Title: MFD "average fuel consumption" values
Post by: simonkit on 25 January 2010, 17:08

 Another newbie question  :rolleyes:

 How does the average fuel consumption on the MFD get calculated, mines fluctuating all over the place - is it just based on the journey that you are current on ?

 thanks

 Simon

You sure you're not looking at current fuel consumption???
You should be able to get it for the journey and also for overall.

There's a little ¹ or a little ² in top-right corner of the display. You can flick between each using the round button on the bottom of the stalk marked '  OK || Reset  '

They can be re-set independently of each other - I use '2' as a lifetime total (Avg MPG 26.6) and '1' just keeps the trip totals you are on.

FYI, if you go somewhere the trip information re-sets itself after a couple of hours if you don't re-start the engine.

 Thanks for that - exactly what I'm looking for, mine is currently showing 1 which I guess is just based on my current trip, I'd rather have the lifetime option displayed

Happy to help! :afro:

^^^^^ to be fair the lifetime option is really only for information and it won't really change much.

Example: I did approx a 100-mile round trip last weekend through about 40miles of those bl00dy average speed camera thingys and managed 42mpg.... It improved my lifetime average by 0.1mpg!!   :shocked:  :laugh:

And also the "2" will reset itself after 9999 miles

Ohh, didn't know that! I've only covered 7800 since I bought mine.

Yeah, its a bit ambiguous in the manual, but I got mine with it on 7k or so and watched it reset itself as it ticked over a few months later!

I've sadly done 14k since I got mine in April.... but its been an enjoyable 14k :D

your number 2 value normally resets after 99 hours and 59 minutes of driving  :nerd:

I have always found the current mpg indicator to be useless. It is just much too eratic and needs some kind of smoothing to give it some stability.
