Help! 645CI Parking Sensors Stopped Working.
Discussion
Can anyone give me any ideas why my parking sensors are failing. All of a sudden they have stopped working. The second I put the ignition on, PDC fail symbol is displayed on the dash. I have checked the relevant fuse in the boot and it's fine. Any other ideas for a solution would be most wecome as at the moment I'm all shook up.

Hi just did this on my e60. To diagnose which sensor is faulty, switch your PDC on and place your ears close to each sensor on the bumper. You will hear a faint clicking sound on the ones that work. The faulty one wont make a sound. remove and replace with a replacement item. Bought mine off ebay for 15 quid. It was a rear bumper off job on mine. not sure about the 645 though.
