From my prior experience with CIC system (prior gen) and CCC (2 gens old) the answer is "it depends". In the past it depended on the software version number and the part's version number. BMW does some funky things when they update software and parts. They roll it out sometimes in piecemeal with fragmented compatibility.

Case in point, a popular mod back in 2009 was to install the CIC controller onto a CCC system. It worked as a plug and play for softwares in cars built after 4/2008, but didn't for any CCC based cars prior to April 2008, and IIRC, only if you use a certain set of updated controllers.

So that's why Nelson, a coder who specializes in these things can you tell. BPMSport can also help out on this question.

But you didn't answer the question. What "update" is it that you want? If it's a map update, 3rd party vendors can do it for you for cheaper and may be able to allow you to retain your updated controller. I'm not aware of a BMW dealer willing to just update the base idrive software without any known issues, same with DME/ECU too.
