If you look under the spare wheel you will find the battery mounted in front of the battery you should see a white or grey plastic unit it has 3 plugs on top 1, White 1,Blue 1.Black that is the PDC controller One plug is for the front sensors one is for the rear sensors the third is for the Tow Bar electrics if they are fitted it turns of the sensors when the trailer electrics are plugged in There will be no warnings other that with a full scan if I scan my E53 it will tell you which part is not working EG. Rear sensor Centre Right or PDC controller error As I said these often get water damage Good Luck Dave
