Fuel consumption problem

Hello.

Ive got problem with fuel consumption in 2018 640ix gt. Over some time it grown up.
While watching fuel economy indicator consumption is maximum while coasting or braking with drive or neutral gear at speed between 0-25 km/h. Doing the same with speed higher than 25 consumption isnt maximum. Also if I press thortlle slightly, about 5-10%, consumption at same speed range is also maximum. At higher speed consumption decrases. Other thing is that if I press thortlle to maximum at any speed consumption is maximum but if I release thortlle there is some lag at indicator and it shows maximum for 2 seconds more. I think it is not normal behaviour. Currently there is no error.

Recently Ive replaced Valvetronic because old one was broken. New one has been adapted.
