On the centre dash my fuel miles left has suddenly gone to 9990miles left and doesn't change. My fuel bar gauge on the right seems to still keep track of the fuel but of course the number is wrong. Anybody come across this before? Cheers.

Have you tried reseting the computer?
If the 9990 represents Range just put that in the display, press and hold the OK button on the steering wheel until it resets and see if that clears it.

Try a reset, then it needs to be driven, unless you have recently rest it, it’s only as food as the info it collects for the fuel going in calculated by the fuel used, the miles driven and the way it’s been driven.

My 65 plate sig nav does it all the time had a word with the dealer and they said nothing could be done.
