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+

Same problem. I always thought it was from my tires not being warm and/or gripping the pavement.
This happens almost exclusively when turn right, particularly in parking lots and underground garages. Has anyone else experienced this with under 25k miles?
