Volkswagen Touran Service Manual: Refrigerant Circuit, Flushing

  Note
For vehicles in which no adapters fit on to the refrigerant pipes, for example, a blower pistol with rubber mouthpiece is to be used to blow through individual components. Special care must be taken not to damage the connections (crushing or scratching).
Evaporator is to be flushed via the connection for low-pressure pipe (large diameter) after removing expansion valve or removing restrictor.
Always flush components in direction opposite of refrigerant flow direction.
Check expansion valve and replace if dirty or corroded.
If there are dark, sticky deposits in the components that cannot be removed with compressed air, replace these components.
Thin, light grey deposits on the insides of refrigerant pipes do not impair the function of the components.
After flushing, always replace receiver/dryer or reservoir and restrictor. Replace dryer cartridge or dryer on condensers with attached dryer.
