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.
DME FC 20E120 IS STORED AND THE MIL IS ILLUMINATED: This Service Information Bulletin (Revision 2) replaces SI B12 18 18 dated July 2018. The Malfunction Indicator Lamp (MIL) is illuminated and the following fault code is stored in the Digital Motor Electronics (DME).
