CA Regulators Find 1,600 More Cars Cheating Emissions Tests

Nov 3, 2015

California regulators expect to recall as many as 1,600 more Volkswagen diesel vehicles for defeating emissions tests.

The U.S. Environmental Protection Agency and the state Air Resources Board sent letters to Porsche, Audi, and Volkswagen Monday.

All are subsidiaries of Volkswagen Group, which has already admitted to installing emissions-evading software in almost a half-million of its smaller diesel engines.

Dave Clegern of the Air Resources Board says this time, it’s larger luxury and crossover vehicles, using different software.

It preheats the catalytic converter, basically, so that the car on the test cycle is emitting the kinds of emission sit would emit with a warm engine, which is basically when it should be running with the lowest emissions,” Clegern said.

The carmakers have not admitted to installing the software. Nationally, the EPA expects to recall up to 10,000 vehicles.
