Kia Sorento Diesel auto XE. 2006 - Reversing sensors - Craigh

The sensors beep at a constant rate and do not change when nearing an object.

Cleaned the sensors but to no avail. Any ideas?

You should be able to disconnect them one by one till you find the faulty one.

Been underneath the rear bumper, no joints/plugs here to disconnect. Traced the 4 wires up into the boot and into the rear quarter panel. Thats as far as I got!

Does anyone know if this is where the electronic unit is? If so then how does the interior panel come off without damage?

Please advise as it's a bit wierd trying to ignore the beeping noise while reversing!

Thanks for your help.
