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...
