     The later-model E36 six-cylinder engines have a mechanism that allows for variable advancing of the camshaft timing. The VANOS unit (Variable Onckenwellen Steuerung) is an electromechanical unit that uses a hydraulic piston to accelerate the camshaft timing at higher rpm. This unit is controlled electronically by a solenoid connected to the engine management system (DME).

    
The VANOS unit is hydraulically operated using pressurized oil from the engine. As such, the oil line that feeds the VANOS unit often begins to leak from age. It’s very common for this line to weep oil and leak it on top of the engine. To replace it, you will need to remove the intake manifold first in order to gain access (see our intake manifold removal article). Once the manifold is off, removal of the line is as easy as disconnecting the two banjo bolts on each end, and removing and replacing the line. Use new aluminum sealing rings when you install the new line.

    
Also accessible is the VANOS unit solenoid. This unit is responsible for actuating a valve that opens and allows pressurized oil to flow into the VANOS unit. To remove and replace this solenoid, you will also need to remove the intake manifold, as the electrical connector for the solenoid is hidden under the manifold. Be sure to use a new O-ring on the VANOS solenoid when you install its replacement.

Figure 1
This photo shows the two ends of the VANOS oil supply line. On the left, you see the point where it mounts to the VANOS unit. On the right, the line snakes down under the intake manifold and mounts just behind the oil filter housing (yellow arrow). As you can see, the oil line has been leaking and is wet with oil. When installing the new line, use new sealing rings at both ends (green arrows). If you reuse the old sealing rings, they may end up leaking.

Figure 2
This photo shows the removal of the VANOS unit solenoid. The solenoid opens a valve that allows oil into the VANOS unit, which then advances the camshaft timing.  Use a 32-millimeter wrench to loosen the solenoid from the VANOS unit housing. The inset on the lower left shows the inside of the solenoid. Use a new O-ring when reinstalling the solenoid. The inset on the lower right shows the valve in the VANOS unit that the solenoid opens. The light blue arrow at the top shows the camshaft position sensor (Project 14). The VANOS solenoid must be removed in order to install the camshaft position sensor into the cylinder head.

Comments and Suggestions:
Somebodeee Comments: Hello I have a 2003 325xi and I just replace all the O rings of the dual vanos the oil line its new there is no oil leak in the car and the solenoids are working both intake and exhaust I even switched them but I still having my SES light on and the code that Im getting says its the exhaust camshaft position solenoid, ah I forgot the camshaft position sensor its new as well....I could use some help please....
August 23, 2014
  Followup from the Pelican Staff: You could have a mechanical timing issue or a faulty VANOS actuator. - Nick at Pelican Parts  
Bobbob455 Comments: My n42 sounds like a diesel when warm, terrible rattle from the top end. However the noise stops immediately if I unplug any of the sensors on the engine or MAF. I've replaced camchain, guides & tensioner, both vanos units, and valvetronic cam sensor with no change to the noise. If I leave a sensor unplugged the engine sounds quiet & smooth, but has less power. & uses more fuel. Last chance to sort it out before I get rid, it's driving me mad.
PS no fault codes
June 25, 2014
  Followup from the Pelican Staff: What sensor are you unplugging? When you unplug it, what fault code is set? - Nick at Pelican Parts  
Slackman Comments: I have replaced both camshaft sensors and vanoss changed oil and filter. Car still stumbles at start up, then idles fine, but again SES light comes on. Codes are 2aa1 2a98, 2fod. Not sure what else I should do Please help.
June 22, 2014
  Followup from the Pelican Staff: I don't know what vehicle you are working on. But the issue may be with the VANOS actuator or a mechanical timing problem. - Nick at Pelican Parts  
Nazar Comments: How do you replace the valve that the solenoid opens??
May 6, 2014
  Followup from the Pelican Staff: See this tech article:

Steve m Comments: If vanos solenoid was replaced wrong .can it caused a clog in engine .to where there no oil going through and burning engine? 08 335i
April 24, 2014
  Followup from the Pelican Staff: Debris could get in the oil passages. If you are having an oil pressure concern. I would check oil level and pressure. - Nick at Pelican Parts  
K-Smith Comments: Hi Pelican parts, I was wondering when removing the vanos oil line will there be a big amount of oil leaking from the vanos inlet or oil filter housing?
April 12, 2014
  Followup from the Pelican Staff: Not a large amount, but oil will leak out. - Nick at Pelican Parts  
mrtucktuck Comments: Nick: Thanks for the feedback! Ended up being a bad starter, the spur gear was bouncing off the flywheel. I replaced the starter without pulling the intake manifold, or dropping the transmission crossmember..... Never again!
March 28, 2014
  Followup from the Pelican Staff: Thanks for the follow up. We appreciate it.
- Nick at Pelican Parts
 
