I have no idea why but every time my reader shows wrong temp car have problem with start (i even compare temp in two cars at same time and every time when car start hard 318ti outside temperature was incorrect).

3 days ago i had situation when temperature does countdown (it was 29 outside) but OBD was showing 40 and goes down by 1 ... 39, 38, 37, 36, 35, 34, 33, 32 and stopped on 31 (whole counting took about 6 seconds and i saw all those numbers changing)

So what sensor do i need to change, to have accurate outside temperature reading on OBD?
