It's the sign of a fault in the system......... Unfortunatelly u have to go on guessing / random replaceing repair mode coz :
Diagnostics
The PDC ECU has no diagnostic connection to enable faults to be retrieved using TestBook/T4. An on-board diagnostic routine monitors the system and alerts the driver to a system fault by emitting a tone from the sounder.
If a PDC system fault has occurred, the sounder will emit a continuous tone for 3 seconds and the PDC switch LED will flash continuously when reverse gear is selected.

First of all check all connectors from the sensors.....behind the rear bumper. Its a sensor/bad contact/wiring issue cos the fact that the system entered in the fault warning mode proves that the ECU is working

Arh that's spooky mine has just started to do exactly the same thing today. Was going to put it on ere, and it was the first thread I came across.
