Our new 328i with X-Drive is doing the same thing. We just got it out of break in mode, so I took it for an oil change (never hurts right?) and then wanted to open it up a bit and see how it handled. I usually drive my MINI in DTC mode just because it allows a bit more slip before the "nannies" kick in. So I go into DS transmission mode, sport mode on the drive selector, and when I go into DTC mode, it puts me back into comfort. So I thought oh, I'll just throw it back into Sport... Well that turns DTC off and DSC fully back on.
