[bmw9818]

my obc mpg figure is not moving off 17.8mpg

filled up about £20 been driving like a gay for the past 60 miles it just doesnt move it hasnt moved in the past 4 months ive driven the car it keeps going from 17.9 to 17.8 and thats it

ive got the coding plug from a 318ilux and mines a 316ilux, cause of that maybe?...

No you will need to press the set/reset button, as it is taking the average consumption over the miles covered not how much fuel you have in your tank.

Driving like a gay is pretty common for 4 pot drivers.

sounds like a challenge mate, give me 2-3 years going for an m3 conversion then we shall see,

and no way do i drive like a gay only recently when i was trying to improve my mpg figure, my 316 is decent dont no why everyone keeps taking the pis out of them, just have to shift properly at the right time and i can keep on the tail of pretty much majority of cars out there,

ok cool will give it a go, is that the button in the bottom rh corner?

yeesss i got it working one question will it average out? like it goes up and down when im driving then goes down when i stop, will it stay at a certain number after a while or will it keep fluctuating, thanks
