I took delivery of my Discovery Sport HSE 3 weeks ago. When the fuel gauge chimes a warning lamp -- my estimate of remaining fuel is about 3.5 to 4 gallons if I am to assume the tank is 18.5 gallons. I use a 3rd party application to track gas mileage based on a simple total mileage vs. amount of fuel (gallons) required to re-fill the tank to the top.
I asked the Land Rover Dealer what is the true setting (default) when the fuel warning lamps trigger on. I could not get a straight answer. I asked him whether he was aware of a service bulletin re: fuel gauge calibration. He insisted my DISCO Sport was up to date with all firmware / software updates.
This is frustrating because I am not sure what to believe in terms of the RANGE mileage calculation vs. what I know what is in the tank and the average MPG. After reading the string of prior post -- I suspect the reserve lamp should be set around 1 to 2 gallons remaining of fuel? I don't mind the higher value (as previously mentioned) -- but the RANGE (e.g. 285) when I know under normal driving condition I should be able to max (to zero) at least 325 - 350 miles.