Jerry Comments: I have 2006 BMW 325xit wagon; the vanos solenoids were replaced about 1 month ago by the dealer. Yesterday my U-joint broke and apparently the drive shaft and joint now has to be replaced. Was the original repair done improperly causing this to happen?
March 26, 2014
  Followup from the Pelican Staff: I would say no, as the driveshaft is no where near the VANOS solenoids. - Nick at Pelican Parts  
MrTuckTuck Comments: I've got a 1998 318ti. Runs smooth, no CEL... However, it sounds like a blender with a bad bearing, and seems to be coming from the lower half of the intake manifold. I started researching VANOS, but that doesn't really seem to fit what I'm hearing. Any ideas?
March 25, 2014
  Followup from the Pelican Staff: Could be a bad bearing in an engine accessory. Try removing the drive belts, does the noise go away? - Nick at Pelican Parts  
Paddy Comments: Hi Nick,
Probably already been answered, but I'm going to be replacing the seals on my vanos unit 2002 330i while performing a valve cover gasket replacement. My question is, if I'm just replacing the seals, will I also need to re-time, or is that only necessary when performing camshaft adjustments?
March 25, 2014
  Followup from the Pelican Staff: If you are remving the VANOS unit to rebuild it, you will have to lock the engine down with tools. You will have to confirm the camshaft timing when reinstalling. - Nick at Pelican Parts  
Dan Comments: Hi, I have a 2003 BMW e46 330i with approx 100,000 miles. This winter on the coldest of mornings 10 degrees Fahrenheit or so my car will start right up but after idleing for several seconds will get very erratic and eventually stall. After a few restarts it is fine but in the meantime all my gauges will go haywire and my CEL will come on although the car will drive fine. After a few drives the CEL light will go away and all will be normal until the next very cold morning - although I do notice it idles ever so slightly rougher regardless of temp.

I have not noticed a decrease in gas mileage or any other symptoms but I can smell what I think is oil burning after the car has been driven but i am ideling at a stop light or whatever. I check the oil level regularly and must be losing a very small amount but I can definitely smell something when ideling after the engine is at temp

After doing some research it has led me to the Vanos but I admittedly have no car knowledge which is why I am reaching out. Am I on the right track?

There is also a rattling sound from the engine when a cold start. Can you tell me everything I will need to get? Vanos hose, solenoids, seals? I will need to find a garage to do this work so can you give me an estimate on time as well? I really appreciate any help with this! I understand you cannot accurately diagnose the issue sight unseen but I am willing to start with Vanos and just want to buy everything I will need to replace.
March 21, 2014
  Followup from the Pelican Staff: This could be a faulty camshaft sensor or a jamming VANOS. 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
 
Tony Comments: Hi I have a 2000 BMW 323i. Code reader was giving me 0340 0004 1100 error codes. For 1100, I have used MAF cleaner on the MAF sensor and the code is still after code reset. For code 0340, will it go away if I replace the intake camshaft position censor. Thanks in advance!
March 21, 2014
  Followup from the Pelican Staff: The 340 may be remedied by a camshaft sensor. SHould be in the intake sensor. Confirm that.

The MAF code may require a new sensor. You cannot clean hot film maf sensors. - Nick at Pelican Parts
 
