Descriere
This CAN bus gateway control module is a genuine Volkswagen electronic unit for the VW Passat B6. It is identified by primary OEM number 3C0907530E and alternate reference 404339. Designed as the network gateway for the vehicle’s onboard systems, it is a key communication module within the car’s electrical architecture.
Its job is to coordinate communication between multiple control units across the vehicle’s CAN networks. The gateway routes data between systems such as drivetrain, comfort, diagnostics and infotainment, helping modules exchange information correctly and allowing diagnostic access to the vehicle.
Common signs of a faulty unit include communication faults between control modules, intermittent electrical issues, diagnostic scan errors, battery drain linked to network sleep problems, or accessories that stop responding as expected. In some cases, warning messages or multiple unrelated electronic faults may appear at the same time.
This is a used original part, removed from a vehicle and tested before sale. Please match 3C0907530E and 404339 with your existing unit before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle equipment and module configuration.
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.
