I just today listened to the BBC Bottom Line Special [1] on this, and their guests, one who used to run Jaguar, and an expert on VW, don't buy it. Their argument is that the engineers in VW could have done a proper job, but the technology would add another $500 to each vehicle, and VW must have been looking for a way not to spend the $500. And all the other VW engineers would ask "How did you do it?". [1] http://www.bbc.co.uk/programmes/b06jt518 9mins 15 onward |

The idea was that only DEP and EGR was needed for the smaller TDIs simply because they burned less fuel so produced less emissions across the board. That's not enough to meet current limits, but VW claimed they had better CDI that solved it. They got many patents related to that and other companies even licensed it. But how did they get such good performance, the lines was due to the turbo and the tests did not really spool that all that much.
Turns-out it was baloney, but that's how they explained it at least.
