With Expansion Valve, Receiver/Dryer And Electrically-Driven A/C Compressor
WARNING: This page is about a different car, the 2014 Volkswagen Touareg, 2013 Volkswagen Touareg, 2012 Volkswagen Touareg, and 2011 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.
