Hello,
A 2001 Audi A6 4B is equipped with a parking assist control unit with part number: 4D0 919 283, and the component is labeled "Parking System A6 RDW D07".
It should be able to detect AHK (AutoHotkey). Since I am not aware of any support for this function within the control unit, I have been advised to check the wiring diagram to verify whether the control unit 8Z0 919 283 is compatible with the parking assist system.
Does anyone have these control units running with functional trailer hitch detection?
Best regards, Rainer.
