M2 was driven in Sport 99% with DSC fully engaged.
M2C was set up with M1=Sport and M2=Sport+ w/MDM.
Driving home in the M2C with M2 settings from work one afternoon, as I was going around a turn like I have in the M2 for 16,000 miles and in the M2C for ~ 3,000 miles. The rear of the car suddenly and violently snapped toward the P/S. I corrected and the car straightened out immediately. If the DSC was off, I'm certain the rear would have contacted the curb in a very bad way.
I've played it over and over in my head and looked at this turn again and again since and I cannot figure out what happened. The only thing, that could possibly have caused it was a very small ~6" metal cover (not manhole cover size).
On the street, I don't even use MDM anymore. It's just not worth it.
