[200q20v] Engine problem on the 20v TQ

[Anti Heinsoo]

Actually I did find a leak.. it was in that typical location at the top of
the radiator - the
plastic end which has the hose coming from the engine connected to it had
broken off
and the previous owner had attached it back to the tiny bit left. We got the
idea of
ordering a conical metal piece from a handyman nearby to be screwed inside
the
radiator to restore it.. had exactly the same problem with my '85 200t, too
bad Audi
hadn't done anything about it in the 5 years in between.. Anyway, seems that
fortunately
the engine and coolant problems are unrelated, but thanks for the suggestion
:).

About the resistance of the injectors... how do I do that? :).. sorry, but
I'm quite a newbie
in the DIY thing.. :). I tried the ECU test for injectors, they all clicked
OK, we also measured
the pressure in the cylinders which was equal in all 5.
