Looks like the dimmer switch is built into the combo turn signal wiper switch on the column.
I would unplug that switch and see if the indicator light goes off.
If it does the problem may be inside the combo switch.

When you are talking about "indicators" we could assuming that your are refer about signal lights. This work with "flashers" devices.

For 1996 Audi A4 2.8L SFI 6cyl the Flasher is located in front seating area, driver side, under dash, behind dash lower panel, mounted above driver side of steering column.

About generic fuses, open the driver side door. Remove panel on left side of dash. Fuse box is behind panel:
