Description of your VANOS issue: SES code b8

How did you determine that the solenoid was the likely problem?:reading here

Did just a VANOS Solenoid swap fix your issue? NO!
SES Light On?:Yes

Fault Codes:b8, intake camshaft 1, Vanos position control
Model Year:2003

Mileage at time of VANOS issue:60104
If the VANOS Solenoid swap did not fix your issue, what did? To Be Determined

Other Comments (How did you make your decisions, words of advice, etc.): I did take the VANOS completely off to inspect. I replaced the cam gear bolts two yrs ago and they were still solid. Exhaust cam gear tabs/tangs were also intact and not broken. Also checked the camshaft timing and the cams were timed correctly. One thing I did notice was that the Vanos exhaust piston was firm when I pushed it in and out, but the Vanos intake piston just slid easily in and out. Maybe I have this code because the seals on the Vanos intake piston is bad? I will probably dish out the $1500 and replace the complete Vanos and sell the Vanos solenoid that I just bought for 1/2 price. PM me if you need a solenoid pack, I just bought it last week.

If you know how to remove your Vanos but mess up your camshaft timing PM me, you can time ur cams with no special tools.

What a dilema.....

Description of your VANOS issue: SES Light
How did you determine that the solenoid was the likely problem?: Searching Internet, PMing members, emailing Dr. Vanos
Did just a VANOS solenoid replacement fix your issue?: No
Did you use a New or Used solenoid?: New
If Used, how did you determine that it was fully functional?: NAP
SES Light On?: Yes
Fault Codes: Peake: B9 - Exhaust camshaft VANOS position control
Model Year: 2004
Mileage at time of VANOS issue: 43,000
If the VANOS solenoid replacement did not fix your issue, what did?: Indy shop replaced VANOS actuator with rebuilt Dr. Vanos unit and replaced exhaust camshaft position sensor at the same time. It's hard to say which part fixed the issue but my guess is that it was the actuator. I replaced the camshaft position sensor because my mechanic would do it without billing me additional labor costs.
Other Comments (How did you make your decisions, words of advice, etc.): Read all the VANOS threads here and consult Dr. Vanos. It can be difficult to determine exactly which VANOS component fails. I recommend starting with the lowest cost fixes first (solenoid, camshaft position sensors). If these don't work, then you'll have to try the more costly VANOS actuator replacement and pray that the VANOS oil pump driver prongs on the exhaust cam sprocket are not broken. If you have to remove the VANOS actuator, you should consider replacing the 12 cam gear bolts that are known to fail (but only by a competent mechanic using the special BMW tools).

BTW, I still have my old solenoid that probably still works for sale: http://www.m3forum.net/m3forum/showthread.php?t=334899.

What are early signs or symptoms of a deteriorating VANOS? Aside from the everyday wear and tear and years of attrition, will high revved driving accelerate or induce early failure? The X5 with sunroof leakage, the 535i with HPFP issues--on my 2nd, and now the potential VANOS failure...talk about job security for the BMW techs.

Default Re: Did a VANOS Solenoid Swap Fix Your VANOS Issue?

Description of your VANOS issue:
My car was running rough at idle. Huting idle at warm up. Very little power. My first guess was cylinder misfire. My SES light turned on and i ready the codes with my peake tool:
1b= table b
b8 = intake camshaft vanos postion and control
cd, ce, cf, do, d1 d2,d5 = misfire during warm up cyl #1 to 6 and misfire during warm up mulitple cyl.


How did you determine that the solenoid was the likely problem?:
peake codes

Did you run a VANOS test? NO. If so, what was the result and codes?
Did just a VANOS solenoid replacement fix your issue?: YES
Did you use a New or Used solenoid?: Used
If Used, how did you determine that it was fully functional?: installed it and fixed my problem
SES Light On?: not any longer
Fault Codes:
Model Year: 2001
Mileage at time of VANOS issue: 54k
If the VANOS solenoid replacement did not fix your issue, what did?:
Other Comments: After doing much research I was 95% certain it was the vanos solenoid. There were concerns that it may be the intake or exhaust camshaft sensor but my peak tool did identify those specific codes. Had the solenoid not worked I would have assumed it was the complete VANOS.

Ses light on, sometimes will off for a day and it will come back. No strange symptom for 2 weeks then it knocks and shake, won't run after that.

Initially throw p0014 exhaust camshaft over advanced, then it started to misfire all 6cyclinders and won't run.


How did you determine that the solenoid was the likely problem?:
Obd2 code + BMW inpa, lot of research and by logic, solenoid gets sticky overtime, and symptom get worse and worse kindda indicating solenoids got stickier and stickier
Did you run a VANOS test? NO. If so, what was the result and codes?
Did just a VANOS solenoid replacement fix your issue?: YES
Did you use a New or Used solenoid?: New

Description of your VANOS issue: Throwing Codes...
P0013 Camshaft Position Actuator B - Bank 1 Circuit Malfunction
P0014 Camshaft Position Actuator B - Bank 1 Timing

How did you determine that the solenoid was the likely problem?: Took to Indy shop, they had seen the problem and tested it, it failed.

Did just a VANOS solenoid replacement fix your issue?: Yes

Did you use a New or Used solenoid?: New

SES Light On?: Yes

Fault Codes: 0013, 0014

Model Year: 2002

Mileage at time of VANOS issue: 111,000

Other Comments (How did you make your decisions, words of advice, etc.): I was just hoping that it was only the solenoid throwing the codes and I wouldn't have to get work on my Vanos.

I also got a valve adjustment, complete Inspection 2 fluid change, and went catless at the same time so my baby is loving life.

I have the exact same problem & the exact same year with nearly identical Peake Codes. I'm talking to Raj @ Beisan Systems about a reman solenoid pack. I'm hoping this fixes the issue.

2001 M3
71k miles
recently did my own valve adjust (very easy just time consuming)
Had these same symtoms you're having since 65k been beating around the bush trying not to fork out for a new vanos. Here's hoping
