I WAS TOLD THE ASSEMBLY WAS WEARING OUT AT 30K
WHAT YEARS DID BMW HAVE WEAR PROBLEMS WITH THE VARIABLE VALVE TIMING, on 2006 BMW M3
If this question isn't answered here it may be best to post on a BMW specific car forum. 30k sounds way to low to expect such wear. I see one Service Bulletin for your engine that may be relater I'll send it to the email you posted this question from.
THANX FOR REPLY. YES I SUPPOSE I COULD GET IN TOUCH WITH ONE OF THE MECHANICS WHO WORKED ON THEM .
