VW new the need was coming. Diesel fuel had to be cleaned up well in advance (<15ppm sulfur) well before the 2007 model year to support the technologies required for that year. There are no 2003-2006 Diesel cars here.

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...
