4.6.1
Engine Oil Pressure, Checking
Special tools and workshop equipment required
♦ Oil Pressure Gauge Kit - VAG1342-
♦ Socket and Jointed Extension - 24mm - T40175-
Test Prerequisites
• Oil level OK
• The engine oil temperature at least 80 °C (176 °F) (the coolant
fan must start up once).
Note
♦
The oil pump is regulated and has two pressure stages. The
pressure stages are checked one after the other.
♦
During the break-in phase or in engine emergency running
mode the oil pump only pumps in the higher pressure stage.
♦
The oil pressure depends on the engine oil temperature. At an
engine oil temperature of 80 °C (176 °F) approximately the
average must be reached.
– After installing new parts (engine/partial engine, cylinder head
or turbocharger) limit the oil pressure regulation for approxi‐
mately 1000 km to the higher pressure stage. From this, the
higher friction is taken into account when breaking in new
components, and the optimum removal of particles from the
initial wear in is ensured. To do this connect the vehicle diag‐
nostic tester, switch on the ignition and select the following
menu items:
♦
01 - Engine electronics
♦
Guided functions
♦
01 - Oil Pressure Regulation/Retraction Activating
Test Sequence
– Disconnect the electrical connector -arrow- on the Reduced
Oil Pressure Switch - F378- .
– Place a cloth under the accessory assembly bracket to collect
leaking engine oil.
– Remove the Reduced Oil Pressure Switch - F378- -1-.
– Screw the Oil Pressure Gauge Kit - VAG1342- into the oil filter
bracket in place of the oil pressure switch.
– Push the Reduced Oil Pressure Switch - F378- in the Oil Pres‐
sure Tester and connect the connector.
– Connect the Oil Pressure Tester to the ground.
– Start the engine and check the oil pressure of the specified
RPMs.
• Oil pressure at idle: 0.85 to 1.6 bar (12.3 to 23.2 psi)
• Oil pressure at 2,000 RPM: 1.2 to 1.6 bar (17.4 to 23.2 psi)
• Oil pressure at 3,700 RPM: 1.2 to 1.6 bar (17.4 to 23.2 psi)
– Turn off the engine.
– Remove the noise insulation. Refer to ⇒ Body Exterior; Rep.
Gr. 66 ; Noise Insulation; Overview - Noise Insulation .
