The easiest test is to see if you have inside tire spin accelerating hard in 2nd gear around a tight corner. My M5 LSD discs were shot by ~50k miles but that included many autox launches on R-comps, track days, etc. Simply powering out of a 2nd gear turn would burn the inside rear tire just like an open diff. DSC off of course.
