Volkswagen Touran Service Manual: A/C without Magnetic Clutch with Torsion-Elastic Clutch

  Caution
Non-approved tools or materials such as leak sealing additives can cause damage or malfunctions in the system.
Only use tools and materials approved by the manufacturer.
The warranty is voided if non-approved tools or materials are used.
All components of the refrigerant circuit submitted for quality observation are always to be sealed (use original sealing caps of original part).
Replace damaged or leaking components of refrigerant circuit. Refer to → Chapter "Components, Replacing".
To date, the original parts (compressor, reservoir, receiver/dryer, evaporator and condenser) have been filled with nitrogen gas. This charge is being gradually discontinued. There is little or no pressure equalization when removing the sealing plugs from the original part.
   
The A/C compressor is driven directly by the power steering vane pump.
On the A/C compressor driveshaft, there is an overload protection that shears off when the compressor is blocked so that the power steering vane pump remains functional.
The A/C compressor extracts the refrigerant gas from the evaporator, compresses it and relays it to the condenser.
  Note
The A/C compressor contains refrigerant oil, which can be mixed with refrigerant R134a under any temperature.
The type plate lists the type of refrigerant required for the A/C compressor. A regulator valve regulates pressure within the specified range (control characteristics) on the low pressure side.
On this A/C compressor, the control valve is activated from outside.
The engine should only be started if the refrigerant circuit is completely assembled. Refer to → Chapter "Refrigerant Circuit, General Precautions".
The A/C compressor is equipped with a protected oil supply, this prevents A/C compressor damage in the event that the system is empty. This means that approximately 40 to 50 cm3 of refrigerant oil remains in the A/C compressor.
