PDC parking error

[NFNICK]

Hi, my first post and would dearly like some advice please.

The other day, had the dreaded 'bong' sound and an error message on the screen saying the PDC system wasn't working along with the PDC button flashing green. After hitting OK the parking screen shows sensors, front and back greyed out.

So far I have...

Checked the fuse which is fine.

Cleaned the sensors.

Listened to all sensors. No sound coming from any of them.

Inspected the module in the boot. No water ingress, no corrosion on the contacts and no dirt or visible damage to the board, looks perfect.

The fact that no sensors are making any noise makes me think its the module but as I say it looks perfect. Are these easily checked?

Unlikely that all 8 sensors have failed simultaneously or indeed the front and back wiring looms.

Any experience of similar or advice would be very much appreciated. 

Thanks in advance

Morning Nick

Welcome to the Forum

Normally it will be one or two sensors that fail as you say, I would go back and test the sensors again. PDC on then ligtly touch each sensor with an ear close you should hear clicking and feel a light vibration. I would have a spare sensor to swap in the event you find a non responsive one (the trick is being able to get at the sensors) If a sensor is swapped and remains unresponsive check the loom from that sensor to the next for continuity.

Good Luck
