Some of the information in this manual applies only to cars of a particular model year or range of years. For example, ?1999 m.y.? refers to the 1999 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 Audi to identify each individual car. WAUCB88DXVA169020 is an example. Each of the 17 letters and numbers indicates certain facts about the car and its manufacture.

The 10th character is the model year code. The letters ?I?, ?O?, ?Q? and ?U? are not used for model year designation, for example, ?X? for 1999 m.y., ?Y? for 2000 m.y., ?1? for 2001 m.y., etc. This manual covers Audi A4 for the model years 1996 through 2001.
