Park Distance Control (PDC) fault

Hello everyone,

I have Mini Cooper R50 2003m, and just noticed that Park Distance Control is not working. When driving reverse, nothing happens, not even single "BEEP" when driving close to the obstacle. I checked fuse and it is OK, i checked two, one from the left and one from the right sensors (to check two in the middle i need to take bumper out), they are OK, checked the wires - alive, got voltage from them.

I got to the nearest service and they checked my mini with computer, said no alarms from PDC so far.

Anyone had this problem before? Where should check? Thanks.

There is a quick check you can do, if you turn on the ignition, without engine running, and then select reverse gear. if you go around and listen to each sensor on the bumper if its working you will hear it clicking, no click means a duff sensor, if all dont click then it means theres something wrong with the supply to them, maybe the control unit itself?

Shouldn't then PC diagnostic show that control unit is broken?

Ive looked through my manual and there doesnt seem to be a diagnostic code for the rear sensor system not working.
Maybe thats why the garage says nothings showing? was it MINI?

My park sensors have never worked since I purchased it a month ago. When I put it in reverse, the is no beeps heard. I have checked the PDC/PAS Fan Fuse and that is intact. There is no clicking from the sensors. I plugged in INPA and got the following:

24 voltage ultrasonic sensor general

Error frequency : 50

Short circuit to ground
Error present

Can someone point me in the right direction please. Thanks
