Wow, i was going to start a thread myself about the climate control but was beaten to it.
I too find that on a hot day, say 90deg, I have to keep adjusting the controls.
I start at 68 and then move to 72 then its up to 78 just to get the fan to go to low mode.
I was wondering myself if something needs to be calibrated? If anyone gets info from a dealer on this, please pass it on... I agree that the A/C definitely pumps out cold air (much colder than my M3 did) but the constant adjusting is very annoying. Sort of defeats the whole climate control system....

at first when i had the G brand new back in november i thought the climate control was whack at a certain temp say 75 somtimes you get hot and sometimes you get cold depending on surrounding temps. To me this is counter intuitive if you never had auto climate before ie say in a toyota highlander if the round temp dial is in the blue you will never get hot air ever. The sometimes cold sometimes hot climate control did bother me quite a bit in the beginning...but now after several months ive found that if i leave it on auto at 75 most of the time it does what i want and for the times it doesnt if adjust the fan speed that will make it more cold or less cold, still not the greatest but im at least used to it. I prefer if it would work that i Always want cold air put out cold air and if i want hot air ill turn up the dial but alas the climate has a mind of its own for better or worse.

Yeah, I'm starting to think that the climate control system is calibrated too high, or is it too low.
It was showing 94deg outside on the G's temp display today, and I was able to set the temp to Auto 80degs
and it was keeping me perfectly cool with fan speed 3. The higher you tune the temp, the lower the fan speed.
I wouldn't say the climate control is "not very good" as original poster stated, but that it just needs some calibration and adjustment. I wonder if there will be a TSB for this if people start to and continue to complain about this issue.

The system is plenty strong enough, but clearly inaccurate.
I have the same problem here. If I set mine at 73, it is waaaayyy too cold, that feels like 67.
It shouldn't be that far off, there should be a simple computer adjustment.
While its not a huge deal, it is unacceptable and should be properly calibrated.
Otherwise, what is the point of having a digital climate control if it is highly inaccurate and requires constant adjustment?

1. Turn ignition switch ON.
2. Set in self-diagnosis mode as follows. Within 10 seconds after starting engine (ignition switch is turned ON.), press climate control OFF switch for at least 5 seconds.
3. Press fan (UP: +) switch to set system in auxiliary mode.
3. Display shows “61” in auxiliary mechanism. It takes approximately 3 seconds to enable setting operation.
4. Turn temperature control dial (driver side) as desired. Temperature will change at a rate of 0.5°C (1.0°F) each time a dial is turned.
This was taken from SM pages HAC-10 & HAC-44

So in plain english, if my climate control is currently too cold (in other words, when it is set at 75 it feels more like 70), I need to turn temperature UP by this procedure?
It seems like most of us here are having the problem of the actual temperature being too lower as compared to the setting.
What is this going to do to heat settings?
It is too warm now, but if I set my heat to 72 right now, would it be heating to 78? Is that how this function is working?
