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.
Fault Code 121001 Stored in RDME. The Check Engine light (CEL) is illuminated in the instrument cluster and fault code 121001 "Catalytic converter: Efficiency too low" is stored in the RDME. This fault could occur during the initial REx engine operation cycle.
