft position sensor the engine light it just come 2 times and then it disappear again, what about the rpm? It's normal that when the car is already warm and I turn it on the rpm go up to 900/1000 and after 20 second they go down normaly around 650/670, and it's normal that the engine oil comes black? Let me know I really appreciated!
May 6, 2014
  Followup from the Pelican Staff: The fault code being set will help direct you to the problem. The idle issue can be cause by many things. You can have worn or faulty VANOS parts. 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.
- Nick at Pelican Parts
 
nirvanabob Comments: Hi, may I ask you a question?
I just replaced on my BMW 335i 2007 both vanos solenoids and camshaft sensors, because the engine light went on with the only code P0012 "A" camshaft position timing over retarded bank 1. I also changed the oil and the filter many times in a row and it was always really black and dirty.
Even if I did all these adjustments I still notice that the RPM go down slowly when I start the car that is already warm and the engine light has gone on again once. So my question is: is it possible that i need to replace also the sparks plug? I don't know the last time they were changed because i bought the car last september!
Thank you
April 28, 2014
  Followup from the Pelican Staff: Spark plugs usually won't cause an idle dip. Is the check engine light ON? Have you check for vacuum leaks? 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.

Mike Comments: What is coming out of the solenoids when you clean them? How is the engine oil? - Nick at Pelican Parts
****************
The oil is good, using, mobilone changed every 4 months, much more frequently than the BMW requirements specify. There does not seem to be much coming from the solenoids when I clean them. The gasoline I use as a solvent turns dark and very little if anything comes out when I use compressed air to clean and dry them.
April 23, 2014
  Followup from the Pelican Staff: If there is no debris, I wouldn't think it's cleaning that is helping. You may have a faulty solenoid. - Nick at Pelican Parts  
Mike Comments: I'm not getting any check engine light or other dash lights, but there seems to be a kind of flat spot in acceleration around 3k-4k rpm with mildly degraded gas mileage. If I take the solenoids out and soak them in gasoline overnight, blow them out the next morning and re-install, performance improves for a few days. Sound like they're shot to you guys?
April 22, 2014
  Followup from the Pelican Staff: Could also be debris in the VANOS system. What is coming out of the solenoids when you clean them? How is the engine oil? - Nick at Pelican Parts  
Bill Comments: Im having issues with my 335I im getting the 2A82 & 3100 code i have replaced both solenoids with brand new ones and i still recieved the check engine light, next i recplaced the sprocket and the sensor and still the recieved the same codes i dont know what to do any help weill be appreciated. thank you
April 22, 2014
  Followup from the Pelican Staff: You could have a mechanical engine timing issue. I would check desired and actual camshaft position using a BMW scan tool. - Nick at Pelican Parts  
BMWCAT Comments: Hi,I got in the car this morning and as I drove off the engine sounded a little different, I turned off radio and the big engine light came on and car lost power. Kept foot on clutch and it kept trying to auto restart. Plugged in OBD and got P1553. Managed to get it to run and get to work, but thinking it sounds like these solenoids? BMW 320 cabriolet 07. Is changing the best course of action?
April 4, 2014
  Followup from the Pelican Staff: If the solenoids did cause the fault, I prefer to replace them... over cleaning them. - Nick at Pelican Parts  
carlos Comments: could a sticky solenoid be the cause of a P0012 intake camshaft position timing order retarded?
April 2, 2014
  Followup from the Pelican Staff: It could be. So could a faulty VANOS actuator. - Nick at Pelican Parts  
carlos Comments: why can't we reuse the fastener?

JR Comments: HI I have a 2008 BMW 328i.I have a check engine light on the code is P1777 can u please help me.....
March 29, 2014
  Followup from the Pelican Staff: The code description is P1777 Ignition Retard Request Circuit Fault

I would run a full scan using a BMW scan tool, to be sure it has been displayed correctly. - Nick at Pelican Parts
 
mohanad Comments: i have bmw e90 328i i did not drive it for 10 days and after that whn i try to drive it bad sound come from the engine after 20 seconds of the starting and when i turn it of and start it again the sound come again from the valves after 20 seconds i change the oil and it was bad and the sound still come after 20 seconds , is the problem from the vanos solenoids
March 4, 2014
  Followup from the Pelican Staff: Not sure, I would have to hear the noise. You may have a mechanical engine failure. Start by checking the oil level, then oil pressure. - Nick at Pelican Parts  
Dave2512 Comments: Hi my 2007 335i keeps throwing engine fault reduced power after starting and moving off. It started doing it every couple of days now it does it every time the car is started. When it first starts it searches for the idle point then throws the code and sits at the correct idle. I've also noticed when it does this the fan comes on and stays on all the time whilst driving. Any advice would be appreciated!
February 20, 2014
  Followup from the Pelican Staff: 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. Could be an air or fuel issue. - Nick at Pelican Parts  
Fdc Comments: Sorry i thought I was ina bmw specific forum. I have a 2006 BMW 325 xi
February 19, 2014
  Followup from the Pelican Staff: It is, however without knowing what vehicle you have it is difficult to offer advice.

The C prefixed fault code designates a chassis fault. I would have the vehicle scanned using a BMW scan tool, as this will give the BMW specific fault code. The code appears to describe a describe a short or open in a solenoid for the front axle or all wheel drive system. - Nick at Pelican Parts
 
fdc Comments: I am getting error code C1303 on car-ii-codes.com says "Right Front Axle Solenoid Valve Hold Open/Shortened?
Is this the VANOS solenoid ? Can you tell from the error code if is the exhaust or the intake I should try to clean?
February 16, 2014
  Followup from the Pelican Staff: Not sure what vehicle you have. but a code referring an axle, sounds like a drivetrain code. - Nick at Pelican Parts  
john b Comments: Why do you need to discard the 10mm bolt and use a new one?

