In September of 2015, the EPA issuedVolkswagen (OTCPK:VLKAY)https://seekingalpha.com/symbol/VWAGY a notice of violation of the Clean Air Act of 1963. The EPA accused the Volkswagen Group of intentionally programming diesel engines to activate emissions controls only during emissions testing. Vehicles with this programming passed emission control tests for nitrogen oxide emission but emitted up to 40 times more nitrogen oxides when driven. It was believed that between 2010 and 2015 about 500,000 of the polluting vehicles were sold in the U.S. Volkswagen admitted that about 11 million cars, worldwide, had been programmed to provide false information on emissions.
