Hi folks. My PDC is doing that long 'booooooop' tone indicating an error. If I were to unplug the sensors one at a time, would they help me find a faulty one or would the act of doing that just compound any issue? Ta.

Personally I wouldn't have thought so, but im not auto electrician

have you tried cleaning the sensor with a cloth... ive had to do that in the past, and also had one that was slightly pushed in so had to get underneath and reseat it

Thanks. I had a look with a torch last night, but I couldn't see anything suspicious. I'll take a better look over the weekend and probably give them a wipe anyway.
The only thing I've done lately is check all the engine compartment fuses regarding a different issue. The PDC problem occurred the next day... But the fuse for it is in the boot!
