Yeah, hence the $500 to replace pretty much every wire
under the dash... It was fairly lousy advice from the local
VW/Audi repair place. To their credit, it would've been
helpful as a diagnostic aide in the driveway, as one
wouldn't have to keep replacing the fuse to see if it's
fixed, but I definitely wouldn't drive around like that.

And BTW, I took it to a different mechanic to get it fixed.
Fool me once, shame on you...

I guess another question I had was since the fuel pump
circuit is so prone to malfunction on these older Audis,
has anyone come across a way to switch it to something that
works better?

Seems to me after 20 years of little wiring harness demons
someone would've come up with the magic cure.
