What it covers
A service bulletin tells BMW technicians how to diagnose or fix a known issue. It is not a recall: a repair under a bulletin is normally paid by the owner unless the car is still under warranty or a warranty extension applies.
LEAKING REAR DIFFERENTIAL (QMVH): There is an oil leak from the rear differential housing.
