MPG figures on dash gauge totally wrong

I have Navdy running on my 2009 BMW 118D at the moment and the MPG figures displayed on the dash gauge are obviously wrong e.g. Navdy shows less than 18 and my car dash shows 48 or higher. My car is a Diesel and the average MPG is in the high 40s.

    Bumping this as I've noticed this too - I have a Honda Civic 2.2l diesel. What was the outcome of this?

    I have now sold the BMW and run Navdy on my new Mini Countryman Cooper S All4 (Petrol). The MPG figures still don't match up to the Mini computer figures and I haven't heard any changes have been made to address this. @ShineyAds what country are you in? I wonder if this could relate to calculations incorrect by region... a wild guess, it could also be the reported data over OBD
