Renewing refrigerant circuit components
  Note
t  The refrigerant must be extracted beforehand, e.g. with the air conditioning service station -VAS 6007A-.
t  The previously used service stations can still be used ⇒ Volkswagen Workshop Equipment catalogue.
t  Safety measures when working on an evacuated refrigerant circuit → Chapter.
t  Only the components marked with an * can be renewed without opening and evacuating the refrigerant circuit.
t  To prevent the ingress of moisture, all components of the refrigerant circuit which have been opened must be sealed with suitable plugs.
t  The colour coding of O-rings for R134a refrigerant circuits has been discontinued. Coloured and black O-rings are used.
t  Moisten threaded connections of refrigerant circuit with polyethylene glycol (PEG) VW part number 294440 before installation.
t  Under certain conditions, it is no longer necessary to renew the receiver each time the refrigerant circuit is opened → Rep. Gr.00Technical information “Air conditioning systems - with refrigerant R134a VW” Renewing parts.
