Checking sensors and oil pressure
Check oil pressure gauge 0,3 bar With 2 oil pressure sensor, actuated by different oil pressure. Oil Pressure Switch 0,3 bar is colored brown; oil pressure of 1.8 bar has a white insulation. Instead, oil pressure of 1.8 bar, the diesel engine has a sensor 0.9 bar with a gray insulation. 4-cylinder engine
Oil Pressure Switch 0,3 bar is located on the front side of the cylinder head to the left in the engine compartment. Oil pressure switch 1.8 / 0.9 bar screwed on top of the oil filter bracket. 5-cylinder engine
Both the oil pressure sensor located on the left side of the cylinder bore to guide the oil dipstick.
| PERFORMANCE ORDER | | 1. Check the oil level. | | 2. Check the wiring of both the oil pressure sensor according to the wiring diagram. | | 3. Remove the oil pressure of 0.3 bar (brown insulation). | | 4. Instead of the oil pressure sensor gauge screw fitting. | | 5. If using the meter VW, screw the oil pressure gauge to the test instrument. |
A warning  The above test can be made if only it is possible to screw the sensor into a pressure gauge. Otherwise, it can only be checked sensors 1.8 / 0.9 bar.
| | 6. Connect the tester to earth (-). | | 7. Connect using an additional wire, a device for measuring the voltage (multimeter or diode LED) to the oil pressure switch 0.3 (A) and the positive terminal of the battery. | | 8. Control lamp or light emitting diode should light up. | | 9. Start the engine and gradually raise the speed. | | 10. Once the gauge reads 0,15-0,45 bar, but no more, the control lamp goes out. Otherwise, the oil pressure of 0.3 bar to replace. |
A warning If necessary, check the response time of the oil pressure sensor when the motor starter.
| | Oil pressure switch 1.8 / 0.9 bar | | 11. Disconnect the wiring from the sensor 1.8 / 0.9 bar (white / gray insulation). | | 12. With the help of additional wires to connect the device for measuring the voltage (multimeter or diode LED) to the oil pressure switch 1.8 / 0.9 bar and the positive pole of the battery. | | 13. The control lamp should not burn. | | Oil Pressure Switch 1,8 bar | | 14. Raise the momentum until the gauge indicates 1.6 to 1.8 bar. Now, the test lamp should light up, otherwise, replace the oil pressure switch. | | Oil Pressure Switch 0,9 bar | | 15. Raise the momentum until the gauge indicates 0.75 to 1.05 bar. Now, the test lamp should light up, otherwise, replace the oil pressure switch. |

Checking oil pressure
| PERFORMANCE ORDER | | 1. Raise the engine speed to 2000 rev / min. Oil temperature 80 ?� C, the oil pressure at these speeds should be not less than 2.0 bar. | | 2. Lower oil pressure indicates wear of crankshaft main bearings. | | 3. Raise the pace is even higher. Oil pressure must not exceed the maximum permissible value. Otherwise, replace the oil pump with the pressure relief valve. | | 4. Install the oil pressure gauge with a new sealing ring and tighten to 25 Nm. |
|
The maximum permissible oil pressure Engine | The maximum oil pressure, bar | 4-cylinder engine | 7.0 | 5-cylinder engine | 5.3 - 6.3 |
