Description
Original Magneti Marelli engine control unit ECU for Peugeot 405 and Citroën BX models. This is OEM number 16005, with Marelli G5.S0 as the matching hardware reference. It is the main electronic controller for the engine management system used in these vehicles.
The ECU processes signals from key engine sensors and manages fuel delivery, ignition timing, and overall running strategy. In daily use, it helps the engine start correctly, idle steadily, respond smoothly to throttle input, and maintain proper operating performance across normal driving conditions.
Common signs of a faulty unit include no-start or intermittent starting, unstable idle, hesitation under acceleration, misfiring, poor throttle response, or irregular fuel delivery. In some cases, the engine may run rich or lean, cut out unexpectedly, or show communication faults during diagnosis.
This is a used original part, removed from a vehicle and tested. Match OEM number 16005 and hardware reference G5.S0 before ordering. Professional installation is recommended, and coding, programming, or adaptation may be required where applicable for the vehicle system.
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.
