– Remove the oil supply line.
Installing:
– Check the oil supply line for leaks.
– Fill the turbocharger with engine oil at the oil supply line con‐

nection.

The Additional Numbered Steps Must Be Followed to Ensure the

Oil Supply Line Is Installed Correctly:
1.

Set the union nuts of the oil supply line onto the connections.

2.

Tighten the union nut on the oil filter bracket hand-tight.

3.

Tighten the union nut on the turbocharger hand-tight.

4.

Tighten the union nuts on the oil filter bracket first and then

tighten the union nuts on the turbocharger.

• Tightening specification -item 6- 

⇒ Item 6 (page 178)

 .

5.

Mount the clamps and tighten the bolt and nut:

• Tightening specification 10 Nm.
The rest of the installation is performed in reverse order of re‐

moval, while doing so pay attention to the following:

Caution

Make sure the connecting pipe decoupling element does not

bend or stretch. Cracks could develop.

Note

The connecting pipe between the exhaust manifold and inter‐

mediate sprocket must be replaced after removal.

– Install the connecting pipe between the exhaust manifold and

intake manifold -item 29- 

⇒ Item 29 (page 273)

 .

– Install the warm air collector plate -item 2-

⇒ Item 2 (page 271)

 .

– Install the intake scoop -item 35- 

⇒ Item 35 (page 273)

 .

– Install the charge air pipe -item 15- 

⇒ Item 15 (page 291)

 .

– Install the intake hose between the Mass Airflow Sensor - G70-

and the intake scoop. Refer to

⇒ “3.14 Overview - Air Filter”, page 335

 .

– Install the air filter housing. Refer to

⇒ “3.14 Overview - Air Filter”, page 335

 .

– Install the engine cover. Refer to

4.4.1

Oil Pressure Switch - F1- , Checking

Special tools and workshop equipment required
♦ Oil Pressure Gauge Kit - VAG1342-
♦ Voltage Tester VAS6839 - VAS6839-
♦ Connector Test Set - VAG1594D-
♦ Wiring diagram. Refer to ⇒ Wiring diagrams, Troubleshooting

& Component locations.

Test Conditions
• The engine oil level is OK, Checking. Refer to

⇒ “1.2 Engine Oil, Checking Level”, page 151

 .

• The engine oil temperature is at least 80 °C (176 °F) (the Ra‐

diator Fan - V7- must start up once).

Test Sequence

Note

Functional check and servicing of the optical and acoustic oil

pressure gauge. Refer to ⇒ Wiring diagrams, Troubleshooting &

Component locations and Voltage Tester VAS6839 - VAS6839-

“Function and Component Selection”.

– Disconnect the connector from the Oil Pressure Switch - F1- .
– Remove the Oil Pressure Switch - F1- -2- and install it in the

Oil Pressure Gauge Kit - VAG1342- .

– Install the Tester in place of the Oil Pressure Switch - F1- into

the bracket.

– Connect the brown wire -1- of the Tester to the ground.
– Connect the Voltage Tester VAS6839 - VAS6839- to Battery

- A- positive (+) terminal and the Oil Pressure Switch - F1-

using adapter cables from the Connector Test Set -

VAG1594D- .

• LED must not turn on.
If the LED turns on:
– Replace the Oil Pressure Switch - F1- :
• Tightening specification -item 7- 

⇒ Item 7 (page 178)

 .

If the LED does not turn on:
– Start the engine and slowly increase the speed:
• LED must light up at 0.55 to 0.85 bar (7.97 to 12.32 psi) pres‐

sure, otherwise replace the Oil Pressure Switch - F1- .

• Tightening specification -item 7- 

⇒ Item 7 (page 178)

& Component locations.

Conditions
• The Oil Pressure Gauge Kit - VAG1342- is connected. Refer

to 

⇒ “4.4.1  Oil Pressure Switch F1 , Checking”, page 184

 , Oil

Pressure Switch - F1- , Checking.

Test Sequence
– Increase the speed further.
• At 2000 RPM and an oil temperature of 80 °C (176 °F), the oil

pressure should be at least 2.0 bar (29 psi).

• At higher engine speeds, the oil pressure must not exceed 7.0

bar (101.52 psi)

If the specified value is not obtained:
– Replace the oil filter bracket if necessary. Refer to

⇒ “4.1 Overview - Oil Filter Bracket and Oil Cooler”,

page 177

 , Overview - Oil Filter Bracket and Oil Cooler

Note

Also, mechanical damage, for example, bearing damage can also

be the cause of too low oil pressure.
