Ive read a bunch of threads about this issue, but I havent seen anywhere where it explains how the entire system works together so I could figure out what specifically is going wrong....

 

mine does it too.... but its just the computer error because im gettin the fuel i need at boost... all that matters to me lol

 

Me either. I've just learned to live with it and not trust the electronics. I reset the trip meter at every fill and fill up at around 400 miles, usually putting in about 15 gallons. I would love to know a cure for this, but it's just as easy to pretend that I don't have a low fuel light.

 

For the past few weeks I have driven 50+ miles with my DTE gauge showing ---- Then when I fill up I can usually put more in than normal and my gas needle goes a little past 3/4 full.... which is a lot better for me.... my light used to come on at like 250 miles... but now it comes on at like 310 or something... maybe driving way past the light helps reset it or something, or maybe the car knows how much gas you put in and thinks thats all that is in the tank... ?

All I know is Ive done this on my last 3 tanks and went from putting in 14.9 to 15.2 to 15.6 gallons each time... because the light goes off a little later each time now.....

either that or its all in my head... but a month ago I was filling up with like 12 gallons.

 

It seems that the system does not really know how much gas is left and sometimes sends you an 'educated guess'

All my gauges are in KM, which should be a little bit more sensitive (the smaller the measure unit, the most sensitive the readings should become) and the light usually goes on at 50KM to empty... but then it might show that I suddenly went to 30KM to empty and then back up (the light even goes out sometimes )

Anyway, as some other guys here I just learned to calculate consumption and I try not to pay attention to the fuel meter.
