The fuel gauge gets stuck and doesn't move up unless i fill up the tank to the top. The tank has 60 liter capacity, when the low fuel warning light comes on and the gauge correctly indicates the low level, if I put in another 10-20 liters (which should then have 20 or 30 liters of gas in the tank), the gauge will not move at all. The warning light will remain on with the gauge stuck in the previous position.But if I fill it up to the neck the warning light will turn off, gauge will move up and show the correct amount. While consuming the fuel it has no problem moving down. The vehicle has 96,000 km and has been properly maintained.
