I know exactly what's causing it, I have the same problem with my Mercedes, it's got a bad sending unit in the fuel tank, my fuel gauge jumps from 1/2 to 1/4 all the time then my low fuel light comes on, when I have a 1/4 of a tank, but my low fuel light is pretty accurate, when it comes on I stop and get fuel it doesn't matter what the Gage says.
