Audi Workshop Service and Repair Manuals

The air conditioner refrigerant circuit may only be emptied and opened () or if it is necessary to renew parts of the air conditioner refrigerant circuit.

The air conditioner refrigerant circuit must remain closed during all other normal repair operations.

Repair work which may be performed on the heating and air conditioner without opening the refrigerant circuit are described in this workshop manual => Page 87-8 onwards.

Note:

The connections for the switches described in the workshop manual are fitted with a valve which closes automatically when the switches are unscrewed. These switches may therefore be renewed in any VW/Audi workshop without draining the refrigerant circuit.

Repair work on the air conditioner that requires the refrigerant circuit to be drained and hence cannot be performed in every VW/Audi workshop, is described => from Page 87-130 (vehicles should be sent to a VW/Audi air conditioner service centre for the refrigerant circuit to be drained).
