My Ride: 2005 BMW 545i, Silver Grey, Sport Package, R. Shades, Cold Pkg, Sat. Rad., Prem. Sound.
On my 05 545i, it claims automatic climate control. If I set the AC in iDrive on high, the blower blows high . . . likewise for medium and low. Hence the temperature knobs DO NOT control the blower speed.
BMW engineers are too smart for their own kind. I do not know of any automaker that claims automatic climate control THIS WAY.
My previous Nissan Maxima, Lexus LS400, etc. and any other climate control system works very logically . . . set the temperature I want, e.g. 74, and the AC adjusts the blower and temperature automatically to quickly get 74 F in the car.
For BMW, it's better to use the manual fan knob and turn the temperature knob. Hmmmmm. . . . . where's the "smart system?" Software updates?
Another note, the AC comes on every time I start the car even if I turned it off the last time? Thanks, sometimes, I prefer to turn the A/C on myself.

The vent settings in idrive set the TEMPERATURE of the DASH vents. Not the overall cabin temperature which is controlled automatically based on your preset temperature selection. It's actually a fairly sophisticated system, but not easy to understand. And you don't.

Okay, here's how the car really works....
First, as with any automatic climate control system, the temperature selectors will adjust the fan speed higher or lower until the desired temperature is reached. It's possible to provide small adjustments to the temperature of the air coming out of the vents but usually, as in the case of A/C in summer, the temperature is on "full cold" and the fan speed is used to chase the temperature.
Now, here's where the confusion starts. The three settings in iDrive (Low/Medium/High) only control how agressively the car chases the desired temperature.
For example, if the iDrive setting is on "medium" and the interior of the car is one degree away from the desired (set) temperature, the car will adjust the fan speed accordingly to find a good balance between quickly cooling the car down one degree while remaining relatively quiet in doing so.
If the same situation occured while the iDrive setting was on "high," the car would more agressively blow the fan to get to the desired temperature (essentially sacrificing a quiet cabin in exchange for reaching the set temperature faster.) Obviously, the exact opposite is true if iDrive is set to "low" -- the car will take longer to reach the temperature but it will do so very quietly.
These three settings used to be called something else in earlier versions of the software. They used words like "more agressive" "normal" and "less agressive" (I can't remember the exact words.) (edit: I looked it up in the 2004 owner's manual and it says: "intense," "medium," and "soft" on page 93/.pdf page 95. In TIS, it says the choices are: "intensive," "medium," and "gentle" but it also mentions a fourth setting called "convertible" which is selectable only when the convertible top is open. Anyone with a 6-series convertible care to confirm that setting?)
Hope that clears things up a bit. One thing's for sure, the car clearly has an automatic climate control system and as far as I'm concerned, it works as good or better than many other systems I've used. (For example, the E60's system adjusts humidity levels as well as temperature.)

I think the A/C works fine, but I don't like how you have to adjust both temperature knobs.

As for the automatic, all i can say it trully works as an automatic. (controlling humidity, temperature, speed) AND i noticed that if i'm driving on a normal road, hot outside and suddenly change direction and the sun is in my windscreen now, the air changes in intensity and ari outlets accordingly not to feel too much the heat from the sun. That's a nice thing...automatic as the sun rays hit the windscrren

BMW engineers are too smart for their own kind. I do not know of any automaker that claims automatic climate control THIS WAY.
My previous Nissan Maxima, Lexus LS400, etc. and any other climate control system works very logically . . . set the temperature I want, e.g. 74, and the AC adjusts the blower and temperature automatically to quickly get 74 F in the car.
For BMW, it's better to use the manual fan knob and turn the temperature knob. Hmmmmm. . . . . where's the "smart system?" Software updates?
Another note, the AC comes on every time I start the car even if I turned it off the last time? Thanks, sometimes, I prefer to turn the A/C on myself.
