BMW 640i convertible 2011 - Rear whine - Hugh Williams

I have recently noted a whining type drumming coming from the rear of the car that intrudes on the usual quietness of the car which has done 56000 miles. I thought it may be a wheel baring but one going could nt be detected and the mechanic is nt sure what it is! Any ideas?

Your wife isn't sitting in the back seat is she?

I'd be surprised if the diff was away at that mileage or even a wheel bearing, though it is a possibility. Possibly sticky brake calipper? You really need to take it to someone who understands these cars to have it properly diagnosed.

Was it sourced from a BMW main dealer with full BMW service history? These are complex high value cars that require main dealer or genuine specialist servicing. Plenty of them have been crashed and poorly repaired and clocking is still an issue.
