A report from The New York Timesstated Volkswagen was cited by the Environmental Protection Agency for cheating on emissions tests.
The Environmental Protection Agency issued the company a notice of violation and accused the company of breaking the law by installing software called a “defeat device” in 4-cylinder Volkswagen and Audi vehicles from model years 2009-15.
The device is programmed to detect when the car is undergoing official emissions testing, and to only turn on full emissions control systems and reducing Nitrogen Oxide production during that testing.
Those controls are turned off during normal driving situations, when the vehicles pollute far more heavily than reported by the manufacturer, the E.P.A. said.
The defeat device is installed in about 482, 000 Volkswagen vehicles to be recalled due to the cheat.
