How to reset the oil level warning in Volkswagen vehicles?
1 Answers
Volkswagen oil level reset method is as follows: 1. Keep the engine turned off, turn the ignition switch to the ACC position; 2. Within 5 seconds, slowly press the accelerator pedal all the way down and release, repeat three times; 3. Turn off the ignition switch, then start the vehicle. If the oil light is on but there is no oil shortage, it may be caused by other reasons: 1. Excessive oil viscosity: The viscosity of the oil is closely related to its quality. The higher the viscosity, the better the oil's resistance to high temperatures, and vice versa. However, higher viscosity is not always better; you should use an oil grade that matches your engine. 2. Pressure relief valve clogged or improperly adjusted: To prevent excessive oil pressure in the lubrication system, which increases engine power consumption and causes oil leaks at sealed connections, a pressure relief valve is installed in the main oil passage or oil pump. Its function is to limit the oil pressure in the lubrication system to not exceed the specified value. A faulty pressure relief valve can cause abnormal oil pressure, triggering the oil light. 3. Engine overheating: If the engine cooling system has excessive scale, poor heat dissipation, prolonged overload operation, or if the fuel injection pump's fuel supply timing is too late, the engine may overheat, accelerating oil aging, deterioration, and thinning, leading to leakage through various clearances, pressure drop, and the oil warning light coming on.
