After refilling the A/C system I discovered that the pressure and temperature at the high pressure side was quite high. Does anybody knows what pressure and temperature can be expected with a full running A/C and a outside temperature of 25 degrees Celsius? My other question is what should be approximately the air temperature coming out of the air ducts in the interior when the car is standing still?

At 25 degree C, the center nozzle outlet should be between 8 degrees C and 11 degrees C. This assumes condensor is clean, temperature control switch is set to 'max cold', defrost and footwell lever against the right stops (opened), blower speed on 4, all dashboard outlets open, sun roof, doors and windows closed, engine speed at 2000 rpm, compressor running at least two minutes, and car not in the sunshine.

230-270 psi at 30 C for the high side.
the pressures will be slightly lower at 25C

I hope you will get the right info here Henrik. Just convert the Psi dates and you're informed.
