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.
THE MIL IS ILLUMINATED WITH OXYGEN SENSOR FAULTS STORED: One of the following faults may be stored in the digital motor electronics (DME) either as part of diagnosing a different issue; and/or an illuminated malfunction indicator lamp (MIL).
