Ok, I'll ask: what are the symptoms of the vanos failure (other than the chain break described above which I assume is an extreme case)? Loss of power? Is there a way to check w/o having to take it to a dealer or someone with a GT-1 computer?
ON EDIT: read the first linky in the first post (second one led me to a discussion on 20" wheels). Seems something breaks in the vanos, f's stuff up, car starts to run rough and/or quits running, and a service engine soon light comes on. There also seems to be anectdotal evidence that this is tied to an Inpection 2 (valve adjustment).
Of course the 6yr/100k warranty on my wife's M3 engine has run out now...
Thanks for the info!
