Volkswagen Tiguan Service and Repair Manual: Adapter for Assembling Flushing Circuit
- The following table lists the different adapters necessary to connect
the service station to the refrigerant circuit, to flush and to bypass the
removed receiver/dryer or reservoir and expansion valve (depending on the
vehicle).
- Using a charge hose with 5/8 -18 UNF connections (short version, for
example Refrigerant Circuits Adapter Set 1 - Hose 31 -VAS6338/31-), connect
the two adapters (contained in Refrigerant Circuits Adapter Set 1
-VAS6338/1-) which have been installed for the removed reservoir or
receiver/dryer.
- If a flushed refrigerant circuit is not reassembled immediately after
flushing, adapters remain at connections and seal the connections at the
adapters using Refrigerant Circuits Adapter Set 1 - Adapter 30 -VAS6338/30-
(from Refrigerant Circuits Adapter Set 1 -VAS6338/1-).
- Depending on the version of the A/C compressor and on the time period of
production, various connecting and sealing technologies can be found on the
refrigerant circuit. Refer to Heating, Ventilation and Air Conditioning.

The Passat 2015 and Passat Wagon 2015 with a Biturbo engine are not flushed.
The amount of work to remove the expansion valve is too excessive. If there is
A/C compressor damage, check whether there are shavings in the condenser and
whether there are shavings on the condenser output. If there are shavings on the
input and not on the output, then only the condenser and A/C Compressor need to
be replaced.

Valve -N542- with two Shut-Off Valves -VAS 6338/42-. Refer to the
information found here.
- The restrictor in the refrigerant line to the High-Voltage
Battery Heat Exchanger is removed and drilled out. Refer to the
notes below
|
Note
The refrigerant circuit is flushed in 2 phases for the Golf Hybrid 2014. In
the first flushing cycle the adapter for the heater and a/c unit refrigerant
cut-off valve - N541 is opened and the adapter for the high voltage battery
heater core refrigerant cut-off valve - N542 is closed. From this, the
refrigerant circuit with the evaporator in the Heater and A/C Unit is flushed.
In the second flushing cycle the adapter for the heater and a/c unit refrigerant
cut-off valve - N541 is closed and the adapter for the high voltage battery
heater core refrigerant cut-off valve - N542 is open. From this, the refrigerant
circuit with the evaporator in the high voltage battery heat exchanger is
flushed. Refer to Heating, Ventilation and Air Conditioning, Repair group 87,
System Overview - Refrigerant Circuit (vehicle-specific repair manual).
Note
- This illustration shows a refrigerant line -A-
with a permanently installed restrictor -B-
(without a strainer) This refrigerant line is to be drilled open to 5.0 mm
using a suitable drill to flush the refrigerant circuit (an inserted
restrictor is to be removed) and is to be cleaned in the flushing circuit
before installing. The drilled refrigerant line is replaced after flushing.
Refer to the Parts Catalog.
- The diameter of the illustrated restrictor bore
-B- is approximately 0.7 mm. Depending on the version of the
refrigerant line this constriction is either installed fixed in the
refrigerant line or only inserted. For the inserted version a strainer for
flowing deposits may be installed, which can be blocked by the variable
orifice.
