Please urgent help needed high engine temp!

[vladimir mitic]

I cheked the thermoswitch and it is OK, fan also work fine. I also
changed the termostat (mechanical termo switch) and complete
antifreeze (7 liter). Could it be poor water flow becouse waterpump? I
suspect that becouse no water comes aut of that small hose from top of
the radiator to water container when engine idle. Only when is about
so hot to turn on the fan on, 1 or 2 sec. before water go thru that
hose. Any ideas? I need help becouse that is my only car. How hot your
audis run? In C°? Is there any data from the factory what is normal
working temp?
Thanks.
