Isn't the fuel range calculated from your average fuel consumption?

Until you drive somewhere it won't have an average to base its calculation on.

Sit with the car at idle and preferably at night so its nice and dark.  Put headlamps on and watch the display. Does it flicker slightly?

If so, your alternator may not be charging correctly.

You can ignore everything I've just written and check the battery voltage at rest and under load, but I like to be difficult.  :P

Are you sure you have put the original MID back in?, F and 0 come up if the MID has been swapped for a manual to auto, or visa versa.

Hi have found the problem but it has damaged the mid, the board on the back of the rev counter had gone were the fuel gauge gose throgh it sending volts to high have changed it and the old mid works on range but the new one dose not just say 441 then F, also have found out what the brown and white wire is for its for tec2 signal and one black wire is the other, tryed to find what part has gone on the display but cannot see it, so going to leave it for now until the screen gose and have to get another, at least its stopped flashing that there is hight volt.
