What are the reasons why the air conditioning in the Audi Q3 is not cooling well?

Audi Q3 air conditioning not cooling well reasons introduction: Excessive refrigerant causing insufficient cooling. For excessive refrigerant, it is usually caused by overfilling during maintenance, as the proportion of refrigerant in the air conditioning system has specific requirements. If the proportion is too high, it can affect heat dissipation, meaning more heat dissipation leads to greater cooling capacity; conversely, less heat dissipation results in smaller cooling capacity. Below are three reasons: 1. Condenser issue: When the car is moving, the condenser has higher wind speed and better heat exchange efficiency, leading to better performance. At idle, the temperature around the condenser is high, the wind speed is low, and the refrigerant cannot cool down effectively, resulting in poor performance. 2. Condenser not dissipating heat leading to poor cooling: Especially the gap between the condenser and the radiator, if not cleaned for years, it may become completely blocked. In this case, the high-pressure air pump needs to be blown or removed for cleaning. 3. Lack of refrigerant: This leads to insufficient refrigerant in the air conditioning system pipelines, reduced pressure, and decreased heat absorption capacity.
