19 plate Berlingo reversing issue

[middgm]

Hi all 

Just noticed that when I reverse the screen doesn't show obstacles on it. The settings are set to on so it should work as normal. 
Does it mean the sensors are broken ?
Reverse lights are working OK but nothing appears on the screen 
Any ideas please

Are the sensors clean? The roads are filthy at this time of year, and the manual recommends keeping the sensors clean (though my van's sensors are working even though they're covered in a layer of grime).

Would it stop the screen on the dashboard showing the reverse animation starting?

Just cleaned them, nothing on the screen. By the way the screen is working perfectly in every other respect

Not sure but I'd think unlikely. But if they are dirty, there's no harm in wiping them with a damp cloth and seeing if anything changes.

Has it just started doing it?  Might be just a temporary blip. These screens can be a bit temperamental - mine occasionally reverts to showing everything in French.

Yes it has , strange really because the screen has been OK since I got it. Its as though the signal isn't telling the screen to show the function.

I'm assuming the action of putting it in reverse starts the process, if that's the case I wonder if there's a fuse gone.

Yeah, mine starts once I put it into reverse - the screen changes and there's a beep.

This web page - https://asacannes.com/en/probleme-de-rad...-berlingo/ - lists some possible causes of the reversing warning not working. A process of elimination suggests it could be a fuse. It also suggests a test of the sensors involving bringing a coin close to each sensor and listening for a 'sizzle'.

Have you hit the switch on the dash to disable the rear park assist by accident? On my B9 it was down on the right next to the steering wheel but just out of sight. Not sure where it would be on the K9.
