The EPA is putting VW on notice again for even more violations, this time specifically for vehicles using 3.0 liter diesel engines. After the initial confirmation of issues with VW Group diesel vehicles using its 2.0 liter diesel engines from 2008-14 back on September 18th, the California Air Resources Board sent out a notice on September 25th to all manufacturers informing them that additional testing would be performed. The EPA has redefined its emissions test methods specifically to look for any emissions defeat devices and it was this change that helped them find the additional VW violations in the second round of testing.

The results are in and it’s not looking good for the VW Group as the EPA sent out a Notice of Violation (NOV) for issues with VW, Audi and Porsche diesel vehicles using said 3.0 liter diesel engine in model years 2014-2016 for basically the same workaround:

“The NOV alleges that VW developed and installed a defeat device in certain VW, Audi and Porsche light duty diesel vehicles equipped with 3.0 liter engines for model years (MY) 2014 through 2016 that increases emissions of nitrogen oxide (NOx) up to nine times EPA’s standard.”

The recent announcement includes some juicy details about the actual emissions defeat protocol the cars use to stay within limits while being tested.  Reading through it leaves me feeling gross and not because of the extra soot in the air…it just feels like such a slimy way to operate:

“When the vehicle senses that it is undergoing a federal emissions test procedure, it operates in a low NOx “temperature conditioning” mode. Under that mode, the vehicle meets emission standards. At exactly one second after the completion of the initial phases of the standard test procedure, the vehicle immediately changes a number of operating parameters that increase NOx emissions and indicates in the software that it is transitioning to “normal mode,” where emissions of NOx increase up to nine times the EPA standard, depending on the vehicle and type of driving conditions. In other tests where the vehicle does not experience driving conditions similar to the start of the federal test procedure, the emissions are higher from the start, consistent with “normal mode.”

VW has been in the news a lot of late and in this case, it is not thinking that “any news is good news” as this is another huge hit against the brand and unfortunate for all of us. Diesel emissions are known for their high concentration of Particulate Matter (PM) and has been linked to higher cancer rates. A recent California study showed a correlation between decreases in diesel emissions and lower cancer rates which makes this second batch of VW violations that much worse. The EPA news release provides more detail about the harmful health effects of diesel exhaust:

“NOx pollution contributes to harmful ground-level ozone and fine particulate matter. Exposure to these pollutants has been linked with a range of serious health effects, including increased asthma attacks and other respiratory illnesses. Exposure to ozone and particulate matter has also been associated with premature death due to respiratory-related or cardiovascular-related effects. Children, the elderly, and people with pre-existing respiratory disease are particularly at risk of health effects from exposure to these pollutants.”

With the initial announcement in September, the possible fines in the US alone were staggering and this announcement just ups the ante.  VW will have an opportunity to respond to these new allegations and in addition to a likely mandate to fix the excess emissions in their vehicles out on the road, may be liable for civil charges.

The full list of VW vehicles now affected is as follows (from the EPA):

Affected 2.0 liter diesel models include:

  • Jetta (MY 2009 – 2015)
  • Jetta Sportwagen (MY 2009-2014)
  • Beetle (MY 2012 – 2015)
  • Beetle Convertible (MY 2012-2015)
  • Audi A3 (MY 2010 – 2015)
  • Golf (MY 2010 – 2015)
  • Golf Sportwagen (MY 2015)
  • Passat (MY 2012-2015)

Affected 3.0 liter diesel models include:

  • Volkswagen Touareg (MY 2014)
  • Porsche Cayenne (MY 2015)
  • Audi A6 Quattro (MY 2016)
  • Audi A7 Quattro (MY 2016)
  • Audi A8 (MY 2016)
  • Audi Q5 (MY 2016)

  • Ok, now you KNOW that VW knew that there was a hack on the 3 liter, also. When they got caught with their hand in the cookie jar on the 2 liter. Why, oh why, didn’t the fess up to all the diesel cheating they were doing. Surely that would have been better for their brand, than this!

    • With the 2 liter AND 3 liter it looks more like a corporate decision.

      • I thought they had proved it was intentional back with the 2 liter engines which took it to a whole different level. It’s one thing to get caught but it’s a whole different ballgame when you get caught doing something on purpose.

        • I think @sjc_1:disqus meant (and I agree) that seeing the same cheat on multiple engines and brands points to something bigger than “just a few rogue engineers”.

  • The HOPE they wouldn’t get caught with any further violations was worth the risk. Now the premium brands, Audi and Porsche are affected. Would have been better to keep the vilations on the VW moniker. Not everyone knows VW is the parent company.

    All the best,

    • I drove home next to a brand new (assuming 2015 or 2016) Porsche Cayenne Diesel. I almost felt bad for the driver…people are fairly critical of that type of thing though it’s obviously not her fault. Bummer…

  • I think it’s been clearly proven now that ‘Clean Diesel’ is as much of an oxymoron as ‘Jumbo Shrimp’.

    • I’m hoping this is a big enough stain on Diesel overall that people start moving away from it and based on what we’re seeing in the UK already, that may be the case 🙂

  • In the past (decades ago) I owned a VW diesel and later a Toyota diesel. I did like the mileage I did get, but never liked the smoke when cold and the smell of diesel, for pumping fuel, had to keep a rubber glove otherwise the smell on my hand was bad.

  • I hope they fine this crap “success-story” company to oblivion and tighten the regulations even further.

  • Didn’t VW recently announce there was no cheat device on their 2015 and 2016 models. What gets me is their arrogance. I’m with Matt, why not fess up to all of it. At this point, we need some kind of grass roots action to boycott buying all VWs. Get posters designed and available for download. Print and post them at work, hangouts, public places.

  • The consumer can no longer trust German product with the same reliance as before. They know now that Germany never had the technology or the expertise in engineering. German Snake oil sold well, propaganda.

    How much did the German government know, targeting USA auto manufacturing driving anti-competitive green labelling, against local manufacturing compliance.

  • VW/Audi/Porsche could be bankrupted by fines and consumer disgust. Bad news for Deutschland, good news for Tesla and Murica.

  • It now may be too late for VW, at least in the US. They (pardon the crude euphemism) really screwed the pooch with all this diesel lying. Beyond the fact that they’ve been bragging about being an electric car “leader” for far too long without really showing much more than unobtainium concept cars and a glacial rollout of the eGolf in true compliance fashion, I don’t think anyone is going to trust them if and when they declare they have a superior battery technology, even if they really do.

    Too bad . . . I would have loved to see the e-UP available in the US, but their stuffy upscale North American marketing people nixed that idea several years ago . . .
