WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2009 Audi S4, 2009 Audi A4, 2008 Audi S4, 2008 Audi RS 4, and 2008 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- For a description of the various instrument panel vents, refer to → Instrument panel vents and air guides .
- The following illustrations show a instrument panel of the type installed in a Saloon or Avant up to VIN 399999 in Model Year 2005. The shape of the instrument panel on a Cabrio or for a Saloon or Avant as of VIN 400000 in Model Year 2005 (for Saloon and Avant; gradual introduction for the Cabrio in week 46/04 without prior specification of any particular VIN
) differs slightly from these illustrations
