How to determine that the water valve of Audi a6l heater is broken?

When the temperature rises and the wind from the air outlet is not hot; Or when the warm air can't be turned off, the hot air still comes out of the air outlet after the temperature is reduced, or the temperature inside the car can't reach the constant temperature effect in the automatic mode of air conditioning. When these three situations happen, it can basically be judged that the warm air water valve is broken.

The warm air water valve is the warm air switch of the automobile heater. The radiator in the heater is connected with the circulating water of the engine through the water inlet and outlet pipes. The water valve is a switch. The water valve is opened, the waterway is connected, and the circulating water of the engine enters the radiator. The fan blows heat into the cab. Otherwise, the water valve is closed and the warm air doesn't work.

Precautions:

When the car starts, because the engine needs to drive the condenser and blower to start together, the fuel consumption will definitely increase at this time, which will also lead to the loss of battery power.

So, be sure to remember to turn off the heating when not in use. Even if the car is always on, it is not suitable for continuous heating, which will cause damage to the condensation system. It is suggested to shut down for a few minutes after 1 hour.
