i will be ordering soon,

the DIS (GT1) states that all adaptations on the ECU should be reset after a vanos replacement among other repairs it lists.. you guys might want to have your adaptations reset next time your at the dealer or find someone with the capability (im not referring to the throttle adaptaion, the entire ECU adaptaions)

Well, I have been having the idle issue during warmup in cold weather. I just ordered a set and plan on starting on this in a few weeks. Thanks for all the hard work in sorting out a solution Rajaie!

My 2002 320I has about 60K miles on the clock and is there anyway to test if you got a failing VANOS with a step transmission?

Everything seems fine. However about 2-3 times for this cars life whenever I approached a stop it had a jolt of power loss and almost stalled. That happened rarely though and at first though I though it was the transmission.

An owner recently noted that after performing the vanos seals repair this symptom went away. He also said it did not happen often. I was not aware of this symptom.

All M52TU/M54/M56 engine cars have this double vanos and have failing vanos seals. The seals are significantly failing in 20k miles. Your's are significantly damaged. Every owner that has replaced their vanos seals has reported significantly damaged seals. The O-rings are made of Buna and this material is completely not compatible with the engine environment.

Adaseb. I have a steptronic transmission. I don't know if your engine falls in the M52TU/M54/M56 series. I only notice the jolts and stalls on cold weather mornings, only if you let the car idle after you start it for more than 2 minutes. When it happened, i disconnected the vanos intake solenoid electrical connector, and the problem stopped right away (Turn off the engine before disconnecting). so try it.

Hey guys.. Are these the 15 grommets I need when replacing my Valve cover gasket?
http://www.rmeuropean.com/index.asp?...l=&strCompare=
My dealer has these for $3 a piece so these come to a hell lot cheaper even with international shipping. I have my seals laying around. It's just so cold I won't be attempting this for a while.

No you don't definitely need them, but I'd recommend replacing them.

You have nothing to worry about. You can only put the vanos back together correctly. You just can't make any mistakes. No one has yet. Once the vanos is closed up the procedure has you test the piston movements.

Installing the vanos back onto the engine head is also no problem. There are dowels at the top of the head that the vanos fits onto. There is nothing to do wrong, and no one has done anything wrong before.

If you have any questions or issues, call me at the phone number on the Beisan website.

Good luck.

Rajaie, I am thinking about doing this. I realize that you wrote no gains were present on the dyno. Any reason why this might be? Is it because once the seals heat up, they start "working" again? Just wish there was some way to know if was worth taking the whole vanos apart.