Thanks,
February 13, 2014
  Followup from the Pelican Staff: See this tech article about nonpreusable fasteners: http://www.pelicanparts.com/BMW/techarticles/BMW-3-Series-E90/ENGINE-Nonresusable_Fasteners/ENGINE-Nonresusable_Fasteners.htm - Nick at Pelican Parts  
Andy Comments: Thank you Pelican Staff for writing such a good article! I did the repair successfully. Engine light no longer comes on and the car accelerates VERY smoothly. The only issue is now the MPG has dropped about 20% from pre-fixing. Any thoughts why?
January 30, 2014
  Followup from the Pelican Staff: Not sure. Has the weather changed? Are you idling the vehicle longer? - Nick at Pelican Parts  
RAFAEL MARTINEZ Comments: Hi, guys excellent work with all this tech articles.
In regard to this one, I just did the job today 2006 325i and found particles of oil solidified inside the tube, impeding the spring to open properly, with some carb cleaner it got clean and you know it is free, hitting it against your hand palm and listening the valve open free.
You can also with a pair of alligator ended jump cables test with 12 VDC no polarity neededthe solenoid open and close of the valve. Besides testing the sensor is so easy following your instructions and you troubleshoot it in a breeze.
THANKS AGAIN GREAT JOB

mark Comments: I have a 07 328i, previous owner let it sit for a while, drove it for 5k. Car was due for oil change. service light came on and off a couple times. Got oil change and received codes 2a99, 2a98, 2a87, 2aa5. planning to replace both solenoids. can the cam lifters and rollers also be affected? it has only 45k miles. slight ticking noise coming from engine when idle...what can it be?
December 30, 2013
  Followup from the Pelican Staff: Noises are hard to give advice on, but first be sure your oil level is correct.

I would start by replacing the solenoids and seeing where that gets you. if the faults return you will have to dig deeper. IE: VANOS actuators, lifter parts, etc. - Nick at Pelican Parts
 
Wissam Comments: E90 325 2006 service engine soon
The fault code: 2A2E mixture control
I replace: air mass, Intake manifold, Oil separator.
I also cheque the oil cap, fuel cap.
Again the light will come again after 10 mile of driving
Pls if you have any idea about thi issue
Thanks

December 29, 2013
  Followup from the Pelican Staff: I would smoke the engine for vacuum leaks. Once you are sure there are none, check operation of the air/fuel ratio sensors. If one is faulty it could cause an erroneous code. - Nick at Pelican Parts  
Bish Comments: My Scanner says its the same two codes, P1553 and P1554. Although it really shows that I have four codes P1553, P1554, P1553 PD and P1554 PD. These PD codes according to my scanner means that they have been stored in the system. So far, I have not seen any other codes than these two types.
December 17, 2013
  Followup from the Pelican Staff: Try swapping the VANOS solenoids bank to bank. If the fault codes change with the solenoids, replace them. If that doesn't do it, the VANOS actuator may be dirty. - Nick at Pelican Parts  
Bish Comments: I got Service engine soon light in my 330 xi 2006. The OBD II scanner I have read as P1554. I took it to my mechanic and he cleaned the vanos solenoids for me. He did not have the right tool to delete the codes. Then his scanner detected P1553 and P1554 after the cleaning. I drove it home since he said it might go away. The light comes on and goes off by itself. It stays on and after a few times of starting the car and turning it off it goes away. Can you please help? The oil level on the dashboard computer says its perfect. I don't know what else to check.
December 13, 2013
  Followup from the Pelican Staff: if the MIL is coming on and off, the fault code is likely returning, or a new one. Have you checked to see what code is stored? - Nick at Pelican Parts  
sean Comments: I just changed the oil.. no check engine lught anymore.. maybe the dirty oil made it tough for the solenoid to get a reading
November 13, 2013
  Followup from the Pelican Staff: Dirty oil is bad for VANOS components. Thanks for the update. - Nick at Pelican Parts  
sean Comments: I have a 2008 bmw 328i coupe with p0015 thrown. was thinking of doing this myself first before spending 400+ bux at the dealer. im guessing its just one of the two solenoids maybe that should be cleaned/replaced.
November 11, 2013
  Followup from the Pelican Staff: I would go for it. Try swapping the solenoids first and seeing if the fault follows the solenoid. if it does, replace it. - Nick at Pelican Parts  
tony Comments: I have the same problem as e92pprwght and my 08 bmw328 xi is doing the sae thing replace vanos seloineds ,camshaft position sensor ad the carr cranks but no start,any advice

e92pprwght Comments: I need some help. I had the No. 2 Cylinder fault at 100k all mineI did a complete tune up, Coils, Plugs, Cam position sensors, the Vanos solenoids, and air filters. My 2008 e92 now wont start, it cranks and it sounds like it wants to but wont. I have a fully charged battery, my fuel pump is working, I am not getting any codes, no burnt fuses and was running fine before hand.... other than the no.2 cylinder. Please Help.
September 29, 2013
  Followup from the Pelican Staff: I would check all of the connections for the coils and sensors that you replaced. Make sure everything is plugged in tight and the ground cables are connected.

September 17, 2013
  Followup from the Pelican Staff: If the VANOS unit is jamming it can cause an engine stall. Especially with a drop in engine vacuum. 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.- Nick at Pelican Parts

Joe Comments: theres 2 solenoids valves,are iqual or diferent from each other?
August 10, 2013
  Followup from the Pelican Staff: On E90 models, the solenoids are the same. I would double check the part numbers of your vehicle. But when I suspect one is faulty, I swap sides, if the fault follows the solenoids, I know the solenoid is faulty. - Nick at Pelican Parts
