Does anyone know if my 2017 Q7 is pre-wired for a brake controller.I installed a factory hitch and module, I bought from
the dealer. My car did not come with factory hitch. At first I thought the module has a controller built into it but I'm not sure. I towed a small camper with it this
past week-end but couldn't really feel the brakes on the camper.( didn't go very far ). Any thoughts ?

Don't know if his helps, but when they installed a hitch and wiring kit and controller on my 2009 A6 Avant, the shop also needed to code the car's computer that it was now trailer equipped. It now recognies a trailer when it is connected, and resets the transmission shift points. Mine is using a 4 prong so I can't say about the brakes. I suspect yours needs to coded too.
