LOS ANGELES: California air quality regulators are demanding fixes for up to 16,000 additional Volkswagen, Audi and Porsche diesels as the Volkswagen Group emissions scandal widens.
The California Air Resources Board made the demands Wednesday after state and federal regulators disclosed last week that Volkswagen installed software to cheat emissions tests on more diesels than initially thought.
Volkswagen told the U.S. Environmental Protection Agency and the California Air Resources Board it had installed undisclosed emissions control devices on about 85,000 Volkswagen, Audi and Porsche vehicles with 3-liter, six-cylinder engines going back to the 2009 model year.
Earlier this month, regulators accused VW of installing the so-called "defeat device" software on about 10,000 cars from the 2014 through 2016 model years.
The carmakers have 45 business days to present a recall plan.
