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.
SERVICE ACTION: CHECK THE EXHAUST CLAMPS AT THE CATALYTIC CONVERTERS (F90): The screw clamps that secure the upper and lower catalytic converters (1) may loosen over time.
