We have classified the 1 complaints from 2001 BMW M3 about POWER TRAIN into the following categories.
Inspection by two mechanics shows cracks in the subframe holding the back wheels. there was a legal case involving this defect that was settled by bmw which was to fix the problem and notify all owners of 3 series bmw's about the defect so it could be fixed. they never informed me of defect and have staled on the repair.
My m3 cic makes a loud grinding/clatter type noise when disengaging the 6-speed manual clutch in both 1st and reverse. this happens when the car is moving at about 1-2 mph. bmw tech's say this is normal operation, however, i can't duplicate the same problem on a new m3 w/6 speed transmission. *jb
