Vw diesels have had EGR since before 2000. The MkV GT TDI era 125 kw cars were the first VWs with a combo NOX and DPF. The Mk 6 from 2009 has a pre NOX on top of the DPF, and the latest MK7 diesels have a much much bigger NOX. The Mk6 era was the first with high and low pressure EGR. We would be unlikely to have the US specific cheat software, but hey lets worry if and when it happens.Quote:

Do you happen to know what engine this has - is it the EA189 or EA288, and does it have EGR? I looked on the VW website and under fuel economy and emission control measures they only mention DPF, turbocharging, and Bluemotion technologies like stop-start/coasting/brake regeneration - no mention of EGR or SCR. Thanks!Quote:

Reported today that VW management should have a definitive list of ALL effected vehicles by early next week.
As far as the dealers are concerned, not before time as they remain in the dark still.
The European standard levels for NOx emissions is more than 2x the Californian standard. CAli appears to be trying to pave the way for Tesla and other electric car manufacturers by making it almost impossible for fossil fuel driven cars to reach the legal emissions level. Ford and Honda were also fined in 1998 for defeat devices. I think this is going to be widespread.Quote:

You guys have the engines as everyone else. Vw ain't gonna edit out code for one region like that.
From reading snippets here and there .. same car and same software sold here, USA, Europe etc.
What would be useful is finding out what the acceptable emissions/NOx standard is in Calfornia/USA vs Europe vs Australia.
It does say in some articles that in the recent tests that tailpipe readings were "10-40 times" over what was legal in the US.
So I expect euro emissions to only be ~15 times over.
Maybe Honda took their time in producing their diesel because it was such a difficult task producing a clean one without cheating.Quote:

These corporations are out to make a profit, bottom line. VW is no different in this respect from any of the other companies that have been caught in the past or will be caught in the future.Quote:

The only thing this debacle really shows is that yes, VW is a fallible corporation that will lie for money like all the others and no, laboratory emissions testing is not a good way to ensure manufacturers produce engines that run clean outside the laboratory.
