Audi Q7: A/C System Repair Information

Audi Q7 (4M) 2016-2024 Workshop Manual / Heating, Ventilation & Air Conditioning / Refrigerant R134a Servicing / Refrigerant Circuit / A/C System Repair Information

  • Air conditioning systems designed for refrigerant R12 are only to be filled with refrigerant R134a if certain requirements are fulfilled. Refer to → Chapter "Refrigerant Circuit, Converting R12 to R134a and Servicing" and Repair manual: Air Conditioner with R12 Parts 2 and 3. This repair manual is only available in hard copy.
  • The refrigerant oils specifically developed for R134a and R12 refrigerant circuits are never to be mixed.
  • Service stations which come in contact with the refrigerant are only to be used for the intended refrigerant.
  • Components of R134a refrigerant circuits can be identified by their markings, green labels or design (such as different threads) to prevent interchanging with components designed for refrigerant R12.
  • A label indicating the refrigerant used is provided in the engine compartment on the lock carrier or in the plenum chamber.
  • Different refrigerants are never to be mixed.

  Note

When working on the refrigerant circuit, always heed the information given in the sections on "Safety measures". Refer to → Chapter "A/C System and Refrigerant R134a Safety Precautions" and "Basic rules for working on refrigerant circuit" → Chapter "Refrigerant Circuit, General Precautions".
