A problem with the heating radiator of the Audi A3 Sportback.

Model: Audi A3 Sportback MK 3 - Years 2012-2019
Part: Heater core

On the Audi A3 Sportback, especially on the 2.0 TDi version, there is a known issue with the internal heating radiator, where particles and deposits can form due to the glycol circulating inside, causing blockages and significantly reducing the efficiency of the heating system. The most obvious symptom is a noticeable decrease in the air temperature coming out of the ventilation ducts, even when the temperature is set to the maximum. If the problem is not fixed, it can eventually lead to the burning of the engine head gasket, with potentially serious consequences. The ultimate solution is to replace the radiator, but a complete cleaning of the system must also be carried out using a special liquid that can only be found at Audi, designed to remove the deposits that have formed in the system.