khaled Comments: Hi Nick
I have e60 m5, I hear rattling sound on driver side cyl bank on a cold start and often hear it during normal driving. I HAD oil pump fault code.. could this be vanos sound?
March 18, 2014
  Followup from the Pelican Staff: It could be. I would check oil level and pressure before digging too deep. You will want to see if the rattle is there at cold, then immediately goes away once the initial idle increase stops. That may indicate VANOS. - Nick at Pelican Parts  
alex5er Comments: I'm trying to check the voltage on the vanos selinoid it read 0 volt with the motor on. Is this correct. My cold reader states that vanos stuck or jamming. 1997 528i single vanos. Other code p1519
February 15, 2014
  Followup from the Pelican Staff: Jamming means it is not moving. The VANOS voltage will vary depending on desired position, via the DME. I would check to see if it is working via a scan tool. Check desired and actual values. - Nick at Pelican Parts  
bj Comments: i have looked all over the car and the internet but cant find the relay or fuses for the vanos solenoid. they are obviously blown or burnt out i have checked all the usual places but cant find it.
February 13, 2014
  Followup from the Pelican Staff: What makes you think they are blown? I don't know what vehicle you have, but go to pelicanparts.com and grab a repair manual. It will list the fuses for your vehicle. - Nick at Pelican Parts  
bj Comments: 2003 BMW e46 M3 -i took the vanos solenoid plug out and put a test light in the end of the plug with ignition on and while turning engine over - test light didnt light up at any stage. does this mean no power is going to vanos solenoid ?will this be why it turns over but no start ?
February 12, 2014
  Followup from the Pelican Staff: It is not a good idea to test DME outputs using a test light. You should be using a high impedance DVOM. I would now think what you found is causing a no start. - Nick at Pelican Parts  
BMW Bummed Comments: I Checked the system after clearing the codes. 3 codes returned 0740 torque converter, 1188 bank 1 snsr 1, 1189 bank 2 snsr 1. Should I replace the Vanos oil hose that leaks. Still runs / idling has pausing. Replaced the boot with branch at throttle body.
February 11, 2014
  Followup from the Pelican Staff: If the oil line is leaking yes, I would replace it. The sensor codes may be remedied by the intake boot replacement. Once cleared, only time will tell if they return. - Nick at Pelican Parts  
BMW Bummed Comments: Man, oh man. I got too many codes. I've got a E39 with almost 160K. Problems with the rough idling. Had the trans mission module cog wheel light come on but it seems it was low on turns fluid. Filled now. Light was intermittent. Not sure why burning through so much, it was filled earlier last year. Lately EML light.
Codes: 1250 gas, 1188 bank1 snsr 1, 1189 bank 2 snsr 1, 1477 leakage pump reed switch didn't open, 0101 air flow snsr crct, 0740 torque converter circuit open trans right, 1510 idle speed cntrl vlv stuck open, 0170 fuel trim bank 1, 0173 fuel trim bank 2.
Cleaned the manifold actuator, throttle body & speed idle cntrl vlv. Cleared codes & engine light back on again.I changed boot for throttle body cause had cracks. Didn't get a chance yet to look at codes yet. The hose for Vanos oil supply line is leaking. Sorry, I got a lot going on & had to put it in here, any thoughts ?
February 8, 2014
  Followup from the Pelican Staff: I would choose one or two fault codes and address them first. Chasing them all at once will be quite difficult. Start with the oxygen sensor codes, check if the sensors are switching, if they are, confirm there are no vacuum leaks of fuel trim issues. If no issues are found the sensor may be faulty. - Nick at Pelican Parts  
bj Comments: can a blocked or dirty vanos solenoid stop the car starting altogether ? my e46 m3 smg started for the first time in two years ran beautiful for 30 seconds i turned engine off and then tried re-start and it ran terribly rough so i turned it off and cleaned the fuel system out totally from tank to injectors including new filter but still just turns over but no start. could this be a dirty or blocked vanos ?
February 8, 2014
  Followup from the Pelican Staff: I have seen a jammed VANOS actuator cause a rough start and rough idle with a stall, but not a no start. - Nick at Pelican Parts  
avp Comments: I have a 2003 530i E39 - M54 Engine with about 105,000 miles. I have a leaking vanos oil hose which I am about to replace. As I read your instructions, I am leary about having to remove the intake manifold in order to replace this hose. It seems the room is tight, but I may not need to remove the intake manifold. Your thoughts? Should I remove the Oil Filter housing instead to get to the bottom of the oil hose? thanks
February 7, 2014
  Followup from the Pelican Staff: You don't have to remove the intake to service the VANOS hose on M54 engines. Just removed the components attached to the front if it. - Nick at Pelican Parts  
timbie Comments: hi i have a 1995 325is and i am having a few issues with it. first when i bought the car it had sluggish acceleration until you got past 3000 rpm and would also idle at 1500 rpm. i dont know what was causing that but now with the negative temperatures it is starting to take me 15 minutes just to get it started in the morning. it will start then stop then you have to give it gas and rev it up until the motor runs smooth and then it will idle exhaust smells like gas during this time what could be wrong with my car? there is no engine codes
January 28, 2014
  Followup from the Pelican Staff: I would perform a fuel delivery system test. Check fuel pressure, volume and quality. If it is good, check spark when the problem is present. Weak spark could cause the engine to flood.
- Nick at Pelican Parts
 
