BMW service bulletin · NHTSA ID 10228424 · Nov 2022 · also written SI B12 02 22, B120222
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.
A fault in the diagnostic function of the spark plugs may result in an erroneous Check Control (CC) messageand fault memory entry.
