I've been doing some research trying to find out what "normal" values are for these.
Somebody on ClubGTI suggested the following oil pressures for the 1.8T engine.
Cold Idle (approx 1400rpm): - 87.02 - 94.30psi / 6 - 6.5bar
Hot Idle (approx 720-760rpm): - 20.31psi / 1.4bar
Approx 1000rpm: - 26.11 - 29.01psi / 1.8 - 2.0bar
Approx 3000 - 4000rpm: - 58.02psi / 4bar
Approx 6000-6500rpm: - 87.02psi / 6bar
However I can't find what is classed as normal oil temperature. The measuring location in question would be the sump and I was thinking somewhere in the region between 90-120C?
