I believe there is an open recall for that issue.
The dealership claims they've performed the recall for the issue even though they can't seem to produce proper records of it.

Also - I noticed something else about my brake issue. It seems that the issue appears when the weather is below freezing. In warmer temperatures my breaks function perfectly. I get the feeling that it may just be a seal or hose some where that's expanding/contracting with the temperature changes as I doubt any metals would expand/contract enough with a 10 degree difference.

As it stands - I think I'm going to take it to an independent BMW mechanic to diagnose it. If it turns out to be the recall issue then I'll yell and scream at the dealership until they fix it properly - if not, I'd be better off at the indy anyways.
