Description
Used original Bosch engine ECU for Volkswagen Polo 6N 1.0, supplied under primary OEM number 0261203744 and alternate number 030906026AK. This control unit is a genuine factory electronic module designed for the vehicle named above and is intended as a direct replacement by exact part-number match.
The engine control unit manages core engine functions by processing sensor inputs and controlling fueling, ignition, idle behavior, and overall engine running strategy. It is a central part of the engine management system and helps the vehicle start correctly, run smoothly, and maintain stable performance in normal driving conditions.
Common signs of a faulty unit include non-start conditions, intermittent starting problems, poor idle quality, hesitation, misfiring, uneven throttle response, warning lights, or communication faults during diagnostics. Electrical issues inside the ECU can also lead to erratic engine behavior that is difficult to trace to other components.
This is a used original part, removed from a vehicle and tested before sale. Please match 0261203744 and 030906026AK exactly before ordering. Professional installation is recommended, and coding, programming, or adaptation may be required depending on the vehicle setup and repair 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.
