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.

STEERING ASSISTANCE SPORADIC REDUCTION: The driver notices a reduction of steering assistance sporadically while in certain driving situations. Steering control is never lost when the reduction of assistance occurs.
