Description
Part number 045906019AB is a genuine <a href="/brand/volkswagen“>Volkswagen engine control unit for the 1.4 TDI small diesel, sourced from a running vehicle and verified through bench testing before listing.
This ECU controls the core diesel management functions of the 1.4 TDI — governing common-rail injection timing, pilot and main injection events, EGR valve positioning, glow-plug pre-heating, and turbocharger boost — keeping the small diesel’s fuel economy and emissions within VAG specification.
A failing ECU on the 1.4 TDI often presents as hard or extended cold-starting, loss of power at lower revs, excessive white or black smoke at start-up, recurring glow-plug or injection-related fault codes that persist after replacing the mechanical components, or sudden limp mode activation.
This is a used, tested OEM part to the original factory specification. Professional installation is recommended; VCDS or a compatible VAG diagnostic tool will be required for immobiliser adaptation and 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.
