Just as an observation, the F 0.1km indicates you're just into reserve whcih is why the warning light is on.
I'd check whether it's actually getting the right signal from the tank level sensor.
Personally, on my FZ6, I never bother with the fuel gauge, I just reset the Trip 1 counter to 0.0 when I fill the tank and know that in summer I get 200 miles full tank to reserve and in winter it's 175 full to reserve.
Once the display switches to F 0.0 I know I've got a theoretical maximum of approximately 40 miles before it's completely empty.
