Volkswagen is still cool and can't get the water temperature and oil temperature up.

This may be due to a thermostat failure.

The failure of automobile water temperature may be caused by thermostat failure, water temperature sensor failure or cooling fan failure, and another case is caused by low temperature. Try to avoid violent driving when the water temperature is low, because it will lead to increased wear and tear of engine mechanical parts and affect engine life.

The temperature is low. In winter, the temperature of the refrigerant is relatively low, which makes it difficult for the water temperature to rise, and it takes a long time for the water temperature to rise. This kind of situation is the most common in winter, which is a normal phenomenon.
