VW, Audi in Canada Halting Sales of TDI Cars Following US Inquiry

My sentiments exactly! While BMW diesels were pronounced to be using the desired method of pollution and emission control, I think VW will be able to rectify this by modding their software codes to super-lean running all the time, and more injection of DEF. There goes the neighborhood! The downside will be, I believe, that VW power and acceleration in their diesels will be reduced significantly, making these even bigger dogs than they already are. And if you can't run with the big dogs, stay on the porch. I'm amazed that more of these green-weenie eco-friendly squirrel-diesel lovers haven't spoken up to defend their realm.

@highdesertcat Ford and GM are probably the only auto makers selling diesels in the USA with throughly tested Emissions that meet standards.

@highdesertcat I have a TDI. Basically I feel there isn't enough info...very strange that the V6 TDIs can pass but the 2 liter engines can not. Just in terms of smells from the exhaust the car is better than a gasoline car (NO is odorless though). I need to see data to understand what the real problem is, so far it is just antiVAG bile and politics and no data. Does this have something to do with active regeneration of the DPF or certain types of engine load? WOT acceleration up hills? Cruising on the highway? People are airing opinions but the data is withheld. In my opinion this is nothing compared to the death-causing GM and Toyota cover ups, those were heinous. I mean, in terms of VAG lying to the US government...*shrug*, it is just a grotesque collection of sophists and nominalists. What does honesty have to do with US politics? It seems like emissions have come down 50% in a decade on production diesels, if they can't match the 70% reduction asked for by the EPA yet due to tech problems I can sympathize. It's hard to invent things and put them into practice cost effectively. Personally, as long as I can still buy diesel, the ECU is easily remapped if need be. Maybe it will hurt resale-- we'll see.

@manny_c44 The EPA's willing to work with companies, though. Navistar was working on a fancy EGR system but it wasn't ready in time; they asked the EPA and got a waiver for several years to get it working. They weren't able to make the system work, so they gave up and paid a pre-agreed fine for selling non-compliant engines (and then started selling urea-based systems like most other diesel manufacturers). Buyers sued them for the failure, but the EPA's behavior wasn't bad.

I suspect this is true, though VW might be the only one doing it in the U.S. The initial study that snowballed into discovering VW's scheme showed most clean diesels in Europe producing far more NOx in actual driving than in testing: http://www.thetruthaboutcars.com/2015/04/report-clean-diesel-nox-levels-exceed-european-us-standards/ I'm still a bit confused about why 2.0L 4 cylinders would have these issues but the 3.0L V6 TDI engines seem okay. Do the 4 cylinders just not produce enough heat or something?

@manny_c44 I agree the Toyota and GM cover-up was way worse then any Emissions issue. And people still love there Toyotas even as the death toll increased, Sales went up. All perception in auto sales.

@derekson The 3.0s all have urea injection AFAIK. With urea injection it's actually possible to meet the standards without tricks.

@dal20402 Several of the four cylinder models listed have AdBlue as well though. Specifically the 2015 Jetta and Golf models and the 2014-5 Passats all have AdBlue. I believe the 2012-13 Passat did as well but those were the generation 2 EA288 rather than generation 3.

I can only imagine that the CEAA (Canadian EPA) will be sidling up to VW for some fine money pretty soon as well. As will pretty much every other environmental agency, everywhere, eventually. Unlike some who seem to be downplaying the significance of this to VW, I fully expect that this incident will eventually result in a sale or bankruptcy of VW. At some level it's an issue of trust, and VW has now openly demonstrated that they are deeply indifferent to the health and well being of their customers & society. The ill will that has already come of this will take generations to repair.

That result is actually fair, because Canada has far fewer places than the US where the increased NOx emissions will have the potential to significantly worsen air quality-related public health issues. There is no equivalent in Canada to LA or Phoenix or Houston. Calgary comes the closest and isn't nearly as bad.
