I have a 2008 335i (02/2008 build) and over the last 6 months my car has been louder while idling (squealing noises). I have about 52k miles which in my opinion is not a lot.
I think it is from the belts. I looked at them they seemed tight with "good" groves. After reading this thread I am getting the feeling that I am on the "brink" of possible disaster. I am out of warranty and no CPO.
Please advise? Should do I change the belt? idler/pully? What to do inspect without any repairs?
