BMW 7 Series: Other

Affects BMW 7 Series · 2002–2003 — about 35 vehicles.

The hazard

On certain 745I and 745LI vehicles, due to a software error in the digital engine management control unit, a desynchronization of the valvetronic motors for engine banks 1 and 2 may occur causing a rough-running engine. If this happens, the check engine light will illuminate, and the message "engine malfunction, drive with moderation" will appear in the vehicle's instrument cluster message display area. In certain extreme cases, the engine could stall and the driver may not be able to restart it. Correction: Dealer will reprogram the digital engine management control unit.
