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.
Inside the oil pressure sensor is a diaphragm that touches a ground wire when there is little or no oil pressureâthis is what causes the warning light to illuminate. When the engine is running, the oil pressure pushes against the diaphragm and disconnects the ground to the warning light, turning it off.
