Description
This is a genuine Bosch engine ECU for the VW Polo 6N 1.0, supplied under primary OEM number 0261203744 and alternate reference 030906026AC. It is the main engine control unit for this Volkswagen application, designed to manage the core running functions of the engine and support stable day-to-day operation.
The ECU processes signals from key engine sensors and uses that data to control fueling, ignition timing, idle behavior, and other essential management functions. A healthy unit helps the engine start correctly, run smoothly, respond cleanly to throttle input, and maintain proper overall drivability.
Common signs of a faulty unit include non-start or intermittent starting, poor idle, misfiring, hesitation, unexpected stalling, loss of power, or warning light issues linked to engine management faults. In some cases, communication problems during diagnostics or irregular running behavior can also point to ECU failure.
This is a used original part, removed from a vehicle and tested before sale. Please match the exact OEM number 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.
