Well Just came back from my holiday and took the GTI along and loved every moment of it
But during the last leg of my journey after I filled her up, the MPG, MPH etc valves went to 0

During the whole journey I was able to get 36ish MPG and now it displays 25

..... This might sound silly but I dont recall doing more that 60-65 on the motorway and wasn't stuck in any traffic for hours.......All my journey was motorway......
Also my distance travelled, average speed, average fuel consumption, and real time fuel consumption information have all gone to 0
Dunno whats wrong???, car sounds and drives ok.
Please any advice????
