During tight, slow speed turning, a rubbing noise can sometimes be heard from the rear of the car. This noise is likely coming from the clutches in the limited slip differential. If the noise persists, the differential fluid can be replaced with a special oil available from BMW. On higher mileage vehicles, this noise may never be eliminated unless the differential is replaced.Google+

BMW did offer Goodwill Assistance for numbers 2&3 in the form of a 50% discount. Numbers 4&5 have yet to be fixed. I am waiting for BMW to offer assistance on this one as well. Don't know if it will happen. Anyone contacted their Attorney Generals for Consumer Rights Protection?
