The Environmental Protection Agency said on Monday that it had found cheating software on more Volkswagen and Audi cars than previously disclosed and, for the first time, also found the illegal software in some Porsche models.
The agency says that Volkswagen installed a defeat device in certain Volkswagen, Audi and Porsche light-duty diesel vehicles equipped with 3.0-liter engines, for model years 2014 through 2016. It said these devices, meant to cheat on emissions testing, would increase the release of nitrogen oxide up to nine times the agency’s standard.
The E.P.A. said that the vehicles covered in its latest notice of violation are the diesel versions of the 2014 VW Touareg, the 2015 Porsche Cayenne, and the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5.
The new disclosure covers about 10,000 passenger cars already sold in the United States since the model year 2014. In addition, the violation notice from the agency covers an undisclosed number of 2016 vehicles.
The E.P.A. said in September that Volkswagen had installed cheating software on many of its 2.0-liter diesel cars, which turned on pollution controls when the cars were being tested. In day-to-day usage, however, the mandatory controls were turned off, providing the cars with better engine performance and fuel economy but emitting as much as 40 times the legal limit of nitrogen oxide, a pollutant linked to lung ailments.

The agency said Volkswagen would have to recall 482,000 cars in the United States once it came up with a way to fix its cars. Volkswagen has not yet disclosed how it will fix the cars.
The EPA found the additional defeat devices in new cars after it conducted new tests along with the California Air Resources Board and the regulatory group Environment Canada on all diesel cars after its announcement last month.
