In a statement, Volkswagen said “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-litre 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 engine in question can be found on select 2014 Volkswagen Touareg models as well as some 2015 Porsche Cayennes and the 2016 Audi A6, A7, A8, A8L and Q5 models. It is reported that around 10,000 of these cars currently reside in the United States with the engine in question.
In a similar vein to its parent company, Porsche has refuted the allegations and says it will cooperate with the authorities.
“Late this morning, Porsche Cars North America, Inc. 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. Porsche Cars North America will cooperate fully with all relevant authorities.”
