Description
Bearing OEM number 7798422, this Engine ECU Control Module was produced by BMW specifically for the E60 5 Series platform. Drawn from a written-off vehicle with documented mileage and passed through comprehensive diagnostic testing, this genuine used unit is a dependable replacement for a failing E60 engine management module.
The E60 5 Series ECM synchronises fuel injection phasing, ignition advance mapping, throttle position control, and catalytic converter warm-up management across the full engine temperature cycle. Inputs from the mass airflow sensor, crankshaft encoder, and post-catalyst oxygen sensor allow the module to make real-time corrections that preserve both performance and emissions compliance.
Loss of ECM performance in the E60 5 Series often declares itself through increased fuel consumption, rough idle, misfires on one or more cylinders, and a check engine warning that cannot be permanently cleared. Extended crank time before starting, abrupt power cutbacks under load, and fault codes referencing fuel system or ignition channel deviations are also common indicators.
Supplied as a used, tested unit — confirm OEM reference 7798422 matches your E60 build and engine variant before purchasing. Professional installation is advised, and coding or DME adaptation will be required following fitment. Returns are accepted within 14 days.
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.
