Is there a leak in one of the fuel lines? Check the length of the fuel lines from the pump (you may need an extendable mirror to see the top of gas tank) right up to the point where it enters the fuel rail on the engine. Take special note of the junctions and try to do it with the car running and at a slight idle so fuel is pumping. Check next for a smell of too much gasoline along the fuel rail as one of the injectors may be improperly seated and or broken and leaking. Has the service engine check engine light come on at all or come on and gone out. If your o2 sensor(s) go you use more fuel. If they go there should be a code stored in your PCM (computer). You can pull any codes out of that car by finding the connector and jumping it. Also if your air element(filter) or any pipes are clogged in that system up to the throttle body you will use much more fuel.
Let me know how these tests go

If is for a 3 series compact (318ti most common) then
P2799 is the intake air tem sensor 2
Which would explain the high idleing. Probably a sensor problem (bmw will charge) a competant mechanic should do it easily.
