I fitted one to my Tourer a year or two ago.
Not to bad a job.
If you have parking sensors they will detect a trailer which is a pain but they will not detect a bumper guard
You can get sockets with a micro switch in to disconnect the cars rear fog lights when a trailer is connected and I think that you can also monitor the trailers road lights and get a bulb out warning.
I have a facelift and have changed my instrument cluster. Apparently I need to fit a particular BMW towing relay and not a TEB7AS relay and then add a wire to the light switch module. I have not done this as I have not obtained the BMW relay but it is something I want to do.
My saloon did not need the bumper cutting for the tow bar.
what did you buy and what will you tow?
good luck and welcome to the forum
