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.
REVERSING ASSISTANT LIMITATIONS: The Reversing Assistant function is not operating to customer expectations. Some possible customer concerns are: Vehicle does not avoid objects in its path tires or wheels contact the curb reversing Assistant only works for a short distance.
