Berlin (AFP) – Germany’s embattled Volkswagen on Monday denied claims by US environmental regulators that it had also included “defeat devices” to skirt emissions rules on certain larger diesel engines.

“Volkswagen underlines that no programme has been installed in its V6 3 litre diesel engines” that would “inappropriately modify” the results of anti-pollution tests, a statement said, responding to Environmental Protection Agency claims that various 3.0 litre diesel VW Touareg, Porsche Cayenne and Audis from the 2014-2016 model years had been rigged with software designed to cheat US regulations.
