Description
Part number 030906027T is an OEM engine control module for the <a href="https://giantparts.eu/brand/volkswagen“>Volkswagen Polo and Golf A2/A3 generation small-displacement petrol engines — compact VAG models celebrated for their efficiency and straightforward engineering. Removed from a running vehicle and tested, this genuine used unit delivers OEM-standard engine management performance.
The ECM controls the fuel injection and ignition management system for these small petrol engines — governing injection timing and pulse width, ignition advance, idle speed control, cold-start enrichment, and lambda sensor feedback for fuel-efficient, low-emission operation within VAG’s Digifant or Mono-Jetronic calibration.
Symptoms of a defective ECU on Polo and Golf A2/A3 small petrol models include failure to start, rough or hunting idle, hesitation under load, poor fuel economy, engine stalling, and fault codes covering injection signal faults or lambda circuit anomalies.
Supplied as an OEM-matched, tested used unit for Volkswagen Polo and Golf A2/A3 small petrol applications. Professional installation is recommended; VAG coding and immobiliser adaptation may be required.
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.
