1. Unscrew the oil switch (F1) And screw it into the manometer. Screw the pressure gauge into the oil filter holder instead of the oil switch.
2. Connect the brown lead of the tester to the housing.
3. Auxiliary wires with LED voltage indicator (e.g. VAG 1527 V) connect to the positive battery terminal and to the oil switch. If after that the LED lights up, the switch must be replaced.
4. If the LED is off, start the engine and slowly increase the speed. The LED should light up at an overpressure of 1.2...1.6 bar. If the LED does not light up, the oil switch needs to be replaced. The oil pressure at idle must be at least 2 bar.
To check the oil pressure and the oil switch, a pressure gauge is required, which must be able to screw in the oil switch A. The voltage indicator LED is connected to the positive terminal of the battery and the switch using auxiliary wires
5. Continue to increase speed. At a speed of 2000 rpm and an oil temperature of 80'C, the pressure should be at least 2.7... 4.5 bar. If the nominal values are not met, mechanical faults, such as damaged bearings, must be corrected. If necessary, replace the oil filter holder with safety valve or the oil pump.
6. At high speeds, the oil pressure must not exceed 7.0 bar. If the pressure increases to high values, check the lubrication channels and, if necessary, replace the oil filter holder with safety valve.
7. At the end of the test, unscrew the pressure gauge and reinstall the oil switch instead. The tightening torque is 25 Nm. In case of leakage, replace the seal (cut the old seal with side cutters).
