Hi
When I put the car into reverse sometimes the sensors work as they should, the next time I just get a continual beep as if I am close to something, if I then turn off the ignition and back on again most times they are back working again. I have listened to all sensors and all are working, I do not get the fault beep when I turn on the ignition. It's driving me mad.
Any help would me much appreciated.
Thanks Tony

 

west470, I would say to cycle the car in and out of Reverse a few times to get the system to fail. At that point, check to see if all the sensors are beeping/squealing then. If they are, then you are looking at a cable issue between the sensors and the module in the tire well. If you need more assistance, let me know.
