    I have a very similar problem on my 320d SE. When I engage reverse, I either get a constant beep that stays for as long as reverse gear is engaged. Other times, the beep will last for three or four seconds then the sensors will work correctly. And to confuse matters more, sometimes it will work exactly as expected. By that, I mean when I engage reverse all is silent until I actually reverse near to something.

    Any ideas???
    Regards

    Get the codes read at a good BMW indy or main dealer, could be a poor connection I suppose

    I've actually got a diagnostic box and Carsoft software on my laptop, but at the moment am struggling to get it working correctly. Everytime I try a test, it fails half way through and shuts the program down. Will sort it soon hopefully and will indeed check the codes.
    Regards

    Read the codes and all is good with the PDC system. The computer did not throw up any codes so I'm at a bit of a loss.

    The fault changes every time I select reverse. Sometimes it works perfectly, normally after a descent drive. Other times I just get a 5 or 6 second tone then it begins to work. Other times I get quick beeps as if I am nearing an object even if I am completely clear.
    Regards

    Yes mate I had a read right through the thread. Maybe missing something, but not too sure about the relevance to the PDC problems I am having.

    I have got the Carsoft working great now, thank you. I have reset all the codes and been driving it today and will check the codes again tomorrow to see if anything has come back.

    Quick question! How is it possible to have so many faults listed but not have a light up on the dash?
    Regards

    Ray

    Unless it's a code that will really effect the car then the light won't always come up.

    You should be able to view the PDC sensors live data and see what is working and how well I would think

    Been having a look for the last few nights, but there is no option on the carsoft programme that allows you to view live data of the sensors etc. I'm struggling to figure out why it is so intermitant. Would I expect to see a failure code if there is something wrong?
    Regards

    Unfortunately not, if the sensor "thinks" there's a obstacle there then there's nothing to tell the sensor there's actually not, hence no code will be generated if the distance measuring goes up the shoot
