My oil pressure metter is showing me that oil pressure is slightly more than 2bar. In books, and in some places in internet, i readed that pressure have to be ~4.5-6bar. All the masters i talked about such a pressure told me that that is OK, and they never seen higher pressure that 2bar on other cars with this engine!
My engine is fine, working quitly, compression rate is ok! So i don't believe that it is worn out! I use Liqui Molly 10W40 semi synthetic oil.

So, how high it have to be? And do I have to vorry about it?

Only way to check is with a direct pressure reading gauge! ;O)

I now checked pressure using external, calibrated pressure metter - 3bar on idle speed, and ~0.1 bar more on 2k RPM... so, any way too low And master told me that he never seen so high oil pressure on other audis(with different engines), so all have to be ok...

Pressure should as a function of oil viscosity/outside temperature and engine temperature.
Normally pressure should read approx 5 bar at start-up and 2 - 3 bar at warm engine (90 deg C).

with hot engine acording to repair manual pressure is suposed to be beetwen 2-4 bar at 2000rpm-s

Thank's all about your reply Now i'm relaxed - i know that all is ok