MV Comments: I had the vanos oil hose replaced on 2004 330 xi E46 and now the service engine soon light is on with code for vanos exhaust actuator. The mechanic who performed hose change said it may be due to higher oil pressure after hose change that may have caused the o-ring on vanos exhaust side to leak resulting in loss of pressure and fault code. Claims it is unrelated to hose change and big $$$ to take apart vanos unit to replace o-ring. Does not make sense to me. Can the fault be related to vanos hose change or is it unrelated? Thanks.
January 17, 2014
  Followup from the Pelican Staff: Replacing the hose should not create a pressure change, so I don't see how that would cause the VANOS seal to fail. It could be coincidence or a it failed when the system was disturbed. - Nick at Pelican Parts  
Ed Grubermz Comments: I have recently acquired a BMW 1995 840 CI that has 70,000 miles on it and it was driving fine up until the temperature dropped into the low teens and the brakes started making an odd and loud grinding noise when released. Over the last 2 days the power steering has been making every effort to progressively and completely disappear while inheriting the loud grind sound from the breaks. This is my first BMW and while I'm keenly aware of my prodigious ignorance concerning tugs vehicle the mech's are not which usually Results in me getting the car back worse than when I left it. Any ideas?
January 12, 2014
  Followup from the Pelican Staff: The power steering is likely related to the cold. Try flushing the and replacing fluid first and seeing if that helps. The brake noise could be worn out brakes, I would have them inspected.- Nick at Pelican Parts  
Bill Comments: vanos rebuild video for a car, preferably m54, with a double vanos system available? looked and couldnt find it. just a bunch of random half explained vanos rebuild videos. any help here?
January 7, 2014
  Followup from the Pelican Staff: Thanks for the feedback. If we get the chance to perform the procedure, we will document it. - Nick at Pelican Parts  
sim91 Comments: hi have a bmw e46 320i 2001 been having a few problems lately, the car started misfiring so i changed all 6 coils, camshaft and crankshaft sesnor and all 4 lambda sensor. i work for allparts so i used all orignal bosch and simens parts all oe quality. just now when i start it in the morning first thing when its cold its misfires and as it warms up the misfire dissapers any help also occasionly loss of power as im driving maybe vanos ? thanks simon
December 30, 2013
  Followup from the Pelican Staff: I would start by checking the engine for vacuum leaks. Usually a jamming VANOS will make noise and cause the vehicle to stall. - Nick at Pelican Parts  
merbs Comments: My friend just bought an 07 X3,now oil is puddling on top of the oil filter housing,also sounds like an accessory belt noise coming from the vanos area,could that be the vanos system making the noise?Ive worked on cars for decades but am no BMW tech,how hard is changing the oil filter housing seals? Your site is killer! Info is the key to everything!
December 17, 2013
  Followup from the Pelican Staff: This could be a leaking valve cover gasket or the oil pressure switch in the oil filter housing. Check both for signs of fresh oil, indicated by a clean wet spot.

The noise could be the timing chain or VANOS. You will have to pinpoint, if you cannot. I would suggest taking it to a BMW mechanic before it worsens. - Nick at Pelican Parts
 
Eddie Comments: Hey Nick, thanks for the reply. I forgot to mention an important detail. I also had the battery replaced. Both the old and new battery are both 720. I have not had the battery registered because they are both the same strength and I was told it was not needed. Would the car need to "relearn" with the new battery? Thanks again for the help.
November 29, 2013
  Followup from the Pelican Staff: The vehicle will not relearn the battery on its own. You will have to use a BMW scan tool to register the battery. See this tech article:

http://www.pelicanparts.com/BMW/techarticles/BMW-3-Series-E90/BASICS-Battery_Connection_Notes_Replacement/BASICS-Battery_Connection_Notes_Replacement.htm - Nick at Pelican Parts
 
