Hi all

I am having a problem with PDC and looking for suggestions, if you have ideas please share.

When PDC comes on, it has a continuous beep from the rear.
PDC light is on solid (not flashing)
Feel test shows all 8 sensors are working (I hear all 8 ticking)
When an object is in the front of the car beep switches between rear and front
Carsoft diagnostics says no fault in PDC system

It seems that one of the rear sensors is overly sensitive.

What can I do?

Any opinions on the $20 sensors available on the net?
