Oil Pressure Switch and Pressure, Checking
Special tools, testers and auxiliary items required
‹› Oil Pressure Gauge (V.A.G 1342)
‹› Voltage Tester (V.A.G 1527/B)
‹› Connector Test Set (V.A.G 1594/C)
‹› Socket 24 mm and Jointed Extension (T40175)
Oil Pressure Switch, Checking
Test Conditions
‹› Engine oil level OK, checking. Refer to => [ Engine Oil Level, Checking ] See: Testing and Inspection/Component Tests and General Diagnostics.
‹› Engine oil temperature at least 80 °C (176 °F) (radiator fan must start up once).
-
Remove the oil pressure switch (F1) using (T40175) and install it into the (V.A.G 1342).
-
Thread the (V.A.G 1342) into oil filter bracket in place of the oil pressure switch.
-
Connect the brown wire from the (V.A.G 1342) to ground (-).
-
Connect the (V.A.G 1527B) using an adapter cable from (V.A.G 1594 A) to the battery positive (+) terminal and the oil pressure switch. The Light
Emitting Diode (LED) must not light up.
-
Start the engine and slowly increase the engine speed. The LED must illuminate at 0.55 to 0.85 bar. Replace the oil pressure switch if it does not.
Oil Pressure, Checking
-
Increase engine speed further. At 2,000 RPM and with the oil temperature at 80 °C (176 °F), the oil pressure must be a minimum of 2.0 bar.
At higher RPMs, the oil pressure must not exceed 7.0 bar. If necessary, replace oil filter bracket.