Eddie Comments: I have a 2007 325i e90, I had the engine light come on and was told the solenoid intake/exhaust valves were sticking. I had them replaced and now it runs rougher than before. I was told it takes sometime for the engine to readjust as it has to "re-learn" and the issue will disappear after driving for a few days. It runs very rough when idle. Does it need time to re-adjust? That does not sound right to me.
November 28, 2013
  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.
With that said, replacing the solenoids does not require a relearn as you are not changing a part that is monitored by a sensor. It is just a solenoid. You may have a problem with the VANOS actuators. - Nick at Pelican Parts
 
Jake Comments: I have an 05 bmw 645ci and I'm getting multiple cylinder misfire codes and failed o2 sensor codes. i have a very rough idle upon start on cold days which smooth out once the engine warms up. would this be related to the vanos in any way?
November 18, 2013
  Followup from the Pelican Staff: Not the o2 sensor codes. The rough running could be. I would start by looking into the fault codes for the oxygen sensors. They may lead you to the root cause. - Nick at Pelican Parts  
mike Comments: I have a 1997 bmw z3 2.8. Car threw a p1519 & p1525 code. I've looked on a million forums and everyone says something different. The car seems to be tip top. Plenty of power. I cleared the code and it came back on after the 2nd start. Any ideas? Thanks
November 5, 2013
  Followup from the Pelican Staff: Both faults a related to the VANOS system. Check the cam and crank sensors and teh vanos solnoids.
- Nick at Pelican Parts
 
Wayne Comments: I have a 2011 BMW 528i with about 70k miles. My vehicle was stalling like it was misfiring. Dealer tells me that my Intake Vanos needs replacement for $750. Wow this sounds like a lot. I'm just now investigating. Is this a DIY job for a novice? Thanks.
October 31, 2013
  Followup from the Pelican Staff: If they are talking about the solnoid itself, you can do it yourself, there is even instructions on our tech page.
- Nick at Pelican Parts
 
sn Comments: Hi, BMW 325i convertible. 70,000 miles yr 2008.
Recently i have started to get some problemw ith the car.when i start the machine.it trembles and have some difficulties..and the engine light remain on but after some 10 mins..when it warms up.it stops..but it does again and again when i start the machine when its cold..i have got it check at a mechanic and he passed it in a machine and gave a list that there are problem with 3 sensors and some misfire combustion but i doubt it. can you please tell me how to fix this problem.thanks
October 30, 2013
  Followup from the Pelican Staff: If there are faults stored for a faulty sensor, I would replace the faulty sensors and clear all of the codes and test drive it and recheck it.
- Nick at Pelican Parts
 
jounaid Comments: Im a mechanic and I need to know what the best scanner for bmw ?
October 27, 2013
  Followup from the Pelican Staff: This would be the BMW factory scan tool, or the Autologic scan tool. - Nick at Pelican Parts  
Aaron Comments: Hi, I have a '97 M3 with right around 70k miles on it and last week the check engine light came on with P0340 & P1519 codes coming up. It says this is a sensor issue but I doubt it is. What is the root of this problem usually and what can I do to fix it?
October 19, 2013
  Followup from the Pelican Staff: PO340 is for the cam sensor and p1519 is related to teh cam sensor, I would replace the cam sensor and clear the codes.
- Nick at Pelican Parts
 
ficky Comments: I have a e36 97model and was told the venos pump needsto be replaced, my problem I have is the car was running 100% and was standing for 3 days, when I started it one morning the car never wanted to start,I then inspected the plugs and found its full of oil,could this be the venos pump as the timing now is out
October 19, 2013
  Followup from the Pelican Staff: I would look to the oil separator for the reason there is oil in the motor. I would also check for bent connecting rods. The vanos unit shouldn't cause that problem.
Nick at Pelican Parts
 
JC Comments: How long should a VANOS solendoid valve last? My BMW x3 has 47,000 miles and BMW charged me to replace both of them.
October 8, 2013
  Followup from the Pelican Staff: I have seen cars that they have failed at less than 10,000 mi and also cars that they have never failed.
- Nick at Pelican Parts
 
Bargain Bob Comments: Would a bad vanos solenoid cause high oil consumption on a 2006 Mini? No turbo. Oil is disapperaring, no apparant leaks and no smoke. 4 qts in 2000 miles and 90,000 miles on car
September 26, 2013
  Followup from the Pelican Staff: Unfortunately no. If your engine is losing oil and there are no external leaks, you are likely burning it. Check that the crankcase breather and valve cover are OK. - Nick at Pelican Parts  
sal Comments: hi!. on my 2000 M5, i fund out what is my problem,one of the four solenoid is bad and i need to know where i can buy it?
July 21, 2013

Give our parts specialists a call at 1-888-280-7799. They can help you find the right part.
- Nick at Pelican Parts
 
sal Comments: i have a 2000 BMW M5 v8 and i have a solenoid banus problem can someone tellme how to fix or where i can buy those parts?
thank-you in advance
July 17, 2013
  Followup from the Pelican Staff: Without knowing your symptom or fault codes I cannot offer much help. Is the solenoid faulty or the actuator? Once you determine which one is bad, you can replace it. Very rarely are both faulty.

