Have not started the car yet. Instead I did the ignition on /off cycle a few times and noticed the servomotor initial adjustments are quite noisy and noticeable. (Compared to the old servomotor).





The click sound upon turning on the ignition is, I think, the adjustments. The sound afterwards, is still the same sound I could hear when the old servomotor was installed. The second sound is like the camshaft returns back to its point, therefore skipping the wormgear teeth.


Is this normal?!
I believe there is a programming procedure when you replace the VVT. It sounded like it did rotate correctly at first, but then I definitely hear some sort of grinding.
I went back and watched the startup videos I'd recorded with the old servomotor, and noticed similar noises! Maybe the new one sounds a little louder.

This is a tough one. How does the car drive with the new VVT? How many miles are on the car?

I haven't driven it yet myself. But according to my wife, there was a bit of hesitation.

94 k miles.

The clunk was very substantial and loud yesterday.


No clunk this morning. I might start parking the car with front-in, instead of rear-in.

If things improve by parking rear side inclined, then this is a not the camshaft issue. I will try getting a diagnosis from a BMW indy shop.


My last solution will be to rid myself of it. Costs once, but man, I cannot afford working on it!

It's the 6hp19 clunk!

Turns out it's not the engine, it's rather the self-checking mechanism of the Automatic Transmission 6HP19!

This SIB instructs dealers to reprogram the EGS module (or EGS and CAS) for this specific clunk.

Many dealers have sent owners back that this is normal! There is no cure for this!!

So, did you reprogram it?
