Before diving into the replacement process, it's essential to understand the function of the heater core. The heater core is a small radiator located inside the dashboard of your car. It works in conjunction with the car's heating system to provide warm air to the cabin. The heater core circulates hot coolant from the car's engine, which heats up the air that passes through it, and then distributes it to the cabin.

Signs of a Failing Heater Core

If your Audi A6's heater core is failing, you'll notice some telltale signs. The most common sign is a lack of warm air blowing from the vents. You may also notice a sweet smell coming from the vents, which is caused by the coolant leaking from the heater core. In some cases, you may even notice a puddle of coolant on the passenger side floor.
