Interesting that almost all M140i and 540i drivers have average consumption of 11-13l, and all ya'll M340i's consume 6-7l 
I swear if your M340i consumes even just 8-9l overall AVG, you should've buy 320d instead...waste of car for your driving purpose.
Show pictures of "Factory consumption"-> those are only measures that are real, not your funny "reset just before 120km/h constant AB drive" lol
