I could really use some advice with my 08 535i. I start the car and it rough idles for a few seconds then it dies. I start it up again and it may repeat this process for a few more times before i can actually drive it. I made it out to the dealership and they took me for a ride by charging me 200 bucks to mess with the software. They made mention of the VANOS solenoid as the potential root cause. After reading a few threads i have a feeling this is more than likely my issue.

First and foremost what is the function of this solenoid?
How easily can this part be replaced?
Is there a decent walkthrough to replace this part available on the forum?
Is replacement necessary or can this part be cleaned and/or adjusted to rectify the problem?

Thanks in advance for the help.

The dealer first step is to clean the solenoids so you can try this too. They can be cleaned with air gun and brake cleaner.

I am 3 hours north of you if you want to make a trip. I can show you what and how to do it. Look at the computer codes too.

Just curious...how many miles? How many fuel pumps so far? Any injector replacements in the past? If high miles, it could be the dreaded carbon buildup issue that is becoming a more frequent topic as the miles accumulate on board members' cars. You've probably found the answer to your issue, but just playing Devils advocate...

No, those are all valid points actually. It has just over 55k on the odometer. 2nd fuel pump and no new injectors to my knowledge (2nd owner). Currently it sits at the dealer so i should know more tomorrow.

Ha! So what an affair that all turned out to be. After the software failed to cure the problem, the dealer set thier sights on replacing the low pressure fuel pump. 700 bucks later i pick up the car and fill it up the next day only to watch the gas pour all over the concrete. I had them tow it back to fix it correctly and get it back only to have the engine die again! The dealer picks the car up again and says its a low pressure fuel sensor. By this time they insist the repair is on the house and i insist that not only is it on the house, the money paid out is to be fully refunded and they needed to install the new aftermarket pads and rotors that have been waiting to get installed for several weeks if they ever want my return business. Amazingly they did all this no questions asked! I would recommend them over the indy shops in my region only for the fact that bitching about their incompetence gets you the hook up if played properly.

Hello people, got two problems which I have been told are common on 2005 bmw 6 series (E63).
1. Seat restraint waning and airbag from now where after the car wash people disconnected the socket, I tried clearing from the garage computer. but eventually comes on. : (
2. Vanos intake problem. been told its common too. my 6 has now done 103000 and now all of a sudden making knocking noise and feels like its gonna cut off while driving.
tried asking some of the so called BMW specialists all they talk is 1000s and now it has put me off even touching the car,
any suggestions fellows???
