Description
Part number 3B0907557C is an OEM engine control module for the <a href="https://giantparts.eu/brand/volkswagen“>Volkswagen Passat B5 platform, covering the executive diesel and petrol saloon and estate produced from 1996 to 2005. Removed from a running vehicle and tested, this genuine used unit represents a proven OEM replacement for a faulty or failed Passat ECU.
The ECM co-ordinates key powertrain functions on the Passat B5 — controlling fuel injection mapping, ignition timing, idle speed regulation, sensor monitoring, and integration with the vehicle’s CAN-bus network and immobiliser system for reliable, consistent engine operation.
ECU faults on the Passat B5 may present as hard or no-start conditions, intermittent engine stalling, rough idle, sudden power reduction, and diagnostic codes covering injection control, sensor signal faults, or CAN-bus communication errors.
Supplied as a tested, OEM-matched used unit for the Volkswagen Passat B5. Professional fitting by a trained technician is advised; VCDS or VAG-COM coding and immobiliser matching are typically required.
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.
