Relay logic is alive and well in your Audi.

To get the fogs to work without the low beams being on, all
I did was bypass the fog light relay which is engaged when the low beams
(but not the high beams) are on.

Here are two pictures of my workaround:

It is also relatively easy to make the rear fog work independently of
the front fog.  In that case it was a matter of putting a thin piece of
insulating plastic between two contacts inside the rear fog switch.  I
can dig up the relevant info on the rear fog if anyone is interested.
