Description
Carrying OEM number 7785098, this Engine ECU Control Module was built by BMW for the E46 3 Series — a benchmark in precision German engineering. Pulled from a low-mileage written-off donor, this unit is genuine, used, and individually tested prior to sale.
At the heart of the E46’s drivetrain management, the ECM processes real-time data from the crankshaft position sensor, mass airflow meter, and oxygen sensors to optimise fuel injection pulsewidth and ignition advance. Accurate throttle response and exhaust emissions compliance depend entirely on this module performing within specification.
Deteriorating ECM function in the E46 3 Series typically surfaces as rough idle, unexpected misfires, and a persistent check engine warning. Drivers may also experience difficulty starting in cold conditions, noticeable power loss under load, or the vehicle entering limp-home mode with stored fault codes.
Sold as a used, tested unit — confirm OEM number 7785098 matches your vehicle before ordering. Professional installation is strongly advised, and coding or adaptation to your vehicle’s DME may be required after fitting. A 14-day return window applies.
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.
