I first noticed that the A/C in my 2006 330i was not very effective, and it was bad in my 07' E70 and pretty bad in the 08' E70 too.

In general, new BMW A/C is not as strong, cold or even as say MBZ or most American cars. Porsche too has pretty weak A/C.

I think the problem is, once again, software related. Why should we have to worry about setting the Climate Control to Soft, Medium or Intensive? Why should we have to worry about adding little blue bars, or red bars in the climate 'fine tuning' i-Drive settings? Why not just have AUTO, plain AUTO setting for the climate controls with no sub-settings or fine tuning, like all other high end luxury cars? If you want to override the AUTO setting with stronger or weaker air flow, then (like always in the past) manually change the fan button.

Our 2004 X5 4.4i & 4.8is, the 2005 M3, both 2004 330cic, the 325i wagon and the Z8 all have strong, cold A/C. My last "new model" BMWs have all had bad A/C. Especially during hot weather, the cabin was never totally comfortable, and the Auto setting always provides too weak of a flow.
