1. After oil change, when the car needs to be refueled to normal temperature, turn off the engine and wait for about 2 minutes to measure the oil. The engine oil temperature needs to reach more than 60 degrees, that is, start the car for more than 10 minutes, and then turn off the engine for 1 minute. On the display screen of the central control unit, press the car key to see it.

2.If the vehicle is short of oil, there will be an icon like an oil pot on the instrument panel. If the amount of oil added exceeds the official standard (usually 5L), reset the oil maintenance light first. As soon as the oil is reset, the display screen immediately shows that the oil quantity is too much, and the instrument does not show that the oil quantity is insufficient. It is necessary to pump the oil to the standard value.Under normal driving mode, if the pointer swings within the middle range of the dial, it indicates that the engine has reached operating temperature. When the engine load is heavy and the outside temperature is high, the pointer may also deflect to the right. At this time, do not mind as long as the warning symbol V in the instrument cluster display does not light up.

The Audi A4L displays the oil temperature. In the instrument panel, only the oil temperature can be seen when switching the display interface. The sensor of the water temperature gauge is a thermistor sensor, which is fixed on the engine cooling water channel with threads.In the past, tap water was used as the cooling water of automobile engines. Now many automobile engine cooling systems use special coolant, so it is also called coolant thermometer.
Automobile water temperature standard.

The indication marks of the water temperature gauge on the automobile instrument panel are different, but the judgment standards of the water temperature are the same. The general indication is in the middle, about 90 degrees Celsius. The lower the engine coolant temperature is, the better. The higher the engine coolant temperature is, the better. It needs to be within a certain range. The normal temperature is 90 ° C in the center of the pointer. When the air conditioner is turned on, the water temperature is high, because when the air conditioner is turned on, the idle speed of the engine will automatically increase, so as to emit more heat. When the car stops, the cooling speed by the fan is not enough. However, this will not happen in ordinary cars, because there is a temperature controlled fan. The long-term high water temperature will reduce the lubrication function of the engine lubricating oil, resulting in the wear of internal parts of the engine.
