    The PDC system on my car gas suddenly decided to stop working - any ideas as to where I should look first? The front sensors do work sometimes, but the rear ones have stopped altogether a week or so ago. All the sensors look OK, I haven't clouted any of them, so what could be wrong??

    If you get down and listen close to them you should hear them clicking.
    Ignition on don't start the car and if you have the button just above the ash tray press it if not select reverse.

    Agree with the above suggestion. Looks daft with your head seemingly glued to the bumper....but it works. Did this on my last car and managed to find the one duff sensor.
    Then the fun of changing it begins....

    Mysteriously, the PDC has decided to start working again!! I haven't done anything to it, but it did rain quite a bit a couple of days ago...….

    The PDC system seems to have a mind of its own, very annoying as it is useful to have it functioning on a biggish car like the X5, when parking in tight spots. Perhaps the sensors are particularly delicate, as I have had to replace sensors on all the previous BM's Ive had - not easy to do depending on where the sensor at fault is fitted!! At least they don't cost an arm and a leg - like some sensors do!

    Just got back from France after a 3 week holiday, and the PDC is playing up again......nether the front or rear works now. Am I right in saying that if any of the sensors is faulty - the whole system will not work? Also, while I know the sensors ought to click to show they are working, presumably the front sensors will only function when drive is selected, in the same way as selecting reverse to get the rear ones to work.

    Really annoying when gadgets like this play up, as you can tend to rely on their assistance more than you think you would!!

    The PDC seems to be working normally now, except that when I am in drive, you get an odd annoying bleep every so often, when I am nowhere near any obstacles, the only way to silence it is to press the PDC button on the dash, but then of course none of the PDC works! Any one got an answer for that?

    They should only work in reverse but you can press the button to turn them on going forward at a slow speed.

    How they seem to work on E60 ...

    Select reverse and they come on automatically (both rears and fronts). Automatically switch off above a certain forward speed (in drive). May be canceled by pushing PDC button. Automatically activated again by selecting reverse again. May be activated by pushing PDC button. Speed parameters for the last ie I don’t think that will work at 70 mph :D

    Mine have been known to get a bit of a hissy fit if large water droplets are sitting in front of the sensor.
