Reverse alarm funny

[Meadway]

My Roomster 3 has the mimic diagram appear on the radio display when reverse is selected. On a few occasions recently, when I engage reverse there is the usual short bleep, the diagram appears, and almost immediately there is a loud beep from somewhere the nearside B pillar and the diagram disappears. The sensors all appear to be OK. Anyone else experienced this, please?

Does it occur when it is raining or has rained ?

Mostly when it's dry; but it hasn't happened for a week so fingers crossed . . .

Strangely,mine did this exact same thing backing out of my drive today, never done it before, the loud beep certainly woke me up! The display also disappeared at the same time.

Later when I backed in on my return they worked perfectly, it has been dry here recently, so I'm baffled, will have to wait and see if it was a one-off.

I suppose mine is averaging about once a week. I'll have a dig in the boot today to see how many connectors I can find; bad connections are, after all, the cause of the vast majority of electronic faults.
