Hello Fellows,
I've bought myself a used electric operated tow bar that I intend to fit to my 2012 3.0d X3 What needs to be done electrically do I need to have the ECU re-programmed to see the tow bar electrics? If so is this a BMW dealer only visit for the reprogramming? Or can other 3rd party companies carry out the work. PS I haven't seen the tow bar yet but it's a complete kit of parts including the wiring harness. Thanks JimX
