Description
Genuine used CAN bus gateway control module with primary OEM number 3C0907530A and secondary number 402063, listed for the Volkswagen Passat B6 (3C). The gateway is the central hub of the vehicle’s data network.
It links the separate CAN bus systems – engine, comfort, infotainment and diagnostics – and passes messages between them, and it is also the point the diagnostic tester talks to. When the gateway fails, typical signs are several control units that can no longer be reached on the diagnostic tester, warning lights that appear together for unrelated systems, a flat battery from modules that will not sleep, or the car not communicating at all.
This unit was removed from a vehicle and tested before listing. It is sold as a used original part.
A gateway is coded to the car, so a used unit normally has to be coded or adapted to your vehicle with diagnostic equipment before it works fully. Before ordering, compare the number on your existing module with 3C0907530A and the secondary number 402063. Matching the exact part number is the most reliable way to confirm compatibility.
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.
