PDC problem 09 E70

[monkeyT]

Wonder if anyone has had same problem...one my front PDC sensors is falsely indicating close proximity to something. Not the usual cause i.e. stuck debris. All the other PDCs are working fine and there's no fault showing. We've had some serious rain and flooding recently so could this be water ingress? Cheers!

Let me guess, rear left sensor?

I got a false reading the other day in the D. I got out and wiped it clean and the issue went away.

Pull it out and look at it bet it's cracked. I left mine alone for a couple of hot days to dry out, sealed it w/silicon and put it back. no more problems.

check for wire rub in the rear bumper as well. found mine on the rear passenger side had worn through the wires from them rubbing on the bumper. every time it rained bad , snowed or went through car wash , it went crazy. cut it and re-spliced the wires together. all good.
