It is possible the VW diesel would not pass all the newest tier 2, bin 1
standards ( NoX < 0.02gm/mi)  standards without Bluetec, which would
have meant no TDI sales for a few years. NoX is dependent on combustion
temps, controlling with EGR & fuel delivery is not effective enough to
meet the stricter US standards.
Injecting a fluid to control emissions and combustion temps has been
around for years, kind of odd turns out to be urea for diesels...
