Volkswagen Polo Service & Repair Manual: Refrigerant in A/C Service station Container, Filling
Caution
| If it is suspected that chemicals were added to the
refrigerant circuit to seal leaks, do not 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 failure of the A/C system and the A/C
service station. |
| Inform that customer that there are substances in
the A/C system that are no approved by Volkswagen. This
A/C system cannot be drained or serviced in the
workshop. |
|
 Note
| The chemical materials (stop leak additive) for sealing
leaks in the refrigerant circuit offered on the market are not
approved by VW Audi AG. There are no permanent- ,validity or
material compatibility tests. Therefore damage or malfunctions
in the A/C system or the A/C Service Station cannot be excluded. |
| The stop leak additives offered on the open market have
different physical and chemical properties, which can impair the
function of the A/C system and the A/C Service Station and can
even shut down the system completely. |
| 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. |
| The work procedure is always to be performed as described in
the operating instructions for the A/C service station. |
| A certain quantity of refrigerant is specified as charge for
each air conditioning system. To ensure that the correct amount
of refrigerant is added and the cooling output is not reduced,
the charging cylinder stands on a scale indicating the weight. |
