Rather, the red light comes on when the oil PRESSURE drops too low as determined by an oil pressure switch installed on the engine. No VW van ever came from the factory with an oil pressure gauge or oil level indicator, just a low oil pressure warning light. One-switch system: 1948-1985.
The oil pressure sending unit controls the oil pressure light or gauge depending on which you car is equipped with. When oil pressure is applied, the switch contacts either shut off the oil light or make the oil pressure gauge active. Basically, the oil pressure sending unit is what sends the oil pressure information to the carâs computer, which then controls the related lights and gauges.
