Possible fix for idle issues with AC on.
I fixed my problem by using the BMW Foxwell BMW Multifunction tool (any scanner that can program BMW will work) and adjusting the idle speed to the max setting. I think there were 4 different conditional settings. Some were set at 50 versus 150 (Range being (negative 150 to Positive 150). After setting all to 150 the problem was reduced so that it was not really a problem. No jerking just some slight RPM bounce with AC on. Not sure this will work for everyone but it worked for me. Easy fix. BTW - I did not notice an increased idle speed after the fix.
