BMWNA did come out and look at it, concluded that the diff bolt failure shouldn't have happened and approved the full diff and subframe replacement under warranty. Point is you're probably allowed a couple of "mulligans" with MT as long as it's not overly excessive (absolute amount and # of times), and with DCT probably a lot less to worry about.
I wonder if there is preventative maintenance for this diff bolt issue. I'm going to get 295/30/19's because I think it will reduce wheel hop that I get with my 265/35/19's on an 11" wheel. I'm terrified of this happening to me. 47K on the clock now and so far so good (even with 500+ times to 8,800 RPM)...
But then again I rarely launch the car.. Reminds me of the E46 subframe issues.. ridiculous to have fear to drive the car the way it's meant to be driven! I just love this car more than any other car I've had in my life and don't want to hurt it..
