Service Station

CAUTION:
- If it is suspected that chemicals were added to the refrigerant circuit to seal leaks, do no connect the A/C service station and do not extract the refrigerant.
- Chemicals that seal leaks in the coolant circuit form deposits that affect the function of the A/C system and lead to A/C system failure (and failure of the A/C service station).
- Inform that customer that there are substances in the A/C system that are no approved by VW. This A/C system cannot be drained or serviced in the workshop.


NOTE:
- VW does not approve the use of chemicals to seal leaks in the refrigerant circuit.
- Chemicals used to seal leaks in the refrigerant circuit often react with air and the moisture in it. They cause deposits in the refrigerant circuit (and the A/C service station) and malfunctions in valves and other components that they come in contact with. These deposits cannot be removed completely from the components.
- Chemicals used to seal leaks in the refrigerant circuit usually cannot be detected from outside. The label that should be applied to identify it is often missing. Therefore be careful when working with if you do not know its service history.
- Accessories offer containers used to separate out these chemicals (used to seal leaks in the refrigerant circuit). Because VW does not approve the use of these chemicals, there is no evidence of the effectiveness of these filters.
