Descrizione
This is a genuine Volkswagen CAN Bus Gateway Control Module for the VW Passat B6, supplied under primary OEM number 3C0907530C and secondary reference 402063. It is the network communication module that links the vehicle’s electronic control units and supports stable data exchange between major onboard systems.
Acting as the central communication hub, the gateway manages signal traffic across the CAN data bus so modules such as the engine, transmission, ABS, comfort and diagnostic systems can communicate correctly. A healthy gateway is essential for reliable fault scanning, system coordination and proper interaction between multiple electronic functions.
Common signs of a faulty unit include communication errors with several control units, intermittent warning lights, battery drain concerns, loss of diagnostic access, or electronic systems that stop responding as they should. In some cases, unrelated faults can appear together when the gateway is no longer handling network traffic consistently.
This is a used original part, removed from a vehicle and tested before sale. Match 3C0907530C and 402063 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on the vehicle 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.
