Oil Pressure Sender: Testing and Inspection

Oil Pressure and Oil Pressure Switch, Checking

Special tools, testers and auxiliary items required

• Oil pressure gauge (V.A.G 1342)

• Adapter (V.A.G 1342/14)

• Voltage tester (V.A.G 1527B)

• Connector test set (V.A.G 1594C)

Procedure

• Oil level OK

• Engine oil temperature approximately 80° C.

- Remove oil pressure switch => [ Oil Pressure Switch ] Service and Repair.

- Connect oil pressure gauge (V.A.G 1342) with adapter (V.A.G 1342/14) to oil pressure switch hole.





- Install oil pressure switch to oil pressure gauge (V.A.G 1342).

Oil Pressure Switch, Checking

- Connect brown wire of oil pressure gauge to ground (GND).

- Connect voltage tester (V.A.G 1527B) using adapter cables from connector test kit (V.A.G 1594C) to oil pressure switch and battery plus ("+").

• LED must not light up.

- If LED lights up with engine at standstill, replace oil pressure switch.

- Start engine.

• Because the switch point for oil pressure switch can be exceeded upon starting, watch oil pressure gauge

• At 1.2 to 1.6 bar pressure, LED must light up.

- If LED does not light up, replace oil pressure switch.

Oil Pressure, Checking

- Start engine.

• Oil pressure at 1500 RPM at least 1.7 bar.

• Oil pressure at 2000 RPM at least 3.0 to 5.5 bar.

Assembling

- Install oil pressure switch => [ Oil Pressure Switch ] Service and Repair.
