Description
This Audi CAN Bus gateway module fits Audi A8, S8 and D3 models and carries primary OEM number 4E0907468C with secondary reference 8003. It is an original communication control unit used to manage data exchange between key vehicle electronics and onboard systems.
Working as a central network interface, the gateway routes signals between different control modules so systems can share information correctly. It supports stable communication across the vehicle’s electronic architecture, helping diagnostics, convenience features and other control units interact as intended.
Common signs of a faulty unit include communication faults between modules, intermittent electrical issues, warning messages, battery drain, loss of diagnostic access or multiple systems showing unrelated errors at the same time. Network problems like these often point to a failing gateway or internal communication fault.
This is a used original part removed from a vehicle and tested before sale. Match 4E0907468C and 8003 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required after fitting depending on vehicle equipment and system 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.
