The all-in-one switch is only on the 98 and later A6.  All previous Audis
as well as the current A4 and A8 have separate fog light switches,
if so equipped.

By the way, US cars' fog lights are controlled via a relay such that they
don't come on until your headlights are turned on to low beam.  However,
there is a modification that can be done to override this and allow
them to be turned on without turning on the main headlights.  Check
audiworld.com for details.
