Alternator belt/idler pulley failure on M4
See my post under the track/autocross section.
The idler pulley in my 2015 M4 failed, and took out the alternator belt, while on-track. Appears to be a potential issue popping up among a few cars. I have 12,000 miles on the car. BMW repaired (entirely) under warranty. |
