Have a 54-plate Cooper and like a lot of people, started getting the 10-second beep noise when engaging reverse from the PDC Sensors after all these years, given them a good clean and replaced the fuse but still not working. Can only assume that theres a wire/connector issue or the control box is buggered.
Either way, I'm going to try and remove the rear bumper and check all the connections and I was wondering if anyone knows of a guide or has a Service Manual for the PDC/Control Box installation, any help would be much appreciated.
Normally the long bleep means a sensor has gone - stick it in reverse (just ignition no engine) & stick your ear to each sensor - are they all clicking?
