I didn't post it, but yes it is. And the VW does it without any urea injection system.

I don't know, but it may have something to do with the particulate filter... here's the quote from VW's press release:

 

Could be because of vehicle / engine size too. I read that larger VW TDI's like the Passat and Touareg will use a urea system.

The Touareg maybe... but the Passat has always used the same diesel engine that the Jetta/Golf has.

 

The most recent Passat and Jetta TDI's had different engines here. (are you in Europe?) Passat was a 2L, Jetta was the popular 1.9L. The new Jetta TDI will have a 2L common rail engine. I can't remember what the next Passat TDI will have. Perhaps the extra fuel needed to move the heavier Passat makes more NOx than the Jetta catalytic converter system can process.

Ack, you're right... the passat was a 2L, which is the same size as the new TDI engine in the Jetta. And the new engine makes more power than either old engine, so I don't see why it couldn't be used in the new Passat.

That was most likely me you're quoting.

The 2007 Mercedes Benz E320 CDI meets Tier 2 Bin 5 emission requirements. The reason that Volkswagen withdrew their diesels from the North American market in 2007 is because they use a proprietary Pumpe-Düse injection technology. All the other automakers use common-rail injection technology from 3rd party suppliers like Bosch. VW’s PD injection system will not meet the new North American emission requirements though it still meets the EU’s current regulations. For 2008, VW is switching to a common-rail system.

M-B, BMW, and VW have announced an agreement that they will share the BlueTech technology first introduced by M-B in the new E-Class. The Europeans are looking to use there expertise in diesel technology to counter the Japanese hybrid technology in the quest to improve fuel economy.

For those that will say that T2-Bin5 is a step back, dirty, just meeting the bare minimum of emission requirements; you’re right. But you also need to look at what other manufacturers are just meeting the bare minimum. For the 44 non-CARB states, all of Toyota’s cars only meet T2-Bin5. The E-Class also gets 20% better fuel economy than a comparable V6 Camry. (E-Class 26/37 mpg vs Camry 22/31 mpg)

I've had a chance to drive a E320 CDI wagon in Europe and it is a fantastic car. It has way more power and size than what I would need but the E-Class is a joy to drive on the Autobahn. It also returned fuel mileage in the mid 30's averaging 120 mph!
