The control box is a BMW part, and I’ve no bulb error messages. One thing, it is supposed to disable the parking sensors when the tow bar is being used. It doesn’t do that, get a consistent ‘beep’ from them when cycle carrier is attached. Now I fitted the parking sensors years ago with the genuine Rover kit, but it never shows up on any T4 sessions. Do you think that’s why the tow bar electrics module doesn’t disable the sensors as the car doesn’t register them being fitted? On a slightly different note, I seem to remember reading somewhere if the sensors are fitted and you have a tow bar the car recognises this and adjusts the signal from the sensors to compensate for the extra length from the tow bar?

do you know what the BMW part number is? There is a way using a BMW relay to monitor trailer lights, you need an extra wire from oh goodness I cant recall to the LSM.
The parking sensors are more accurate with a tow bar fitted, by this I mean you don't need the parking sensors going off when you are so far away from anything. With the tow bar fitted you are that much closer and so they beep at a more appropriate time. Have you checked the trailer board lights for all working ok?
