If your A4 has the Audi Parking System (APS), this electronics package will disable the rear sensors while you are towing and provide feedback to the driver when the trailer lights are not functional.

Installation is straight-forward and ties together seamlessly with the factory electronics systems. Connector provided is a round 7-pin, which can be adapted to other configurations with products available locally. Note: Please specific chassis (B6/B7) and model below when ordering.
