This is interesting because I have not been following this thread and just now read it. A few weeks ago, as a result of a recurring intermittent CEL, the dealer provided the update. Took all day, and I had to reset just about everything after (radio stations, M buttons, preset buttons, etc).
I kept thinking something was wrong with the Sport+ throttle setting because it behaved a lot more like Sport on tip-in. No jerkiness whatsoever. I also thought the car seemed slower, mostly because of the lack of constant intervention. Then I read this. So there you go.
I don't feel a difference in suspension settings or ride, but I'm not super perceptive when it comes to that.
