Someone has already pointed out that it's likely that the ground
connection is bad. As they said, follow the wires from the lamp until
you find where it makes contact with the chassis ground.
I have yet to own an Audi (hoping to change that in a week!), but
there's another possibility. The trunk switch could be switching
either the +12 or the ground. IF for some reason, Audi uses
the "supply +12 constantly and switch the ground" method, then
the problem could also be a worn or broken switch. Find your
trunk lid switch and start playing with it. If you're *sure*
that it switches *ground*, then try pulling the wire to the
lamp off of the switch and touching it to a metal ground point.
If the lamp lights, replace the switch.
