3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
Just bought a 2000 323ci two months ago and I need advice? The outside tempurature gague is stuck at -40 degrees. Sometimes while i'm driving, the computer will beep and then the -40 will be flashing on the computer. Any idea why? Also, the storage compartment over the ashtray is open and will not click to stay closed...Any idea?
When outside temp drops to 3 deg C (37 deg F) or below OBC autmatically displays outside temperature, regardless of what you set it to or what it was set last time and car beeps.
The reason for that to warn driver that outside temperature dropped to the point, that ice can forme on the road surface at certain atmosferic conditions, like bridges, open roads with strong wind, etc....
The fact that outside temperature displayed is -40 deg C (or F) most likely means of a damaged sensor(s) behind splash guard in wheel well. Unless it is really that cold in June, where you live...
It is probable, that your're having problem with your AC, I think outside temp is factored in the logic of AC.
If it is reading -40 degrees all the time the outside temp sensor is most likely toast. It is behind a splash guard on the drivers side, if i remember right. It can sometimes get ripped off in a bad pothole or it may just have gone out. The part is not that expensive and easily replaced.