Give our parts specialists a call at 1-888-280-7799. They can help you find the right part. - Nick at Pelican Parts
 
tonythomas33 Comments: Hi i have a e36 323i and it has got lumpy tick over bad fuel consumption and lack of torque in lower gears and it can judder but no loss of power as soon as you touch the acclarator it drives normal.had it on computer and it said vanos mecanical faliure ive been told it could be the vanos solenoid or camshaft position sensor ive got no sounds coming from the vanos at all im sort of stuck dont want to be buying parts for no reason any ideas.

July 2, 2013
  Followup from the Pelican Staff: the noise could be the VANOS actuator, especially if you have rough running and a fault code to go with it. if the problem is worse when cold, suspect the VANOS actuator. - Nick at Pelican Parts  
Sonny Comments: My BMW 328i needs the VANOS solenoid changed. The car has fuel issues when I bought it. By the way I bought it new. I took it back to the dealer several times to complaint about the about of gas the car consumed. It was getting far less gas mileage that was suggested. Did BMW have a recall on this item? I went to a BMW service clinic and many of the customers were having this same problem.
May 14, 2013
  Followup from the Pelican Staff: Fuel mileage changes due to many factors. Driver habit, enviroment, fuel quality and additives, etc.

If the engine is running well and the check engine light is not ON, I would assume your engine is running well. If so, then your are likely getting the fuel economy you should be. - Nick at Pelican Parts
 
Sam Comments: Can you please post how to change VANOS solenoid on MINI cooper s R56. Thank you in advance.
February 27, 2013
  Followup from the Pelican Staff: if I get the chance to performthe repair I willbe sure to document it. - Nick at Pelican Parts  
Mike Comments: I have a BMW 328i that I don't drive very far each day, it only has around 44,000 miles on it. My extended warranty just rand out a couple of days ago. Two nights ago I started the car because I was cleaning the inside and it was cold outside. About a minute into the idle it started idling really rough and jumps and almost stalls when I put it in reverse. There is a check engine light on and there is also a noticeable loss of power. Everything was fine before, except for the fact that I had to replace a tire that could have easily been patched because it was a run-flat and that was not covered by the warranty, so I had to pay $350.00 for a new tire.
January 31, 2013
  Followup from the Pelican Staff: Sorry to hear about the cost of replacing the tire. A lot of people get rid of the runflat tires because they are so expensive to replace when they get damaged or worn out. As for your fuel injection issues you need to get a good code reader and read the codes that the computer is outputting. Any other work is just guesswork, and you really can't easily solve fuel injection problems in this manner. The code reader I recommend is the PEAKE research reader that should work on all BMWs. In many cases it's an easy fix and the codes would say exactly what's wrong. I have a tech article on this procedure as well in the main tech article section. - Wayne at Pelican Parts  
Martin Comments: What is the size of the sealing rings for the VANOS solenoid oil supply line? I can't figure it out and don't know where to buy them?
January 24, 2013
  Followup from the Pelican Staff: Give our parts specialists a call, they will help you find the right part: 1-888-280-7799 - Nick at Pelican Parts  
MGregory Comments: Hi Wayne,
My car was bought after an engine change and I cannot locate the correct plug for the VANOS Solenoid. Can you tell me where the wire that goes to it is located. NOTE: there is no connector next to the oil filter.
I am getting the following codes from the PEake Tool I purchased from Pelican:
3E, 15, D4

RP DIDDY Comments: Paid $1,800 for extended warranty and 2 months out, I too am being told that I need to replace the vanos solenoid on my 75,000 mile 2007 X3. I also have an X5 with the same problem at around 80,000 miles. Is this so normal for BMW. If so, why the hell are we buying BMWs. Oh, BTW, in addition to the solenoid, the car was brought in for a stuck thermostat which also requires an electric coolant pump. Cost for that.. a whopping $1,100. Let's not overlook the 2 washer fluid pumps at $190. Isn't ironic that when my BMW was in there during the warranty period, none of this was found and now 2 months later, everything needs replacing... Last BMW I'll ever own.

