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.

Cracking in Rear Differential Mount Bushing. During inspection, the rear differential mount in the rear axle support shows signs of cracking.
