With Expansion Valve, Receiver/Dryer And Electrically-Driven A/C Compressor
WARNING: This page is about a different car, the 2017 Volkswagen Touareg, 2016 Volkswagen Touareg, and 2015 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The electrically-driven A/C compressor does not have an A/C Compressor Regulator Valve -N280-. The A/C compressor RPM does the regulating. The A/C compressor contains the control electronics and a G-charger, which moves the refrigerant.
