The EPA and the California Air Resources Board said yesterday the German automaker acknowledged the software is on about 85,000 Volkswagen, Audi and Porsche vehicles with 3-litre engines going back to the 2009 model year.

Earlier this month the agencies accused VW of installing the so-called 'defeat device' software on about 10,000 cars from the 2014 through 2016 model years, in violation of the Clean Air Act.
    
The statement says the agencies will investigate and take appropriate action on the software, which the regulators claim allowed the six-cylinder diesels to emit fewer pollutants during tests than in real-world driving.
    
The latest allegation means that more Volkswagen, Audi and Porsche owners could face recalls of their cars to fix the software, and VW could face steeper fines and more intense scrutiny from US regulators and lawmakers.
