Volkswagen Golf Service & Repair Manual: Reservoir

The reservoir collects the vaporised and gaseous mixture coming from the evaporator to ensure the air conditioner compressor receives only gaseous refrigerant. Gaseous refrigerant is formed from the vapour.
Refrigerant oil flowing in the circuit does not remain in the reservoir, as an oil extraction hole has been provided.
Moisture which has entered the refrigerant circuit during repairs will be collected by a filter (dessicant bag) in the reservoir.
Gaseous refrigerant with oil is drawn in by the air conditioner compressor.
  Note
Renew the reservoir if the refrigerant circuit has stood open for any length of time (more than the normal repair time) and moisture has entered the system, or if it is required because of a specific complaint → Chapter.
Do not remove sealing plugs -A- and -B- until just before installation.
The dessicant bag in an unsealed reservoir will become saturated with moisture within a short time and is then unusable.
When installing, observe arrow indicating direction of flow, if applicable.
