AC Pressure Switch Testing

[chamaur]

Thanks ard for the quick reply. I did hook up my BMW scan/reader tool and there were no errors on the system.

I then connected a can of freon to the system and the gauge shot right up to 100 psi on the low side, but the clutch on the compressor still wouldn't engage. I did not add any additional freon to the system.

I will take some time and go through the www.newtis.info site and see what I can find.
