Sad to report a problem that I haven't seen on the forum.
In recent days when I've started my '21 Plus Four, the Stop sign comes up on the info screen. Engine has started all seems fine - except I can't select drive or reverse. So switch it off, count to 10 and try again. All is fine on the second attempt.
It's done this a few time now - so it looks like another trip back to the dealers.
Anyone else come up against this one? Maybe a dodgy earth or something?
