Volkswagen Golf Service & Repair Manual: Refrigerant circuit components

  Caution
Non-authorised tools or materials (e.g. leak inhibitor additive) may cause damage or adversely influence the system.
Only tools and materials approved by the manufacturer may be used.
The use of non-approved tools or materials will render the warranty void.
All components of the refrigerant circuit that were submitted for quality monitoring must always be sealed (use the original sealing caps from the genuine part).
Renew damaged or leaky components of the refrigerant circuit → Chapter.
The genuine parts (air conditioner compressor, reservoir, receiver, evaporator and condenser) are charged with nitrogen before shipment. This filling is being gradually discontinued. Therefore, when the sealing plugs are unscrewed from the genuine part little or no pressure equalisation is noticeable.
