Descrizione
This Bosch engine ECU is an original Volkswagen control unit for VW Passat B3 and Golf applications. The primary OEM number is 0261200271, with alternate reference 443907311D. It is the main electronic unit that manages essential engine operating functions and supports stable running, correct fuel delivery, and consistent ignition control.
At the heart of the engine management system, this ECU processes signals from key sensors and adjusts fueling and ignition strategy to keep the engine responsive and efficient. It helps coordinate starting, idle behavior, throttle response, and overall drivability while maintaining the correct operating balance under changing conditions.
Common signs of a faulty unit include non-starting, intermittent stalling, rough idle, poor throttle response, misfiring, uneven power delivery, or communication faults during diagnosis. In some cases, the engine may crank normally but fail to run correctly because the control signals are no longer being managed as intended.
This is a used original part, removed from a vehicle and tested before sale. Match 0261200271 and 443907311D exactly before ordering. Professional installation is recommended, and coding, programming, or adaptation may be required depending on vehicle configuration and workshop procedure.
