After getting my golf back from the upholster today I have noticed that when driving the fuel gauge goes to empty and the trip computer has "--" distance left.
When i turn the ignition off and on again the fuel gauge shows what i think is left in the tank. But the trip computer sets itself to 3000km to empty.
They did have a sparky in to fix the vanity mirror lights after the headlining was replaced, could this have caused an earthing issue, any ideas please.
Thanks
