Description
Used original engine ECU for VW Polo and Seat models, built by Marelli and identified by OEM number 6K0906030D. This control unit is part of the engine management system and is designed for the vehicles named above, making it a direct OEM electronic component for the correct application.
The engine ECU processes signals from key sensors and manages fuel delivery, ignition timing, and other core engine functions. By coordinating these inputs and outputs, it helps the engine start correctly, run smoothly, and maintain stable performance under different driving conditions.
Common signs of a faulty unit include non-starting, intermittent starting problems, misfiring, poor throttle response, uneven idle, warning lights, or communication faults during diagnostics. In some cases, an ECU issue can also lead to inconsistent engine performance or unexplained running problems.
This is a used original part removed from a vehicle and tested before sale. Please match OEM number 6K0906030D before ordering. Professional installation is recommended, and coding, programming, or adaptation may be required depending on the vehicle setup.
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.
