Description
Part number 030906026C is a genuine <a href="/brand/volkswagen“>Volkswagen engine control unit for small-capacity petrol engines — typically fitted to Golf and Polo variants — sourced from a running vehicle and individually bench-tested.
This ECU controls the core petrol engine management loop, including multi-point injection firing order, ignition timing, idle air control, and exhaust oxygen sensor feedback, maintaining the correct stoichiometric mixture and spark timing at all engine speeds and loads.
A faulty ECU on this platform often presents as an engine that starts and stalls, a persistent rich or lean condition causing high fuel consumption or black smoke, misfires on one or more cylinders that follow sensor replacement, or fault codes pointing directly to ECU output or communication faults.
Supplied as a used, tested OEM part to the original factory specification. Professional installation is recommended and VCDS or a compatible VAG tool may be required to complete adaptation.
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.
