Refrigerant Circuit Pressure Sensor -

G805- , Removing and Installing

Special tools and workshop equipment required
♦ Torque Wrench 1331 5-50Nm - VAG1331-
♦ Commercially Available 12-edge 1/2" Socket Long, 24 Open‐

ing

Removing
– When working on the refrigerant circuit, note the information.

Refer to

⇒ “4.1 Refrigerant Circuit, Specialized Repairs”, page 6

 .

WARNING

Danger due to refrigerant coming out under pressure.
Danger of frost bite to skin and other parts of the body.

• If refrigerant drips out of the refrigerant pipe for longer than

1 second when loosening the Refrigerant Circuit Pressure

Sensor - G805- , then tighten the Refrigerant Circuit Pres‐

sure Sensor - G805- again. The check valve inside the

refrigerant pipe is faulty and must be replaced. 

• Extract the refrigerant and immediately open the refriger‐

ant circuit after that.

• If the refrigerant was extracted more than 10 minutes in

the past and the refrigerant circuit was not opened, extract

the refrigerant again. Pressure in the refrigerant circuit is

caused by evaporation.

WARNING

Danger due to refrigerant coming out under pressure.

• Refrigerant will leak out if improper work is performed

when removing and installing.

Connection damage can be caused.

– Disconnect the connector -2-.
– Counterhold the refrigerant line with a suitable tool.
– Remove the pressure sensor -1- with a Commercially Availa‐

ble 12-Edge 1/2" Socket Long, 24mm .

Installing
Install in reverse order of removal.
Tightening Specifications
♦ Refer to Refrigerant Circuit Pressure Sensor - G805-

-item 19- 

⇒ Item 19 (page 34)

2.4

Expansion Valve, Removing and Instal‐

ling

Special tools and workshop equipment required
♦ Torque Wrench 1331 5-50Nm - VAG1331-
♦ A/C Service Station - VAS6007A- or succeeding model
♦ Engine Bung Set - VAS6122-
Functions
♦ The expansion valve atomizes the streaming refrigerant and

controls the flow quantity so that the vapor is gaseous only at

the evaporator outlet, depending on the heat transmission.

Removing
– When working on the refrigerant circuit, note the information.

Refer to

⇒ “4.1 Refrigerant Circuit, Specialized Repairs”, page 6

 .

Note

♦

Refrigerant must be extracted beforehand using, for example,

the A/C Service Station - VAS6007A- .

♦

The previously used service stations can still be used see

equipment catalog.

♦

To prevent the ingress of dampness all components of the re‐

frigerant circuit which have been opened must be sealed with

suitable plugs.

♦

On some vehicles, connecting pipe from charge air cooler

should be removed. Refer to ⇒  Engine Mechanical, Fuel In‐

jection and Ignition; Rep. Gr.  21 ; Charge Air System; Over‐

view - Charge Air System .

Vehicles with a TDI Engine
– Press the release buttons on the hose -1- for the crankcase

ventilation and remove the hose from the cylinder head cover.

– Free up the vacuum hoses at the air guide pipe -arrows-.
– Loosen the hose clamp -3-.
– Pivot the air guide pipe with the connection rearward and re‐

move from the turbocharger.

All Vehicles
– Remove the sheet metal nuts -1 and 3-.
– Fold the heat shield -2- as far forward as possible -arrow-.

WARNING

Danger due to refrigerant coming out under pressure.
Danger of frost bite to skin and other parts of the body.

• Extract the refrigerant and immediately open the refriger‐

ant circuit after that.

• If the refrigerant was extracted more than 10 minutes in

the past and the refrigerant circuit was not opened, extract

the refrigerant again. Pressure in the refrigerant circuit is

caused by evaporation.

– Extract refrigerant.

– Remove the bolt -1-.
– Disconnect the refrigerant line -2- with the inner heat exchang‐

er from the expansion valve.

– Remove the bolts -1 and 3-.
– Remove the expansion valve -4- from the heat shield insula‐

tion -2-.

– Seal the open lines and connections with clean plugs from the

Engine Bung Set - VAS6122- .

Installing
Install in reverse order of removal. Note the following:
– Replace the seals, version. Refer to the Parts Catalog.
– Replace the seals -1 and 4- on the connecting tubes

-2 and 3- to the evaporator.

– Press in the refrigerant pipe -2- by hand on the expansion

valve.

– Install the bolt -1- by hand and the tighten to the specified

tightening specification.
