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.
Noise is heard from the seat frame/rail assembly. Noises may occur dynamically (creaking/knocking) when weight is shifting upon the seat Noises may also occur when activating the seat motors.
