Description
Part number 030906027AH is an OEM engine control module for the <a href="https://giantparts.eu/brand/volkswagen“>Volkswagen Polo and Golf small-displacement petrol range — dependable and efficient compact hatchbacks that defined accessible motoring across the VAG A2 and A3 model generations. Removed from a running vehicle and tested, this genuine used unit provides OEM-quality engine management.
The ECM handles fuel injection and ignition control for these small petrol engines — managing injection timing and quantity, ignition advance curves, idle speed stabilisation, cold-start enrichment, and closed-loop lambda feedback for efficient, low-emission combustion aligned with VAG’s calibration.
Common symptoms of ECU failure on Polo and Golf small petrol models include hard starting, rough idle, engine stalling, flat spots during acceleration, poor fuel economy, and stored fault codes relating to injection signal faults, lambda circuit errors, or idle control anomalies.
Supplied as an OEM-matched, tested used unit for Volkswagen Polo and Golf petrol applications. Professional fitting is advised; VAG diagnostic coding and immobiliser adaptation may be required after installation.
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.
