That was then - Euro 6 is now. Today the EU only allows 0.08 g/km NOx

The fix for NOx is pretty easy - inject more and more DEF. VW was the only manufacturer not using SCR on their diesel vehicles in the US - which should have been a red flag for regulators. VW didn't add SCR to their 2.0 TDI until 2015.

Mercedes and BMW were using SCR on all of their US diesels from 2009.
