Hi Jose,
this spaghetticoder is pretty confusing, the 528i doesn't have an additional charcoal filter valve, but it has a fuel tank breather valve and the evaporative emission system is combined with this breather valve. This is also called purge valve. (The Evaporative Emissions System (EVAP) allows fumes from the gas tank to enter the engine to be burned, rather than vented into the atmosphere as an emission.)
Here you can find a picture of it:

and you can read there that this causes the evaporative 44 error code.
I searched for the intake air temp sensor, it is under the throttle body, see drawing attached.
RT is rot == red
here are the color codes:

Enjoy!
