I've been wanting to have the MPPK installed on my 14 435 (would be a dealer install) but these threads have me very concerned that I might incur a lot of headaches, especially since I have a 2014. It sure would be great to get some inside knowledge from a BMW tech or insider on how extensive the issues are for the new MPPK parts/software update. My dealer has not installed any yet so they have no experience with it (although they did a great job with my M performance brake kit install which was also a first for them).
