He said in all the years only 3 cars....2 DCT & 1 Manual ('15, '16, '18 so all S55 M3/M4s). All tuned, but what level of tune I dont know. He also indicated even if the crankhub slipped the chances of needing a whole new engine are slim. His words...
They aren't interference engines. So even if it fully Jumps timing it won't need an engine.

That's the opinion of one service tech at one dealership. Most people who are tuned and have something as big as a crank hub failure will not even go to the dealership because they won't be able to install an aftermarket crank hub. The former BMW master tech at the shop I got my PPI done at told me he had gotten in 3 in the past year and has had many come in over the years. He was in the camp of the DCT aggressively shifting being the cause of
most spun crank hubs (even stock). I've heard several independent shops echo this... could they just be trying to up-sell people on an unneeded mod? Sure. But this shop strongly recommended against doing it and instead just buying an extended warranty if I was enjoying the car stock, which added credibility to his statement.
I ended up doing the crank hub recently because I'm tuned and $3-4k insurance for a possible $15k+ months long headache sounds good in my book.

Plug in an OBDII to ethernet cable or WIFI ENET adapter and connect to BM3 or MHD. They will tell you if a bench unlock is needed. In my experience it seems like 03/2019 manufacture date was the cutoff for not needing a bench unlock, but I've head of some pre 03/19's getting locked by the dealers if you bring them in to do a software update.
