SCR can be gutted / replaced. Can also remove nozzle, remove swirl, remove tank. Need coding to turn off spray.
Tuners are various - Bob at BPC, Jarek (US rep is AA Rodriguez), others
Look up post about alphabet delete. Look at BPC posts and posts containing Jarek's name.

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.

DFP/SCR, EGR block, Swirl flap delete, BPC tune, Down pipe, FMIC upgrade.
When/if something breaks - plan to replace the item with a performance part and mod the car a little at a time.

This literally sums up almost, if not all my questions. I will continue to do my due diligence and read, read, read.
This car would be my daily so I'm just trying to research ahead of time to make sure I'm not considering a problem-child car. My E90 330xi has been absolutely excellent from a reliability stand point (knocks on wood), but I've been considering something with a little more power. I decided against the 335i due to the constant lingering turbo/HPFP issues. My dad has always been a huge diesel fan (owned many VW diesels as well as currently owning a manual converted E28 524d) so I thought I'd consider a 335d (dat torque doe).
