Product details

This 13 pin electric wiring kit from TowTec is made specifically for your AUDI A4 B7 Avant . The operation of this 13-pin electrical kit is very simple: It is detected by the data bus system in your AUDI A4 B7 Avant and is ready for operation after the vehicle has been coded for trailer operation. From now on, the electrical kit will inform you via the car's own system if the trailer lights are faulty.

A shutdown of the factory-installed parking assist function of your AUDI A4 B7 Avant is supported by this 13 pin CAN-bus module electrical kit. High-quality, vehicle-specific plug connectors, colour coding, custom cable lengths and a detailed A4 B7 Avant A4 B7 Avant installation manual are all part of this wiring kit. No drilling in the rear panel of the vehicle. A grommet is already present on your AUDI A4 B7 Avant. It is used by this vehicle-specific 13 pin wiring kit. It's not required to connect the cables to a trailer socket. A socket is already connected with this kit.
