Description
Part number 3B1907401B is a genuine <a href="/brand/volkswagen“>Volkswagen Passat B5 executive engine control module, removed from a running vehicle in the B5 production run spanning 1996 to 2005 and tested before listing.
This ECU manages the full engine control strategy for the Passat B5, overseeing fuel injection timing and quantity, ignition mapping, EGR operation, boost pressure on turbocharged variants, and integration with the Passat’s CAN bus network for cruise control, instrument cluster data, and immobiliser communication.
ECU faults on the Passat B5 typically manifest as unresolvable limp mode, stalling on warm restart, sudden loss of power, fault codes pointing to data bus communication failure, or an engine that cranks normally but won’t start despite healthy fuel pressure and ignition components.
This is a used, tested OEM unit matched to the original factory specification. Installation by a qualified technician is recommended, and VCDS or compatible VAG diagnostic 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.
