speaking of intermittent problems...

[gordy.schesel]

I have had this problem recently also.  Started with a burned out
brake lamp.  Replaced lamp with a spare I had on hand, whoever
the alarm and auto check indicator, a bulb with an 'X' through it
continued on an intermittent basis.  I then purchased a matched
set from Audi parts, still no improvement.  The alarm sounding is
annoying and there does not seem to be a pattern except I find it
most often after driving a few minutes, then the alarm stops
sounding on long drives of 20 miles or more, but the auto check
indicator stays lit.  

I have checked the Bentley for a fuse to silence the alarm, there
isn't one for the auto check. I believe there is a real lamp
control unit in the trunk; is it possible that that component is
somehow faulty?

Is there an auto check control unit under the hood?
Coincidently, along with a burned out brake lamp, this problem
started when I washed down my engine compartment in the driveway
with the garden hose.  Did I short something out?  The problem is
with my 100 quattro.
