Do you have the "Trip computer" set to reset each journey?, the box ticked in Idrive.
Also do you reset the MPG after filling/each long journey?.
I did a 45 mile each way trip yesterday, Duel and A roads town traffic and some stop start traffic, car returned 43.5MPG overall, now covered 745 miles.
Sport mode "Chassis only" till town then ECO through towns.
