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.
BUTYL ON ROOF AROUND REAR SUNROOF GLASS. CAUSE Exposure to normal ambient heat can cause the factory-applied sunroof butyl to expand and leak out from around the rear sunroof glass.
