| Screw the connection of the oil pressure tester -V.A.G 1342- with positioned gasket into the threaded hole for the oil pressure switch. |
| –
| Screw the oil pressure switch -2- into the oil pressure tester. |
| Test oil pressure switch -F1- |
| –
| Connect brown cable -1- of oil pressure tester to earth (-). |
| –
| Connect the voltage tester with the auxiliary cables from the measuring tool set to the oil pressure switch -F1- and to battery positive (+). |
| l
| The LED must not light up. |
| –
| Replace oil pressure switch. |
| If the LED does not light up: |
Note | Observe the testing equipment and the LED while actuating the starter since the switching point of the oil pressure switch -F1- can already be reached when starting up. |
| l
| At a pressure of 0.03...0.06 MPa (0.3...0.6 bar) the LED should light up. |
| If the LED does not light up: |
| –
| Replace oil pressure switch -F1- → Chapter. |
| l
| Oil pressure when engine idling: at least 0,08 MPa (0,8 bar) |
| l
| Oil pressure at 2000 rpm: min. 0,14 MPa (1,4 bar) |
| If the specified values are not reached, the oil pump is defective. |
| l
| Oil pressure at a higher engine speed: max. 0,52 MPa (5,2 bar) |
| If the specified value is exceeded, the pressure control valve in the oil pump is defective. |
Note | t
| After testing the oil pressure switch -F1- or after checking the oil pressure, remove the oil pressure tester -V.A.G 1342- and install the oil pressure switch -F1- with a new gasket ring → Chapter. |
| t
| The tightening torque of the oil pressure switch -F1- is 22 Nm. |
