A second wave of “defeat device” accusations from the EPA has landed on Volkswagen’s head. This time, the emissions scandal spreads to the company’s 3.0 L V6 diesel motors found in 2014 Touareg, 2015 Porsche Cayenne V6 Diesel, and 2016 Audi A6, A7, A8, A8 L, and Q5 Diesel models.
This emissions violation is a separate case from the one announced on September 18th, which involves 482,000 Volkswagen Group cars powered by the 2.0 L 4-cylinder engines from 2009-2015.
This new report finds that emissions cheating device was found in roughly 10,000 Volkswagen Touareg/Porsche Cayenne Diesel and “unknown” amount of Audi diesel models.
Volkswagen, in a statement from its Wolfsburg headquarters, denied any speculations about it purposely cheating the emissions testing procedures with its V6 diesel engine. The company officials in the statement said “Volkswagen AG wishes to emphasize that no software has been installed in the 3 liter V6 diesel power units to alter emissions characteristics in a forbidden manner.” They also said “Volkswagen will cooperate fully with the EPA to clarify this matter in its entirety.”
In a separate statement, Porsche Cars North America officials said “we are surprised to learn this information”, and “until this notice, all of our information was that the Porsche Cayenne Diesel is fully complaint.”
In three lab tests conducted by California Air Resource Board (CARB) and Environment Canada, the EPA stated that cars equipped with the 3.0 L V6 diesel engines emitted up to nine times more than the allowable nitrogen-oxide (NOx) emissions when the software detected that the vehicle was not being tested. This, in comparison, is much lesser than the nitrogen-oxide emissions released by the company’s 2.0 L TDI 4-cylinder engines, which varied between 10 to 40 times greater than the legal amount.
As of this writing, the EPA has not issued any formal penalties and the National Highway Traffic Safety Administration (NHTSA) have not conducted any recalls related to these diesel models.
