Description
OEM number 1740354. This genuine BMW engine ECU control module fits the E34 5 Series and E36 3 Series. Removed from a low-mileage written-off vehicle, this unit is an authentic manufacturer-original part, supplied used and fully tested.
The engine control module manages fuel injection timing, ignition sequencing, and emission controls across the operating range of the engine. It processes data from sensors including the crankshaft position, mass airflow, and coolant temperature sensors, coordinating outputs to injectors and ignition coils to maintain efficient combustion and smooth power delivery.
A failing ECU may cause the engine to crank without starting, trigger persistent fault codes on diagnostic equipment, produce rough idling or misfires, or result in sudden stalling under load. Erratic throttle response and poor fuel economy are also common symptoms of electronic control module failure.
This unit is sold as a used, tested part. Always confirm that OEM number 1740354 matches your vehicle before ordering. Professional installation is strongly recommended. ECU coding or adaptation to the receiving vehicle may be required. A 14-day return period 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.
