Have a 2012 estate and today reversing sensor gave long continuous beep. Next time on the screen its jumping all over the place mainly middle to right hand side. I assume one or more sensors have failed or perhaps wiring. Whats the easiest way of removing and checking them plus is there a way of finding out which one or more thats causing the problem. They are the type that sit flush in bumper and are colour coded to match. Had a quick look but it doesnt seem that easy to get to them without removing bumper. I dont have vcds etc but is there a way of disabling them until I get it sorted or perhaps do without.

As no one else has replied...

Firstly, give the sensors a good clean. Dirt on the sensor can send them haywire.

VCDS can identify sensor faults - maybe Christmas can justify the purchase.

VCDS can also "uninstall" the rear parking sensors module from the installation list.

The module itself (on my hatchback) is in the boot mounted on the LHS behind the side covering. I expect the estate/combi is the same as the floor pan is identical on both models. Without VCDS I would unplug the module from the loom.
