I cannot claim that you are wrong, and discussion is always a good thing.
My point above was from a performance point of view.
However, I will briefly mention that BMW's 2nd generation of diesel emissions equipment has been far more reliable than the first gen in the USA. No SCR tank issues as the early gen, and much better control, as well as very low emissions levels. The 328d is certified ULEVII, with emissions levels actually meeting SULEV guidelines (minus the required 120k mile warranty on all components).
There are far less issues, and while it's not perfect, most if not all the major problem areas have been covered by recalls or extended warranties.
This includes:
-the EGR cooler poor internal welds (recall/fix)
-NOx sensors are covered to 120k miles 10yr
-particulate matter sensor is now covered
Now, where I live, people find blowing heavy black smoke from their tailpipes an amusement, so I will not go into that great debate. People that want to delete will.
The equipment has definitely improved, however.
