no instrument cluster lights

[Joan Kotjarapoglus <jkot+@pitt.edu>]

Some time ago, I asked for help on an intermittent problem with my
Instrument cluster lignts -- sometime they would all go out including
those on the temperature control panel. Suggestions included to check the 
turn signal - head light - etc control, the dimmer control, ground wire
on the instrument cluster, glove box light and license plate light. I
had tried all except for the bad ground and the problem kept getting
worse until they did not work most all the time.  This trip I told my
mechanic (Jeff at Maroney's in Scottdale Pennsylvania -- great used
parts source for audi (800 -245-7278) to pull the
instrument 
cluster and check the ground.  In checking the wiring diagram he noted 
a relay call instrument cluster booster relay (VDO audi part
number is 447-919-080) supposedly located behind
the radio.  He found it above the rear of the glove box behind a small
panel and sure enought it was bad.  He replaced it and  the dash lights
now work ever time.  I hope this helps someone elses hunt for a solution
 to this problem.  ......I do need some input on replacing a standard seat 
with a power seat on my daughter's car.  Apparently there are different
tracks.  I am going to post an inquirey as a separate e-mail and hope
some suggestions are forthcoming.  Thank again to all of you for your
great suggestion on the instrument cluster problem.  Georg K
