Question about 2007 BMW X5 3.0si SAV
I just picked up my new Baxley trailer and all the way home, the X5 gave me warning left and right trailer brake lights. The trailer lights are working fine. BMW here said they never heard of such a problem. Any ideas on where to start. Trailer uses a 4 pin - which I have. All my install, hitch and everything was done by BMW.
Thanks for any help
There is an electrical switch box that is supposed to be replaced when installing the tow hitch. Sounds like they may have skipped this

Ask your dealer to recode the trailer unit with the trailer connect to the car and in this way the car will see that the trailer is on and will accept it bmw is a funny car.
