I believe that the LED trick works on Coupes up to the magical March '90
production date, when they changed it to require you to buy the special
Audi box.  The fuel pump fuse was used only on California spec Coupes,
if I recall correctly (and I usually don't).  Now that I think about it, I'm not
sure if the Cali cars used a fuel pump fuse, but I'm pretty sure their codes
are displayed on the check engine light.
Of course, all of this probably has _very little_ to do with Mike's '91 turbo
sedan, which I know _nothing_ about, except that I wish I owned one.
(sorry Mike)
