The HAG215 M Sport diff design is based on the HAG225 diff used in a true M F97, but it is not the same part, although both employ the same active electromechanical approach.
Look for option code 2T4 M Sport Differential on the VIN to check the type of diff fitted.

and no matter how technically literate or capable the diff is... the M lite programming on the M40i will not allow it to properly operate like the X3M and do a true drift as the stability control will always try to straighten you out even if its entirely off... in the x3m it's an opposite approach to throw you into a turn and let you slide out of it
