Fitment guarantee and VIN verification

Each USB hub undergoes data transmission verification with the MMI system, smartphone connection stability testing, and charging current parameter checks before being prepared for shipping.

Fitment / installation tip: The initial designation 4N0 (electronics and multimedia group 035) defines a modern, fast data interface module used in the flagship Audi A8 D5 and adapted for A6/A7 models on the MLBevo platform. USB ports in the storage compartment are exceptionally prone to mechanical damage of the internal metal contacts from pulling on the cable, dirt accumulation, or spills. Port damage manifests as constant Apple CarPlay / Android Auto disconnections, a “Device is not supported” message on the MMI screen, or a complete lack of response when connecting the phone. Replacing it with a functional OEM module restores full functionality of the factory smartphone interface. Before purchasing, we recommend comparing the OE number stamped on the rating sticker or verifying it using the vehicle’s VIN.
