The HVAC/Automatic Climate in my 2007 & 2008 E70s drove me mad. Either too warm, too cold, too strong, too weak..... It was just never right, and it made me mental fidgeting via iDrive... setting things warmer/red or cooler/blue or up, down.... Argh!!!

In my new 2011 E70, I just leave the iDrive setting in the middle/neutral, set the AUTO to 70 or 72F (and I leave the recirculation on Automatic always). The car heats very well, evenly and quickly. When warm/hot, the car is quickly and efficiently cooled. I leave the blower intensity on Medium. I find soft is way too slow and Intensive is too loud and strong.

So far, the AUTO climate in my E70 is pretty excellent. Not as good as in the 2010 750, but a lot better than in our 2010 M6.
