Computer Malfunction? Help?

[EnvyM3]

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?

I'm pretty sure that when temp is below -38 the car normally beeps at startup to warn of cold temperatures and it automatically switches the heated rear screen on....maybe the beep is linked.

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.

I had an outside temperature gauge go out on a 94 Dodge Caravan. Didn't seem like it was that expensive to replace, just a thought.

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.

Anyone know if the outside temp sensor is covered by manufacturers warranty?

If it is faulty it should be covered by the 4yr/50K mile warranty, if it is missing you will most likely have to pay.

remote chance: wire unhooked. it would show minimum temp as it sees no res. mach5: am i smoking crack on this one?

No you are not smoking crack. The wire could be unhooked and you would get the min. reading on -40. It is however unlikely that the wire would fall off.
