crooked belt tensioner??
was wondering what can happen if i have a "crooked belt tensioner"? i have a '06 330i, and the car runs great. Starts up without problems everytime, no strange noises, runs perfectly. But I took it for an inspection recently (independent BMW mechanic) and was told that I have a "crooked belt tensioner". What types of symptoms, if any, should i expect to see from this? What can happen if I do not get this fixed asap? How can i check and verify this myself?
