PDC problem

[bernardlo]

I own a Phedra DVD Edition which has PDC built in. My problem is that I had problems with my left outermost sensor once a while, which notices obstacles which were not there, however this happens only when he had become wet, when he has become dry again, the system works ok, what hindered me from trying any repair. However now the pdc stops working, which means that none of the sensors detects an obstacle allthough the display and the one short beep should gives me an otherwise impression. I checked the connectors, disconnecting those I immediately get the warning in the display. I am now not sure, whether one defect sensors may stop the others from working without any alarm or whether the control unit is defect. Your input is very welcome!

Thanks in advance

I would guess, that the control unit is bad.
I don't think, that every sensor got dead at once...
First I would try a BSI reset (after stopping the motor, wait at least 5-10 mins, then disconnect the battery, wait 10mins again, and reconnect the battery. You will have to teach the window end-positions, and set the clock)
