These systems produce        indicators known as diagnostic trouble codes (DTC) internally, usually indicating        something out of the ordinary by illuminating the "check engine"/malfunction        indicator light (MIL) on the dashboard of your car. In the 1990s these systems,        codes and the hardware connectors used to access them were standardized        in North America as OBD (onboard diagnostics) and later OBD-II. Europe uses        the equivalent EOBD, but Volkswagen and Audi vehicles also use another diagnostic        standard system, VAG. Unofficially this acronym can be taken to stand for        "Volkswagen Audi Group."
