Volkswagen Touran Service Manual: Refrigerant Circuit Pipes and Hoses

  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 mixture of refrigerant oil and refrigerant r134a corrodes certain metals (e.g. copper) and alloys and dissolves some hose materials. Therefore use original replacement parts only.
Pipes and hoses are joined by threaded connections or special plug connectors.
  Note
Observe specified torque for threaded connections, use appropriate release tools for plug connectors.
