PDC Parking Sensors
I managed to fix my PDC parking sensors on the X5. When I put the car into reverse I had a constant high pitch tone for a few seconds and the little green light on the PDC button used to flash on and off indicating a fault.

I put the car into reverse and asked my son to listen to each sensor in turn and tell me which one was not clicking. He identfied the culprit as one of the corner sensors as this was silent.

I ordered a replacement from ebay for 15 and installed the sensor. the PDC system now works absolutely fine with the front and rear sensors functioning perfectly.

Great tip...thanks for sharing. This will definitely go into my mental rolodex. :D

I have the same symptoms now , I have listened all the sensors at the back and they all make that clicking sound.
I tried listening the front sensors and I had 2 of them that dont quite click.
Is it true if the front sensors go bad then rear sensors stop working as well ?
I dont get how 2 sensors go bad at the same time.
Is it easy to replace the front sensors?

I blame the drive through car wash for faulting my PDC sensors. It is true. Once one goes bad, they all go bad. My PDC light doesn't even come on now.
