Description
Part number 3B0907557D is an OEM engine control module for the <a href="https://giantparts.eu/brand/volkswagen“>Volkswagen Passat B5 platform — the executive diesel and petrol family car produced from 1996 to 2005. Sourced from a running vehicle and thoroughly tested, this genuine used unit provides OEM-standard engine management performance at a competitive price.
The 3B-prefix ECM oversees engine management on the Passat B5 powertrain — co-ordinating fuel injection mapping, ignition timing, idle speed control, sensor diagnostics, and CAN-bus communication with the vehicle’s immobiliser and ancillary control modules.
A defective ECU on the Passat B5 platform can produce symptoms including no-start conditions, intermittent stalling, erratic idle, power loss, and stored fault codes covering engine sensor signals, injection control, or CAN-bus communication faults across the vehicle’s network.
This is a tested, OEM-matched used unit for the Volkswagen Passat B5. Professional installation is recommended; VAG-COM or VCDS coding and immobiliser adaptation are typically required after fitting.
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.
