Air Conditioning, Cleaning of the Refrigerant Circuit (U.S.Only)
Debris can be dispersed throughout the refrigerant circuit after a/c component damage.
In order to maintain A/C operating efficiency, it is important to flush the refrigerant
circuit after A/C component repairs.
TECHNICAL BACKGROUND
In cases where an air conditioning system component (such as a compressor or other
system component) has failed and debris from the compressor or component is circulated
throughout the refrigerant circuit, the refrigerant circuit must be cleaned of any and
all debris or damage to the replacement components will result.
PRODUCTION SOLUTION
No production change required.

? Use the ROB134APF Air Conditioning Service System with VAS 6337/1A Air
Conditioning System Flushing Device (Figure 1) Used for effective refrigerant
handling and air conditioning circuit flushing after air conditioning component
failure.
? Now air conditioning system refrigerant recovery, evacuation, recharge and
refrigerant circuit cleaning after component failure can be performed with a
single servicing station.

The VAS 6338/1 Adapter Set for Refrigerant Circuits. Along with an additional
adapter (VAS 6338/33 for the front expansion valve bypass for the Touareg) this
kit contains the adapters necessary to complete a thorough flush operation of a
contaminated circuit.
Elsa contains the technical information for each model regarding the necessary
adapter applications and connections of the servicing station for the flush
operation. See Heating, Ventilation & Air Conditioning >> Refrigerant R134AServicing
>> 00 General Technical Data>> Refrigerant Circuit removing
contaminates>> Refrigerant Circuit, Flushing with Refrigerant R134A in Elsa.
All other refrigerant recovery, evacuation and recharge operations are performed
using the usual procedure specified in Elsa. An operations manual will accompany
each servicing station that will describe operation of the unit.
PROCEDURE
Front A/C:
1. If an air conditioning component has been diagnosed as the root cause of the
failure and this component is suspected of releasing debris through the circuit,
continue the diagnosis to determine if this is the case.
2. Turn the power to the servicing station on and begin by recovering the refrigerant
from the system through the normal service fittings.
Tip: During the entire process avoid interrupting the power to the station. The
station's internal memory will keep a log of all operations and can conveniently
be recalled and printed. If the power is interrupted, the station will lose the
memory of the process, and the oil volume recovered, oil volume added, refrigerant
volume recovered, etc. will have to be manually determined.
3. Disconnect the service hoses. The VAS 6338/1 adapters will be used to bypass the
following:
Before flushing the A/C circuit, inspect the Receiver-drier cartridge screen for
any tears and for any desiccant material that may have been released into the A/C
circuit. If the Receiver-drier screen is torn, replace the condenser prior to
starting the flushing procedure.
? Compressor.
? Receiver-drier.
? Expansion Valve/Restrictor (if equipped).
If vehicle is equipped with a restrictor, remove the restrictor and reconnect the
line.
NOTE: For models in which the Receiver-drier is not over flushed as per the
repair manual, the desiccant cartridge must be removed for the flushing
process.

4. Once the appropriate adapters are in place, connect the service station to the
vehicle through the air conditioning compressor hoses. The flushing attachment
ports are labeled on the flusher (Figure 2 and Figure 3).

? This connection strategy allows for a system flush in the opposite direction
of the normal refrigerant flow (Figure 4).

? The flush program will begin with an evacuation of the system and a rate of
rise test. This is necessary to test the integrity of the connections before
the flush cycles begin. If the rate of rise test passes, the program will
proceed into the flush cycles. (Figures 5 - 7). These cycles will occur
automatically in succession.

? The debris is then rinsed from the circuit and contained within the
filtration in the flusher. After the flush program, the system will be
evacuated.
5. After the system is evacuated, remove any adapters that were installed from the
VAS 6338/1.
6. Replace Expansion Valve (if equipped), Receiver-drier and Restrictor (if
equipped).
7. Connect the station in the usual manner through the service fittings and perform
the normal evacuation and refrigerant recharge operations.
8. Print a log of the job and attach to the repair order.
TOUAREG WITH FOUR ZONE CLIMATE CONTROL - REAR A/C
For Touareg with four zone climate control, the flush process will be repeated for the
additional air conditioning unit (rear of vehicle) according to the repair information
in Elsa.

1. Separate the front and rear air conditioning systems for individual rinse
operations.
The VAS 6338/1 contains the necessary adapters to separate the systems for the
individual rinse operations.
