Volkswagen’s diesel emission scandal has widened—yet again—this time ensnaring Porsche.
In an announcement today (Nov. 2), the US Environmental Protection Agency (EPA) alleged that the defeat device installed in more than 11 million Volkswagen diesel vehicles around the world has also been found in some Porsche vehicles. This was the second notice of violation of the Clean Air Act the EPA has sent to Volkswagen.
The only Porsche model named in the latest notice was the 2015 Porsche Cayenne diesel vehicle, an SUV with an estimated dealer price of more than $71,000, according to Edmunds.com.
Former Porsche head Matthias Müller stepped into the CEO role at Volkswagen group in September as part of a management shake up that included the resignation of previous CEO Martin Winterkorn. Müller has not yet commented on the EPA’s latest notice, and the company did not immediately respond to Quartz’s request for comment.
The latest notice of violation also named additional Volkswagen and Audi models. The first notice only addressed 2.0 liter diesel engines, while this involved 3.0 liter engines.
The EPA has not yet ordered a recall.
The automaker is already in the midst of a 8.5 million vehicle recall—one of the largest ever—as a result of the scandal.
Updated, Nov. 3 at 9:30 am: Volkswagen said in a statement on Monday (Nov. 2) that it “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.” The company added that ”it will cooperate fully with the EPA clarify this matter in its entirety.”
