The solution is: if the car heater valve fails, you need to go to the car's 4S shop or repair shop to repair the car heater valve in time to solve the problem that the car air conditioner is inconsistent.
The heating principle of Audi A6L car is to blow the heat from the heating water tank into the cab through the blower. If the air volume is insufficient or the distribution of cold and hot air is not good, the heat of heating the small water tank will not be dissipated, and the temperature of heating air will not come up.
Extended data:
The causes of heating failure of Audi A6L car are as follows:
Opening the thermostat too early will make the refrigeration system enter the big cycle too early. When the vehicle is running, the outdoor cold air will quickly cool the antifreeze, resulting in the engine water temperature not rising, and the warm air will inevitably not be hot. The impeller of the water pump is damaged or lost, so that the flow through the warm air small water tank is not enough and the heat cannot come up.
There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, high water temperature and not hot warm air. If there is gas in the cooling system all the time, it is likely that the cylinder pad is damaged and the gas leaks into the cooling system; Check that the outlet pipe of the heater tank is cold and the inlet pipe is hot, indicating that the heater tank is blocked.
