Trying to sort a few niggles on my 04 4.8is, pdc used to work fine but all I get now is a long constant beep (no I'm not near anything) or and alternating beep if I cover either of the back corner sensors. Scanner 1.4.0 shows no faults. Anyone come across this before and got a fix please?

I had similar issue had to use inpa which told me which sensor was at fault.

Mine only does the long beep when the air is damp, and I've pinpointed it to front sensor.
