Description
This listing covers OEM part 03G906018CD — a genuine used, tested Engine ECU Control Module for the Volkswagen Passat B6 (2005–2010), one of the most widely sold executive saloons in Europe. The 03G part number prefix identifies this as a diesel engine management unit from the VAG 1.9 or 2.0 TDI engine family.
The TDI ECU co-ordinating common rail or pump-injector diesel injection on the Passat B6 manages injector timing, fuel rail pressure, exhaust gas recirculation rates, and turbocharger boost pressure control. It processes inputs from the rail pressure sensor, camshaft position sensor, and mass airflow meter to optimise diesel combustion efficiency and emissions compliance.
A failing TDI ECU on the Passat B6 may produce symptoms including excessive black smoke, loss of turbo boost, limp mode engagement under load, DPF regeneration failure, or stored fault codes for injection quantity deviation and rail pressure plausibility. Starting difficulties in cold weather are also associated with ECU-related fuel delivery errors on this platform.
Sourced from a written-off Passat B6 and tested against the 03G906018CD OEM specification, this unit provides a cost-effective path to restoring correct engine management function. Professional fitting is essential, and the ECU will require coding to the target vehicle using VCDS or equivalent VAG-compatible diagnostic software. Returns accepted within 14 days.
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.
