Volkswagen is responding to EPA accusations saying that their 3-liter diesel engines are clean and are not equipped with a defeat device.

Earlier in the day, the U.S. Environmental Protection Agency said that numerous 3.0-liter V6 TDI engines made by the Volkswagen Group have been fitted with the emissions defeat device which is already affecting almost 500,000 TDIs.

The German brand issued the following statement vehemently denying the accusations:

“The United States Environmental Protection Agency (EPA) informed Volkswagen Aktiengesellschaft on Monday that vehicles with V6 TDI engines had a software function which had not been adequately described in the application process. 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. Volkswagen will cooperate fully with the EPA clarify this matter in its entirety.”

The announcement was made by Volkswagen AG and chances are Audi and Porsche will release their own stories too. There are numerous vehicles equipped with the 3.0 TDI diesel burner and these include the Audi Q5, A6, A7, A8, Volkswagen Touareg and Porsche Cayenne, which have been sold in the U.S., in the 2014-2016 model years.

“Playing” with the emissions test of this unit can be an even bigger hit for Volkswagen, because this engine is extremely popular across the Old Continent and it would have to be added to the rest of the “dieselgate” scandal.
