What will be the impact if the additional water pump leading to the heater water tank of Audi A4L is broken? Will there be no warm air?

If the additional water pump leading to the heating water tank is broken, it will cause the water in the heating water tank to no longer circulate. The water temperature in the part of the pipe close to the radiator will increase, while the water temperature in other parts will decrease;

Since the heat source of the warm air comes from the engine coolant, and the coolant needs the pressure generated by the water pump before it can circulate in the warm air tank. Due to the damage of the water pump, the water no longer circulates, causing the warm air to disappear or not warm. .

In winter, if the additional water pump of the heating water tank is broken, it needs to be repaired in time to prevent the heating system pipes from freezing and causing the heating pipes to burst.

Water heating system

Water heating systems are mostly used in cars, large trucks and buses with low heating requirements. The water heating heating system mainly consists of a heater, a hot water regulating valve, a blower, a control panel, etc.

Among them, the heat source comes from the engine coolant, and the blower consists of an adjustable-speed DC motor and a squirrel-cage fan. Its function is to blow cold air to the heater, and the cold air is heated and sent into the car. By adjusting the speed of the motor, the amount of air supplied to the cabin can be adjusted.
