Hi Greydog Thanks for your reply It is the car brakes that come on when I reverse with the caravan or trailer ,they also come on when I try to reverse onto a small incline in a driveway thanks John

I have a towbar on my 2019 X3 got it fitted just after I got the car in February 2019. I had no problems with the rear sensors until recently and when I have my trailer or caravan on the back and go to reverse the brakes come on and you cannot override the sensors like before when I first got towbar fitted, also when you try to reverse onto a slight incline on the ground it does the same the brake automatically comes on You could reverse no problem before it is just recently this has happened . Any help appreciated Thanks John
