VANOS Adaptation Values

[Arinb12]

I had CSL cam offsets which caused a code and failed vanos test post-tune. Read back in this thread, Martyn explains how to change CSL offsets to US.

But, I'm in EU, does the EU have different offsets to US standard?

I do not believe that is the case, to my knowledge it's either CSL cams, or what I've called "US cams", but a more accurate description would be "non-CSL" cams.


I would check your offsets, see if they are what mine turned out to be (CSL), if they are wrong changing them is easy. If you can view your offsets your 80% the way there to changing them.

I have done VANOS work on the Z4M twice, and never had to reset adaptions, but we have different ECU's

I just pulled adaptation values. Could not get the oil up to full temp because track car. 170 is about as high as it gets idling and 45 degrees outside.

Looks like I’ve got some pretty good numbers! I better since I retimed it 5 times.

But aren't the adaptation values just stored from the last time the car was driven?

I think only the actual vanos test should be done on a warm engine. The adaptation values can be retrieved at any point in time.
