Oil pressure guage

["Sean Ford" <sean@nwh.org>]

update on paranoid buyer and pre-purchase inspection: car came through with
flying colors with one exception regarding the spare tire (not important
enought to discuss and will be taken care of). Anyway! While driving to the
Audi mechanic, I watched the oil pressure gauge.. while driving it was
pegged at 5 bar and at idle it would hover around 2 bar. Ok, I'm a goof.
What the hell does this mean? Is this normal? I scanned the owners manual
and could not find a "normal operating range" or anything along those lines
for the oil pressure. Should I only worry if it drops suddenly? Help?
