bmw x5 e53 actual intake air temperatur error?

[Derpsi]

Hello sorry for wierd title but i have carly and ive gone to live monitoring and the actual intake air temperatur reading is well quite off and i dont know where that sensor is and what part to order to replace it, look at photo to see what i mean.

i want to get this fixed so that i can finaly get some heating inside the car as its about -20 celsius at north of norway and with these freezer of a car its not pleasant to drive 250 km to visit another city :S
