My '89 100Q reads about 5 bar at idle when cold. Revving pegs it.
When the oil is warm, it reads about 1.5 bar at idle, revving
moves it to about 4.5 bar.

These are all a little higher with fresh, thicker oil, and a little
lower with old, thinner oil.

My wife's '90 90Q20V reads about the same, maybe a little higher
at idle.

Every kind of car is different about oil pressure. The Firebird's
design has nothing to do with the Audi's design. A friend had a
police-issue New Yorker that read 80-90 pounds (6-7 bar) at idle
when hot.
