Some of the information in this manual applies only to cars of a particular model year or range of years. For example, ?1994 m.y.? refers to the 1994 model year. The model year does not necessarily match the calendar year in which the car was manufactured or sold. To be sure of the model year of a particular car, check the vehicle identification number (VIN) on the car. Technical changes made in production within a model year are identified in this manual by listing the VIN for the first car produced with this change.

The VIN is a unique sequence of 17 characters assigned by Volkswagen to identify each individual car. WVWDB4502NK005678 is an example. Each of the 17 letters and numbers indicates certain facts about the car and its manufacture. VINs used to distinguish information in this manual may refer only to the last eleven digits?the characters 502NK005678 in the example above.

Your Volkswagen's VIN can be found on a plate mounted on the top of the instrument panel, on the driver's side where the number can be seen through the windshield. The 10th character is the model year code. The letters ?I?, ?O?, ?Q? and ?U? are not used for model year designation, for example, ?L? for 1990 m.y., ?M? for 1991 m.y., ?N? for 1992, ?P? for 1993 m.y., etc. This manual covers Volkswagen Corrados for the model years 1990 through 1994.
