My fuel ligh has stared to come on and off at random; doesn't matter how full the tank is.The US version of the 899 has a 17L/4.5 gal. tank, and the fuel light comes on when there are 5L (1.3 gal.) left. I tend to fill up soon after the light comes on to avoid getting stuck on the road, but usually it only takes about 2.5 gal. (9.46L). I fill to the bottom of the filler neck, so I don't think underfilling is my issue, but the math doesn't seem to work out.
1.3 + 2.5 = 3.8 gal (< 4.5)
5 + 9.46 = 14.46L (< 17)
My fuel light seems to be turning on sooner than it should by 0.7gal./2.5L., decreasing my estimate of range by 20-30 miles.
How much does it take for you guys to fill the tank? I'm wondering if there is an issue with the fuel sensor.
