I’m sorry to inform you, but according to the EPA your car has been polluting the environment at a level between 10 and 40 times its legal limit. Volkswagen and Audi, who manufacture the majority of diesel vehicles in the United States, have been cheating emissions tests instead of complying with more stringent smog-forming pollution standards.
