Following the Transport and Environment's study that ﻿we reported December last year , which claimed that ﻿90% of new diesel cars exceed the Environmental Protection Agency pollution limits as manufacturers had been making alterations to cars in order to pass emissions tests; EU ( EPA ) has accused Volkswagen (VW) of installing software on cars sold in the California that allowed them to cheat on pollution measurement tests. "Only then did VW admit it had designed and installed a defeat device in these vehicles in the form of a sophisticated software algorithm that detected when a vehicle was undergoing emissions testing," the EPA said. According to the the Environmental Protection Agency , software algorithms fitted to the VW cars can detect when the car's emissions are being tested, by turning on pollution controls that cut nitrogen oxides from being pumped out of the exhaust. Volkswagen faces an $ 18bn penalty over the device, which has been cheating the clean-air standards during official emissions testing.
