2010 2.0 TDI AC Questions

Hey all, my air conditioning is not engaging on my 2010 Jetta. There are no leaks in the system as I had my gauges on it. I’m in search of a diagram with labels for the whole AC system. I want to test the high and low limits, and see if I can get the compressor to come on. Any help is appreciated

Also, does anyone know how much refrigerant this system takes ? Thanks

*sigh*...

Search "RCV", and get a scan tool that speaks VAG.
