Volkswagen Polo Service & Repair Manual: General Information
| All components of the refrigerant circuit submitted for
quality observation are always to be sealed (use original
sealing caps of original part). |
| To date, the original parts (compressor, reservoir,
receiver/dryer, evaporator and condenser) have been filled with
nitrogen gas. This charging stops gradually or the charging
pressure is so low that gas does not escape noticeably when
opening. |
| On vehicles installed with a compressor with no A/C clutch,
the engine is only to be started following complete assembly of
the refrigerant circuit (compressor always in operation as
well). Refer to
→ Chapter „Refrigerant Circuit, General Precautions“. |
| So that the compressor with A/C Compressor Regulator Valve
-N280- (without A/C clutch) is not damaged when the refrigerant
circuit is empty, it is equipped with a secured oil supply. This
means that approximately 40 to 50 cm3
of refrigerant oil remains in the A/C compressor. Refer to
→ Chapter „Refrigerant Circuit, General Precautions“. |
 Note
| As original parts are sometimes stored for lengthy periods
and at different locations within the spare parts organization,
it is entirely possible that gas will escape from some parts and
not from others on initial opening (even in the case of
identical original part numbers). Sealing caps at original part
connections are therefore to be removed carefully and the
nitrogen gas allowed to escape slowly. |
| The refrigerant circuit is equipped either with a restrictor
and accumulator or with an expansion valve and receiver/dryer. |
| Seal open connections and pipes (to prevent absorption of
moisture). |
| Always replace the restrictor. |
| The reservoir/receiver/dryer or dryer bag/cartridge should
not be replaced under the following conditions. |
| After an accident when there is no damage on the
reservoir/receiver/dryer. |
| The repair was done quickly (not beyond the normal repair
time) and no moisture has entered. The vehicle is not older than
5 years. |
| The reservoir/receiver/dryer or dryer cartridge should be
replaced under the following conditions. |
| The refrigerant circuit was opened and the vehicle is older
than 5 years. |
| The refrigerant circuit has been opened for an indefinite
period of time (slow leak). |
| The repair exceeded the normal repair time and moisture has
entered. |
| Always replace the receiver/dryer or dryer cartridge after
flushing with compressed air, nitrogen or refrigerant R134a.
Leave original parts in their packaging as long as possible to
minimize the amount of moisture they absorb. |
| The A/C compressor has locked up. |
| The reservoir/receiver/dryer is damaged (accident). |

Tires, Reinforced, Extra Load
Some time ago, the designation “Reinforced” was replaced
with the designation “Extra Load” by some tire manufacturers. In
countries outside Europe, this designation has been conventional
for some time. There are no technical differences.
