Angry Why does the 135i burn 39.5L/100KM petrol at idle, 0.0L/100KM while coasting?

Can someone please, do me a favour, and explain the science/logic behind the 135i burning

39.5L/100KM petrol @ a traffic light/idling
0.0L/100KM petrol @ rolling down a hill with foot off accelerator

much appreciated..
