Volkswagen Golf Mk7 Service & Repair Manual: Bringing air conditioning system into service after charging

Note: if the Volkswagen Golf Mk7 compressor was removed, turn the V-belt pulley or freewheel by hand approximately 10 times before first operation — this prevents fluid hammer damage.

  Note
If the air conditioner compressor was removed, the V-belt pulley /freewheel must be turned by hand approx. 10 times prior to initial operation. This prevents any damage occurring from a fluid hammer in the air conditioner compressor when the air conditioning system is switched on for the first time. If there is oil in the cylinder of the air conditioner compressor, it will be forced out by the rotation.
   
–  Start with engine with air conditioner compressor switched off (if it is the type with a magnetic clutch).
–  Set air conditioner compressor to lowest possible setting; select "ECON" mode or "A/C Off" (if version without magnetic clutch, but with regulating valve).
–  Wait until idling speed has stabilised.
–  Switch air conditioner compressor on and let system run for at least 2 minutes with engine idling.
–  If necessary, check pressures in refrigerant circuit using air conditioner service station.
–  Switch off engine.
–  Turn out handwheel on quick-release coupling adapter.
