Oil Pressure Sender: Testing and Inspection
Oil Pressure and Switch, Checking
Special tools, testers and auxiliary items required
‹› Oil Pressure Gauge (V.A.G 1342)
‹› Voltage Tester (V.A.G 1527B)
‹› Connector Test Set (V.A.G 1594C)
‹› Socket 24 mm and Jointed Extension (T40175)
Requirements:
‹› Engine oil level OK
‹› Engine oil temperature at least 80 °C (176 °F) (radiator fan must start up once).
‹› For the functional check and servicing of the optical and acoustic oil pressure warning: wiring diagrams, refer to "Function and Component
Selection" in the vehicle diagnostic tester.
Test Sequence
‹› Tightening specifications, see - item 2 - in => [ Oil Filter, Cooler and Pressure Switch Overview ] See: Engine, Cooling and
Exhaust/Engine/Engine Lubrication/Oil Filter/Service and Repair.
-
Remove the oil pressure switch (F1) 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 adapter cables from (V.A.G 1594C) to B+ and the oil pressure switch. The Light Emitting Diode (LED) must
not light up.
-
If the LED lights up, replace the oil pressure switch.
If the LED does not light up:
-
Start the engine and increase the RPM: the LED must come on at 1.2 to 1.6 bar pressure; if not, then replace the oil pressure switch.
-
Increase the engine speed further. At 2000 RPM and an oil temperature of 80 °C (176 °F), oil pressure must be between 2.7 and 4.5 bar.
At higher engine speeds the oil pressure must not exceed 7.0 bar
