Description
This is a used original Bosch engine ECU for VW Polo 6N, supplied under OEM numbers 0261203914 and 030906027P. It is the main engine control unit for the vehicle’s management system, built to work with the factory electronics and sensors used on this Volkswagen application.
The ECU processes signals from key engine sensors and controls functions such as fuel delivery, ignition timing, idle behavior and overall engine running. It is a central part of the engine management system, helping the vehicle start correctly, respond smoothly and maintain stable performance under normal driving conditions.
Common signs of a faulty unit include non-starting, intermittent starting, rough idle, poor throttle response, misfiring, hesitation, warning lights or communication faults during diagnostics. In some cases, an internal ECU fault can also cause irregular engine behavior that is difficult to trace to sensors or wiring alone.
This is a used original part, removed from a vehicle and tested before sale. Please match 0261203914 and 030906027P 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.