  Followup from the Pelican Staff: VANOS solenoids can become dirty and then function decreases. Maintaining long term performance is dependent on lubrication system maintenance. I suggest changing your engine oil every 5,000 miles.- Nick at Pelican Parts  
shachanic Comments: Hi, was just told at the BMW dealer that my BMW x3 has an oil filter leak, vanos feed is also leaking, need valve gasket cover. Cost $1,300. I am still in shock.

Stevie Comments: To Jem, take no notice of the rip off dealers, with those codes just order both Vanos solenoids and fit yourself, so easy,takes no more than 10 minutes. Cost for the both with new "o" rings should be no more than $250

Shane Comments: Wanted to ask though hers leaks oil at the sealing ring im going to tackle this this weekend but when she hits about a qt low the car wont start or starts then stalls immediately and the fuel line to the rail gets over loaded with pressure. put oil in it and start it as if it were flooded and she runs beautifully. my question is does anyone know if this is a common lack of pressure problem or possible the tell tale signs of a dying vanos unit?
June 15, 2012
  Followup from the Pelican Staff: It could be a failing vanos unit, unplug both vanos solenoids and see if the problem goes away, if so replace the vanos.

Legendary410 Comments: I have a 2003 BMW 325i that i am having my " mechanic " put in a head kit due to a bad head gasket. My problem is that there is a special socket to remove the head bolts and its the only tool I'm missing. Where can i get one and what is it?

JEM Comments: BMW 335i - we took our 2007 in for a recall notice on the fuel pump a couple of months ago and had it replaced. All of a sudden now the vehicle's motor light is on again. Took it to BMW dealer and they said that now we need to pay $950 for vano solenoid and possibly a cam shaft, which would be additional. Can I replace this on my own without taking it to the dealer if I am a novice? codes: 2A82, 2A87

Bimmer Bob Comments: Hi, yesterday I had my first rough engine startup E36 328ic 1999. Then recieved codes p1519 and p0340. I reset my engine light. I got the p0340 code again but no engine problems. Would you recomend I change the electronic sensor for the intake valve or the VANOS Selinoid? Which is most likely, and would the + or - 15% change in timing cause the engine to almost not start?

  Followup from the Pelican Staff: I would replace in intake cam sensor first, Give our parts specialists a call at 1-888-280-7799 and they can help figure out which part or repair kit you need.

Dave Comments: Hi there, I'm beginner in DIY stuff. I have a 325i BMW with a "service engine" light on my dashboard so I went to Autozone to get the diagnose done using their machine and they gave me a code "P0369" aaCMP sensor "B" intermittent interruption. They said that diagnose is not accurate since their equipment is not good for beemers. I want to repair the car myself so I dont know what to do know. Should I trust that code? or How/where can I get an accurare Diagnose? I'm trying to avoid buying the machine since I'm trygin to repair the car so I can sell it, Should I buy my own machine? What would be a good diagnose machine for BMW? Your guidance is appreciated. Thanks

  Followup from the Pelican Staff: That code is for a exhaust cam sensor, I would replace the sensor first.

Dave Comments: Yes you were right, it was stuck so I put more force on the tool and I was finally able to remove it. THANK YOU!! Btw: The wrench I was using was quite short so I found a tool with a LARGER handle with provides more leverage requiring less muscle...

Dave Comments: I cant remove the VANOS unit solenoid on my 325i-BMW-01man its soo tight that appears that it was welded...and obvioulsy I know it wasnt... Im using an adjustable wrench turning clockwise looking from the front of the car. Dont want to brake it....Should I just keep trying orI'm I missing somenthing?
August 21, 2010
  Followup from the Pelican Staff: Clockwise should be correct, if it's turning, it may just be stuck, but I can't be 100% sure without looking at it in person. - Wayne at Pelican Parts  
e Comments: hey thanks Wayne i appreciate it alot

e Comments: I'm changing my camshaft sensor, i know that i need to take the vanos oil line off and also i know that i need the sealing rings but do i need to change the banjo bolt too?
April 27, 2010
  Followup from the Pelican Staff: Nope, it's perfectly fine to reuse the bolt as-is. - Wayne at Pelican Parts
