If the engine speed is less than 2000 rpm and at the same time the oil pressure drops below 0.3 bar, the warning signal on the instrument panel starts to flash. At speeds above 2000 rpm, the oil pressure must be at least 1.8 bar, otherwise the warning signal flashes and a buzzer sounds.
If the warning light flashes and the buzzer sounds while driving, the reasons may be:
- 1. oil level too low.
- 2. faults in the electrical circuits of the switch and warning signal.
- 3. The oil pump does not pump.
- 4. The propeller shaft bearing is faulty.
In this case, you should immediately turn off the engine and check the oil level, top it up if necessary. Then start the engine at idle speed, if the engine is too noisy, immediately turn off the engine and tow the car.
If there is no noise and the control lamp does not blink, increase the number of revolutions to more than 2000 per minute. If now the lamp does not blink and the buzzer is not heard, then the movement can be continued.

If the buzzer sounds and the warning light flashes, check the oil pressure regulator, see. "Oil circulation system fault table". If, however, the oil level is normal and the oil pressure regulator and its electrical circuits are in good working order, then under no circumstances should you continue driving, but should tow the bus.
Note: Replace seals regularly. All cooling system components can be removed and installed with the engine mounted.
