Refrigerant Circuit Components
Special tools and workshop equipment required
- Torque Wrench V.A.G 1331
- Hose clamps up to 40 mm diameter 3093
- drip tray for shop crane VAS 6208
- A/C service station VAS 6007A or succeeding model.
Refrigerant must be extracted before hand using VAS 6007A.
The previously used service stations can still be used.
To prevent the ingress of dampness all components of the refrigerant circuit which have been opened must be sealed with suitable plugs.
The color coding of O-rings for the R134a refrigerant circuits has been discontinued. Colored and black O-rings are used.
Under certain conditions, the reservoir and the dryer/dryer bag does not need to be replaced each time the refrigerant circuit is opened. Refer to NOT REPLACING RESERVOIR/FLUID RESERVOIR OR DRYER BAG/CARTRIDGE, CONDITIONS .
Information for repairing vehicles with air conditioning and working with refrigerant, refer to A/C SYSTEM, REPAIR INFORMATION .
Note the following on a vehicle with a Start/Stop System. Refer to START/STOP SYSTEM .
There is a danger of ice-up.
Refrigerant leaks out if refrigerant circuit is not discharged.
Refrigerant must be extracted before opening refrigerant circuit. If refrigerant circuit is not opened within 10 minutes of extraction, pressure may form in refrigerant circuit due to evaporation. Extract refrigerant once more.
