Interesting because yesterday after pulling out of a junction onto a fast A road the TFT dash on my L494 RRS died for about 3 minutes and then returned with all the right info on it. No alarms or warnings and as you say all the other things worked fine during the "black out" 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Connectors come loose on the dash.

I think there is a TSB.

Just unplug and replug

Thanks Andy I will try it

Tried unplugging and re-plugging still no joy still the same works for a while than dies than comes back alive again, I have bought a second hand replacement cluster unit, but it has got higher millage than mine about 30,000 + miles more, how can I correct the millage or will it auto calibrate?
