Fuse blowing UBERWGN

UBERWGN (my 95.5 S6 Avant) continues to blow one or two fuses
intermittently.  Neither I nor the dealer can make it happen when we
want it to happen.  It seems to happen only after a period of idling,
or usage of the interior lights/radio with the engine off.  Happens
about once a week.  The fuse that powers the interior lights, gas gage,
etc. is the common one that blows.  You can replace the fuse
immediately, and it will then refuse to blow again.

So we're trying to figure out how to isolate the problem.  One idea is
to wire some in-line fuses in front of each component on this circuit,
and see which one blows.  Another is to just disconnect non-critical
components until the problem goes away.  Of course, we could just go
replacing components too, but that's too expensive.

Anybody else got any good ideas about how to isolate a transient
problem like this?
