OEM number 7794904 references this Engine ECU Control Module, built by BMW for the E65 7 Series — the marque’s flagship executive saloon and the pinnacle of the BMW model range. Sourced from a written-off donor and fully verified through diagnostic testing, this genuine used module is prepared for professional installation in the flagship 7 Series.
Engine management in the E65 flagship demands exceptional precision: this ECM coordinates fuel injection mapping, ignition timing, variable valve lift actuation, and exhaust gas recirculation across a large displacement engine designed for effortless high-speed performance. It communicates with the E65’s sophisticated iDrive and CAN network to deliver seamless integration between drivetrain, comfort, and safety systems.
ECM issues in the E65 7 Series can manifest as loss of the smooth power delivery expected from a flagship BMW, rough idle, cold-start hesitation, and an illuminated engine management light logging fault codes related to fuel trim, sensor circuits, or timing system discrepancies. Limp-home activation or unexpected stalling can also indicate module degradation.
Sold as a used, tested part — always confirm OEM number 7794904 corresponds to your E65 engine and gearbox specification before ordering. Given the complexity of the 7 Series electronics, professional installation by a BMW specialist is essential, and coding or adaptation will be required post-fitment. A 14-day return policy is offered.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
