    I have got my front ones working, the cable behind the drivers side had rubbed on the bumper. The back four however still won't work. I'm getting the 4 red lights, all four of the back sensors a clicking when in reverse gear so I assume they're working. Does anyone have any ideas or suggestions of what to try next.

    When you say the front ones are working now, does that include the beeps? If yes, ignore this...I could be wrong but I think there is a setting in the screen menus for turning the accompanying beeps off.

    The font loom had rubbed on the bumper, breaking 5 wires, I soldered bridging wires across to repair, the front now work as they should. However the back just have the solid tone when reverse is engaged then the 4 red lights come on the rear indicator bar, the front continue to work while the rear have disabled themselves.

    Do you have a towbar fitted? Mine sometimes goes mental if the towbar cover is on wonky.

    Nope, no tow bar. I've tested the continuity of the sensor loom and all is fine.
