Here are a few discussions on this topic (there are more).

Link 1.
Here is another link.
One more with almost direct evidence.
Here is a source also claiming no BER in the US.

In short, after reviewing all of the posts here and on other sites I would say that all NA model years of the M3 having BOTH features (AC and Alternator disengaging at high or WOT) is very debatable. It would be great to put this one to bed.
