Distribution Of The Oil Quantity In The Refrigerant Circuit
WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
Information
- Oil removed by suction must be returned to the system!
- Refrigerant oil removed from a previously run air-conditioning system may no longer be used (special-category waste)!
- After the refrigerant has been removed by suction and a component has been replaced, the oil quantity must be determined and topped up by the quantity remaining in the removed component!
When individual components listed in the following table are replaced, the measured oil quantity removed by suction from the refrigerant circuit and the quantity in the component must be returned to the refrigerant circuit.
In order to use a new compressor in a refrigerant circuit that is already functional, the oil quantity for the new compressor must first be reduced by max. 60 cm3 . The compressor oil quantity is 140 cm3 in the scope of delivery for a new compressor.
