Hi,

The PDC sensors on my e46 coupe don't seem to work. I get about a 5 second long beep when I first put the car in reverse after each startup, which I understand signifies a fault with the system.

I have tried that DIY test where I put the car in reverse with the ignition in position 2 and walked in front of each of the sensors to hear if they make a clicking sound, but none of them make any sound. Does this mean all of the sensors are faulty, or does it signify a problem elsewhere (e.g. a connection or cable somewhere)?

Has anyone had this issue before?
