Has anyone else experienced the intermittent failure of the data screen (fuel gauge, temperature, MPG., etc)? Mine remains blank for about 10% of the time on start up, quite randomly, then reappears after a run. Is this a software issue? One JLR dealer thinks it may be the result of water leakage through the windscreen seals; another that it is a wiring problem. Any thoughts would be gratefully received. (2016 HSE.) .
