Description
Part number 028906021DT is a genuine <a href="/brand/volkswagen“>Volkswagen Passat B5 engine control unit for the 1.9 TDI, sourced from a serviceable vehicle and tested before despatch — covering the B5 production range from 1996 to 2005.
This ECU controls all core functions of the 1.9 TDI diesel engine — managing injection quantity and timing, EGR valve operation, boost pressure regulation, and cold-start glow-plug control to maintain fuel economy and emissions compliance throughout the engine’s service life.
Signs that the Passat B5 ECU may have failed include hard or no-start conditions, stalling at idle, sudden loss of power, black exhaust smoke that cannot be resolved through mechanical checks, or persistent fault codes that re-appear immediately after clearing.
This is a used, tested OEM part matched to the original factory specification. Professional fitting is recommended and VCDS or a compatible VAG diagnostic tool will be required for immobiliser coding.
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.
