Another poster already noted - there is no difference except for DSC being off.
DSC is never off unless you manually turn it off, which you do by pressing the traction button above the drive-mode button. Sport+ is the same as Sport with the addition that DTC is turned on (Dynamic Traction Control). It allows for some more wheel spin before DSC comes to the rescue.
Can u even get adaptive M supsension with Xdrive? Im pretty sure u canīt get the lower M suspension on an xdrive and therefore you shouldnt be able to get the M adaptive. Correct me if Iīm wrong.
