Very recently, my 2001 X5 has developed a PDC problem - whenever I start the car up, and either put it in the reverse or just press the PDC button, the button will flash and the system will not work for about 30 seconds - it will either beep constantly, not make any noise at all or beep on and off as if there is a nearby object but at a constant rate and when there are no objects nearby - all the while the PDC light is flashing.
After that initial 30 seconds, the system is fine - light is on constant, sensors do their job at any time that the system is activated within that journey.
As soon as I turn off the engine for anything longer than 3 minutes, when I restart it the first 30 seconds I have the same problems again
I have checked all 8 sensors while the system light is flashing and they all click to show they work. Quite confused as to what this is - it seems to be related either to temperature (hence something 'warming up' in the first 30 seconds) or something that the cars electronics do in the first 30 or seconds after startup that it does not do again.
It has done this on almost every start for the last couple of days, but not every single start.
Any ideas?
Thx in advance
