According to a Notice of Violation from the United States Environmental Protection Agency, VW group’s implementation of a defeat device in its diesel engines was not limited to just Volkswagen branded products. According to documents released today by the EPA alleges “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.”

This includes about 10,000 new vehicles sold in the U.S.; the 2014 Volkswagen Touareg, the 2015 Porsche Cayenne, and the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L, and Q5. All are equipped with a recently developed 3.0 liter diesel engine that does not meet emissions standards.

If you are any owner of any of these luxury products, stay tuned. We have contacted executives from VW, Porsche and Audi and will have more information on what they have to say about these recent developments and what it means for your car.

UPDATE
While this sheds little light on the situation, Porsche has issued the following statement regarding these latest accusations. “Late this morning, Porsche Cars North America received a notice of violation from the United States Environmental Protection Agency (EPA) regarding the 2015 Porsche Cayenne Diesel. We are surprised to learn this information. Until this notice, all of our information was that the Porsche Cayenne Diesel is fully compliant. We will cooperate fully with all relevant authorities.”
