How to act when the standard Audi A6 stove does not heat well
Content
If the Audi A6 C5 stove does not heat well, then you should not put off the problem until the onset of cold weather. It is advisable to start repairs in advance, when it is still convenient to carry out assembly and disassembly work with the car in the garage.
Design features of the heating system
It is problematic to find out what to do with the work of the Audi A6, when the stove is weak or practically does not explode without disassembly operations. An extensive network of channels must distribute the hot air flows created by the radiator. The electric motor and drive unit are responsible for the forced feed.
Important! In order for the system to pump hot air in the right direction into the cabin, the design provides for five controlled dampers.
The three dampers (1, 2, 3) inside work together. Its simultaneous operation contributes to the penetration of hot and cold air to the driver and passengers. Simultaneous control is provided by a cable that is connected to a rotary shim in the Hot-Cold compartment.

Two more dampers (4, 5) also work in parallel and help distribute air flows in the following directions:
- at your feet;
- in the center;
- from inside the windshield.
If the control of this pair is knocked down, then the Audi A6 C5 stove does not heat up, and the “center-legs-glass” switch washer does not perform its functions. Problems can be heard right away.
It should be noted that the designers provided for damper No. 1 a small gap even with the most “hot” position of the control washer. Thus, not only warm air, which is problematic for breathing, enters the cabin, but also part of the cold air from outside, which increases comfort.
Potential performance problems
Power is supplied to the electric motor through convenient sockets. In the motor housing there is a speed control unit with resistors. When the Audi A6 C5 stove does not work, you need to check its condition and connection.

Cabling may be the culprit. If the Audi A6 C4 stove does not heat up, the reason may lie in the disconnected wires. For its fastening, factory fastenings are provided with bolts through a threaded hole.
Sometimes the stove blows weakly on the Audi A6, but the car enthusiast does not know what to do. The problem may be hiding in the idle switch. Carbon deposits form on the contacts, opening the electrical circuit. We recommend that you check the knot and clean the places of plaque. For this work, fine sandpaper and a riveting clerical knife are suitable.
Also, after disassembly, it is worth doing the following work:
- we check the operation of the valves that are in the hoses, the supply and return of the refrigerant;
- visually check the condition of the electrical connections, the connectors must be well connected and not have carbon deposits;
- control channels for patency;
- checking the operation of the pump.
Warm liquid should flow through the channels, which will be a test of the system's performance. This means that it is not heavily clogged with scale.

Preventive measures
In the event that the standard Audi A6 C5 stove blows exceptionally cold air, it is worth removing the radiator and flushing it. You will need a special pump that drives washer fluid through the cavity, dissolving any limescale deposits on the walls.
The event lasts about an hour, until the liquid, which has almost completely collected dirt, begins to circulate freely. After installing and assembling the radiator with the system, you will need to expel air from the cavities. To do this, turn on the gas with the plug of the antifreeze expansion tank open.
Sometimes the pump gets stuck. This leads to poor circulation of antifreeze and cold air from the deflector. The problem is solved by replacing the water pump with a new one.
The driver should check the level of antifreeze. Otherwise, lack of liquid will affect the operation of the heater.
Conclusion
Even with minor problems with heating, do not delay the repair of the system. When replacing defective items, such as a radiator, pump or electric motor, it is not recommended to purchase them without a quality certificate. Parts of well-known brands will last much longer than cheap fakes.
