Description
Used original Bosch engine ECU for VW Passat 35i, supplied under OEM number 0261200261 with alternate reference 443907311B. This control unit is designed for the Volkswagen application named and is an original electronic engine management component removed from a vehicle.
Its job is to manage core engine functions by processing sensor signals and controlling fuel delivery, ignition timing, and other key running parameters. A properly working ECU helps the engine start correctly, idle steadily, respond cleanly to throttle input, and maintain consistent overall drivability.
Common signs of a faulty unit include no-start or hard-start conditions, uneven idle, misfiring, hesitation under load, poor throttle response, and intermittent engine running issues. In some cases, communication faults, stored engine management errors, or injector and ignition control problems can also point to ECU failure.
This is a used original part, removed from a vehicle and tested before sale. Please match 0261200261 and 443907311B exactly before ordering. Professional installation is recommended, and coding, programming, or adaptation may be required depending on the vehicle setup and replacement procedure.
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.
