Got a problem with parking sensors on autobiography sport 59 plate

The reader said that it couldn’t see the parking module so I got another.

now it is saying that the front and back parking sensors not working. But it says the same thing when I put both parking modules in. So is there something else I can do looked at the wires to the sensors that all looks ok.

Is there any way to check the sensors work. Can not hear any clicking on them . Not sure what to do now

 

I had an issue with my defender where the parking sensors wouldn’t work / a redbox around the car on the parking dash screen. It turned out that the tires were over inflated and for reasons I haven’t quite worked out the tire pressures are tied into the pdc system. Might be worth a check.
