Parking Sensor Failure

Go to dealer! Yeah, right...

I remember reading here about setting them off by getting someone to walk around the car and feel the pulse on the sensor to identify which one has failed. I think it's a rear one, but both from and rear are emitting weird long tones erratically rather than bleeps.

Anyone remember the sensor part equivalent, I seem to remember it was Volvo? Could it be the ECU?

Mine stop working when there is the slightest moisture in the air.

They were fine all summer, but have now hibernated - putting it down to moisture in the boot.
They stopped working after the first frosty night this year, but last year was frostier (Dublin, wind chill from sea) and not effected then.

Ah, well...

And they've stopped working again. Also not got much petrol in the tank, getting the 'Limited Cruising Range' huge petrol-pump icon with a quarter of a tank left.

Perhaps she just need a drink?
