Well, I can manage everything myself, but would really want to get it fixed.
This is 2006 X3 and while I don't mind adjusting temperature myself, this car is mostly driven by my wife, and she doesn't take "no" for an answer
I drive 2003 X5 4.4 and don't have any problems with climate control there.
I think this could be an issue with the internal temperature sensor . I have no idea where it's located and couldn't find anything on google. Anyone with electrical schematic of the car could tell is there is an internal temperature sensor in this car?

Also , this car has only 20K miles on it , and rear breaks rotors seems to have very uneven surface . I'd like to replace these rotors and pads. Is this covered by warranty ?
