Description
Part number 038906019HJ is a genuine volkswagen“>Volkswagen Golf 4 engine control unit for the 1.9 TDI diesel, removed from a running vehicle and individually bench-tested before listing — sitting within the trusted 038 ECU family that served Golf 4 diesel variants from 1997 to 2004.
This module controls injection timing, fuel delivery volume, turbocharger boost, EGR valve position, glow-plug pre-heat, and cold-start enrichment on the 1.9 TDI, providing the precise diesel management needed for the Golf 4’s performance, fuel economy, and emissions compliance under VAG calibration.
On the Golf 4 1.9 TDI, ECU faults are a known cause of limp mode that clears only when the engine is cold, intermittent no-start after hot soak, rough running with no identifiable injector or sensor fault, or smoke from a single cylinder bank combined with misfire codes that don’t respond to injector replacement.
This is a used, tested OEM part matched to the original factory specification. A qualified technician should carry out the installation; VCDS or equivalent VAG software will be required for immobiliser 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.
