An exhaust gas analysis is to be performed, in a manner that is largely automatic, on motor vehicles having an on-board engine control and diagnostic system (OBD 2) and equipped with a diagnostic interface (3). To this end, control commands (15) are generated, preferably in an exhaust gas tester (12), and are transmitted via the diagnostic interface (3) to the engine control and diagnostic system (2). The engine control and diagnostic system (2), in accordance with the control commands (15), adjusts the operating states of the motor vehicle (1) that are prescribed for the exhaust gas analysis.
