Fuel distance till empty
Just filled my 1998 S8 fuel tank to the brim and the computer is saying 255 miles left till I run out, this can't be right surely?
90 litres = 255 miles = 13mpg!. Is there a way to calibrate this or is something not right? I own a 1998 Jaguar XJR and a 2001 M3 also and they're nowhere as bad as this. |

Hi and welcome to the forum.
If it's like the D3 then you have to drive a bit so the computer can calculate the range based on your current consumption. If you're sat in city traffic then 13mpg sounds about correct.

The PF D2 was the same, it's based on the last little while of driving, so if you hit a nice long stretch of road, it'll start to climb up.

It calculates that figure depending on your recent driving history: so that suggests that you've just been either:
1 - doing a lot of urban stop/start driving and/or 2 - hoofing it a bit (only you know which…). It should recalibrate if you then start to drive it on longer runs (e.g. motorways): my wife would typically find that she could drive it for more than a hundred miles before the "remaining range" figure started to fall…. Not the most sophisticated system, but ok once you get used to its logic. Last edited by tintin; 24th October 2014 at 06:26 PM. |

Like said before it depends on recent driving. I have got it showing 150 when flooring it and 500 doing steady 50mph on speed limited motorway roadworks. Under normal circumstances it is showing 300-320 miles on full tank for me.

Cheers everyone, I have only had the car a week and in that time the airbag light came on and it's run out of fuel with a quarter of a tank showing.

Running out of fuel is common, how much fuel did you put in to fill up from there. i am guessing the problem is the usual issue with the fuel pump. Sometimes when its replaced, its not seated correctly as its a ballache to do and the result is that the lift pump cannot get fuel from the second half of the tank once the level drops.

I put in 75 litres to fill it up, I take it since it has a 90L tank 15L is sitting in one of the sides unused?

I recognise that S8 - did it come from Swindon by any chance?
