Description
OEM number 7803369 identifies this Engine ECU Control Module, factory-fitted by BMW to the E60 5 Series executive saloon. Taken from a written-off vehicle and passed through a rigorous functional test, this genuine used module offers a cost-conscious alternative for E60 owners facing engine management failure.
In the E60 5 Series, the ECM is responsible for orchestrating fuel injector activation, spark advance curves, idle speed control, throttle-by-wire positioning, and secondary emissions management. It interfaces with the E60’s CAN bus to share torque and load data with the automatic gearbox controller and stability management system, ensuring cohesive drivetrain behaviour.
ECM failure in the E60 5 Series frequently presents as uneven idle, reduced performance, hesitation when pulling away from standstill, and engine warning lights accompanied by fault codes relating to fuel trim limits or ignition circuit errors. Intermittent stalling and failure to start from cold are also characteristic of a compromised module.
Sold as a used, tested unit — verify that OEM number 7803369 is appropriate for your E60 engine variant before purchasing. Professional installation is strongly recommended, and the module will require coding or adaptation following fitment. Returns are accepted within 14 days of delivery.
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.
