New to Audis...Again

[Doyt W. Echelberger]

I have a 1987 5ktq with the same condition. I can give you a little 
information about what my car is doing, but I don't have the solution yet.

Problem stays away while car is warming up.....maybe 3-4 minutes on a cold 
engine.  Then when it comes on  (as you say) it goes off immediately when I 
back off the accelerator a little bit.

I did find something that partially improved but did not cure the problem.

I found a small loose vacuum line and reconnected it, and the condition 
became less sensitive. So, I suspect that I have a second undiscovered leak 
somewhere.  After fixing the obvious leak, I could egg-shell accelerate 
without triggering the light. But normal use of the accelerator still 
brings on the light.
