Oil Pressure and Oil Pressure Switch (F1), Checking

Special tools, testers and auxiliary items required

• Oil Pressure Gauge (V.A.G 1342) and 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 (176 °F)

- Remove the oil pressure switch. Refer to => [ Oil Pressure Switch (F1) ] Service and Repair.

- Install the (V.A.G 1342) with (V.A.G 1342/14) into the hole for the oil pressure switch.

- Install oil pressure switch - 2 - in (V.A.G 1342).

- Attach the brown wire on the oil pressure gauge to the ground.

Oil Pressure Switch, Checking

- Connect the (V.A.G 1527B) using adapter cables from the (V.A.G 1594C) to the oil pressure switch and battery positive.

• LED must not light up.

• If the LED lights up, then the oil pressure switch must be replaced.

- Start the engine.

• Because the switch point for the oil pressure switch can be exceeded when starting, watch the oil pressure gauge and LED when starting the engine.

• The LED must illuminate at 1.2 to 1.6 bar.

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

Oil Pressure, Checking

- Start the engine.

• Oil pressure at idle: at least 1.5 bar.

• Oil pressure at 2000 RPM: at least 3.5 bar.

Assembling
