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. |
