I have 2001 Z3 coupe, automatic with 30 k miles. For several years I have been hearing a squeal coming from the rear of the car. The squeal will often appear during a sharp turn, usually to the right and on acceleration from low speed. The car will squeal for a few days and then stop for a week or so until the next episode. When reaching about 55 to 60 miles on the speedometer the squeal will be continuous until the speed will increase or drop from that speed range.

I have been unable to demonstrate the squeal to BMW dealerís mechanics. The car refuses to produce the squeal when they are in the car. I am not sure if the car has to be warmed up for the squeal to appear. Is anyone having a similar problem? Thanks.
