It's an improvement that I see the majority of pepole didnt' fully understand, including me, I discovered it here!!!
Got it explained very well. In order to satisfy the majority of users, the AUTO position has now the option to LIMIT the maximum air speed the system can reach. That's the meaning of the ventilation selection when in AUTO mode. This means you can easily set it to the max and the car will vent with max power up until it's close to the temperature set, then will slow down as in "Normal" operation. If you set the vent to the minimum, the car will blow much more gently, clearly requiring much longer time to reach the desired temperature.
You just need to find your personal setting and then you're done. For example I didn't like it with the previous 320d I had that was too strong for me, I found a good setting with the three bars (more or less in the middle, it's a five-step setting if I remember correctly)
