CBU costs $1200 AFAIK. Search for the PDF with the SIB/TIS that describes symptoms and procedure. Not everyone has experienced the need to have it done, no matter what "everyone" says.
SCR tank and related NOx sensors are the most prevalent problem circa 100K-120K miles - don't think that anyone is going to avoid them. There are a couple DIY/fixes for a couple issues with SCR tank sensors. SCR tanks are $800-$1500 (not $7k.)
Engine and transmission are pretty solid; lots of people well over 100K with no problems. Don't see why they won't run 300K+.
Search terms: CBU, DPF, SCR (and/or DEF), NOx, EGR.
There is no sticky because the admins are strict about any promotion of illegal stuff, and every delete and tune are illegal. There are several posts both here and bimmerfest that answer your questions.
