The light is telling your you have about 30 miles remaining, which seems like a standard since VWs and Dodges I've owned use the same miles remaining mark.

Note: I don't know if the indicator is adaptive--that is, does is come on earlier if you've been hammering the gas and dropped MPG down. Something I'll look at next time I'm at the track--I average 5 MPG there!
Ok I was just curious because on my other two BMWs the needle is almost on the empty mark when it lights up. On my E 53 the tank is over 24 gallons. When I took that picture the light had actually been on for a little while. Wow 5 mpg. That would suck but for track time I'm sure it's worth it.
Totally worth it! As I get faster the mpg drops more
