Would someone please 'splain this climate control to me???!!!
 

First off, I have the auto climate control and I only use one key so this is not a programming issue. Why is it sometimes I get in the car and the settings are set to where I left them last and other times the settings revert back to the way they were before I changed them the last time I was in it. For example:

1) I get in and the air is set at 75F, blowing on my feet and at my face.
2) I decide to change it to 72F and blowing only on my feet.
3) I shut off the vehicle and leave for awhile
4) I come back and crank up the car

Sometimes it goes back to Step 1, sometimes it goes back to Step 2

Does it have something to do with how long I am gone, how long since I changed it, what??? I have had this car for over 2 years and still have not figured this out and yes, I have searched the manual a few times.

Thanks in advance!!!

Key memory?
Works for our keys.

Sounds to me like the climate control is figureing out what the temp is in your vehicle is after you have been away and then delivers what it thinks is best based on the temp you have chosen. To many variables at work i suppose.

Auto seems to work well for me although at times it's knows it's too hot in the vehicle and proceeds to cool things down quickly with high speed air.

Over all it works prettry good. I have to admit though that i have never seen any climate control work as good as my 1987 Fleetwood Cadillac. It flatout just worked no matter what the inside or outside tempt.

All this is while set in AUTO?

No, this is without the Auto button being on.

Not the key memory because I only use one key for my vehicle.

First, get another key in case you join the "ILMKITX" gang.
Even so, it is linked to the KM system and that has all sorts of funny quirks and foibles. It could be the problem.

Then without manually changing the vent position, I am lost too.:dunno:

Same problem here. Always left on auto, usually the temp is 72/73-driver/pass. Come back and sometimes both will be at 70, still auto. Same key.

Same thing happens to me. If I have had the same temp set at one setting for a while and I change it, the next time I start the X it goes back to the temp it's been at and not the new temp I put on recently. :dunno:

I'm suprised no one has used :rtfm: for all us lazy asses yet.

It always seems to works for us and we use two keys. Are you locking the vehicle each time? I think it only remembers the setting at the time of locking so if you make an adjustment but don't lock the vehicle it reverts to the setting it was at the last time it was locked with that key.

In the spring and fall when I roll with the windows down and sunroof open, I obviously turn off the A/C. I always have to turn it off again when I get back in the car (the first time after originally turning it off). The following time, it remembers the "off" setting, and stays off.

Have all of you guys locked the X after you left the vehicle? Locking with the remote saves the settings you had so they can be retreived next time you unlock the car with the remote. If you don't lock the car with the remote, the car may or may not remember the previous settings.

Yeah apparently there is some magic equation to get the AC to stay off. I always lock mine with the remote after getting out and 1 out of 5 times it remembers to keep the AC off. I have never understood why BMW does the "auto on AC" thing. Every BMW I've had has had this.

You can have partial auto settings, for instance if you do not like the fan speed, you can change it, but the auto climate control is still controlling where to send the air, ie which vents to use. Therefore, when you get out of the car and let it sit for a while, the climate control will still choose where to send the air.

:thumbup: I have another key, its just that we only use one of them.

First off, thanks again for you know what;)

And I HAVE read the manual more than once on this issue and I cannot find anything in there about it. Oh well, guess the X ISN'T perfect!!!
