Description
This is a used original Bosch engine ECU for VW Polo and Seat Ibiza applications, carrying primary OEM number 0261203750 and secondary reference 6K0906026B. It is the main engine control module responsible for managing key running functions in compatible petrol engine systems.
The ECU processes signals from engine sensors and adjusts ignition timing, fuel delivery, idle control and other core parameters so the engine starts, runs smoothly and responds correctly under load. It plays a central role in overall drivability, emissions control and stable engine operation.
Common signs of a faulty unit include non-starting, intermittent stalling, misfiring, poor throttle response, uneven idle, loss of power or persistent engine management faults. In some cases, communication errors during diagnostics or recurring sensor-related fault codes can also point to ECU failure.
This is a used original part, removed from a vehicle and tested before sale. Please match 0261203750 and 6K0906026B 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.
