Rear pdc not working

[Midlifecrsis]

I've checked the fuse, box behind the carpet panel and checked that a couple were plugged in (maybe should have checked all 4?)

What can i try next fellas ?

maybe all four sensors have gone, would be odd to have all four at once though...

maybe the speaker/buzzer?

To find out which ones are off you can tell by listening or touching, the working ones will be vibrating slightly or making a slight buzzing sound

Superb. Now fixed. I checked everything as suggested and it seemed to be the speaker thing under the drivers footwell.
I took out the plastic panel and all connections appeared to be ok so i deceided to unplug both wires and re-connect it then hey presto it's now working perfectly - must have been a bad connection
