The U.S. Environmental Protection Agency said on Monday that it appears to have discovered software that cheats during emissions tests in additional Volkswagen and Audi cars as well as in one of the automaker’s Porsche models, but the embattled automaker fired back disputing the new claims.

The latest notice of violation of the Clean Air Act concerned Volkswagen Group’s models with V-6 diesel engines and that these “also employ software that circumvents EPA emissions standards.”

Volkswagen issued a statement saying “no software has been installed in the 3-liter V6 diesel power units to alter emissions characteristics in a forbidden manner.”

Porsche was equally surprised. “We are surprised to learn this information,” said Porsche in a statement. “Until this notice, all of our information was that the Porsche Cayenne Diesel is fully compliant.”“VW has once again failed its obligation to comply with the law that protects clean air for all Americans,” said Cynthia Giles, the assistant administrator for EPA’s Office of Enforcement and Compliance Assurance, also in a statement.The Wolfsburg-based automaker said it will “cooperate fully with the EPA clarify this matter in its entirety.”

The EPA issued a similar notice concerning four-cylinder Volkswagen and Audi diesel cars from model years 2009 through 2015 on September 18.
