Took the 90 for a drive with the scan gauge connected and it is showing between 4 and 14mpg which is clearly incorrect anyone on here with one know how to re-calibrate it
thanks in advance Rob DEFENDER 90 TDCI XS, I hope everyone is well and your land rovers make you happy |

hi,
I am also using the scangauge and also do not think that fuel consumption is correct ! but no idea what to do ! As late as possible, I will use it for code of defect Philippe current : defender 110 sw 2.2 puma 2012 and 230.000km today and again my Range Rover VM2.5 engine from 1992 and 528.000km today.

Hi,
I've just fitted one this morning so will be going through the fuel calibration process next time I fill the tank up. How did you calibrate it initially - did you go through the process in the instructions when you filled the tank? Cheers  |

Did you set the engine size and diesel type according to the manual (Basic Setup Parameters, page 11)?
MPG accuracy is not perfect but nowhere as a far as 14MPG, at least in my case, and it improves with subsequent fill-ups if you take the time to adjust the volumes of fuel to help calibrate the scangauge (Calibrating the ScanGauge, page 20) |

Mine is spot on every time.
I never used a calibration procedure, just put the parameters right first time it is powered up(engine size, tank size and diesel type) and at each fillup log the liters put in. Since then it is working a perfect. The only nasty thing is that when idling the consumption goes up and you need to drive a bit to get it down. The further you are in a tank/ the more fillups you have logged, the quicker it gets back to normal values after idling and the less variation you will notice / the more precise short trips become.  |

Hi
I've reseted my scangauge but can't seem to reset the litres on fillup... I've had a problem during the summer, on the fuel breather pipe and was unable to fillup the tank for a few months till get it sorted... Now on fillup the other day the scangauge states I've filled uo 450L!  wich might be true because I never set them to the right amount in the meantime...
Now, the only way to tell the scangauge the right amount of fuell in the tank is to let my finger on the < key till it reaches 65 wich I recon it would take me about half an hour? Can't I reset this item?
