I will check the air sensor and also for error codes. Could this be also related to the fuel filter?

I will also try to do the leak check
Looks like there is a good chance you need a software update. We had another member in the N52 engine section reporting the same problem and had it fixed via a DME update:

Actually I did an ECU remap in January. I got the car enhanced from 265hp to 280hp. But before that change I already had this fuel consumption issue . I had tried Liqui Moly additives (different types), changing my way driving, changed the spark plugs to NGK iridium... I have a magnaflow catback and a K&amp;N filter (not an intake, just the filter).... Oh well...

I really appreciate your guidance bro and everybody else too. (y)
