Superseded by:

33108090473 (07/15/2016 — ), nonexchangeable retrospectively


What this mean? 33108090473 fit my vehicle? Maybe is something like bmw upgraded someting in differential interior and changed the code of part?

The latest part # 33-10-8-090-473 is supposed to fit the 2015 M4 so yes the part you found should fit.
No, not exactly. The vehicle in question is an M4 with a build date of 05/2015. Based on Realoem here:
http://www.realoem.com/bmw/enUS/show...diagId=33_1838

01 Final drive with differential 1 04/2014 07/2016 33108090464

So from this, it tells you that part #464 works for vehicles built from 04/2014 up to 07/2016

While 464 is superceded by these two:

33108047142 (07/01/2016 — ), nonexchangeable retrospectively
33108090473 (07/15/2016 — ), nonexchangeable retrospectively

Your vehicle falls out of the build dates indicated

So with my 2017 with a build date of 10/2016, for example, #473 works for me, as indicated:
01 Final drive with differential I=3,46 1 07/2016 33108090473


EXCHANGEABLE RETROSPECTIVELY means "if your vehicle is within the indicated date range, then the part WILL work"

NONEXCHANGEABLE RETROSPECTIVELY means "if your vehicle is NOT within the indicated date range, the part will NOT work"

I think that's it...this is confusing so if I got it wrong, someone definitely should correct me but that's how I interpreted it
