Flushing the air conditioning system

NOTE
The "Flushing" menu is used to flush the vehicle air conditioning
system with fresh refrigerant. Flushing is especially suitable for
replacing old compressor oil or removing most metallic residue from the
system.
Before flushing, the refrigerant must first be extracted from the air con-
ditioning system. Afterwards, the system components which cannot be
flushed must be disconnected from the refrigerant circuit (for example,
the compressor or filter). After that, the components to be flushed are
connected to the service ports of the AirConServiceCenter using
special adapters to form a flushing circuit.

conditioning system and open them.
