Where is the air conditioning drain pipe located on the Audi Q3?

The air conditioning drain pipe of Audi vehicles is located directly beneath the evaporator unit of the car. Function of the air conditioning drain pipe: Primarily serves as an air conditioning drainage device, enabling timely water discharge to ensure normal operation of the air conditioning system. The drain pipe also functions to discharge water when the vehicle is stationary. While it may seem that the car is a relatively enclosed environment, this isn't due to superior airtightness but rather the well-designed drainage holes. Air conditioning system maintenance: The cabin air filter should be replaced regularly. Generally, replacement is needed when driving under urban road conditions. This not only keeps the intake system cleaner but also prevents reduced cooling efficiency caused by a clogged air filter. During summer, when there's a significant temperature difference between the interior and exterior of the vehicle, it's advisable not to immediately set the air conditioning to the lowest temperature upon entering the car.
While repairing my Audi Q3, I discovered the location of the air conditioning drain tube. It's hidden underneath the car, slightly towards the middle, specifically near the front of the vehicle under the driver's seat. This tube typically extends from the evaporator box of the AC system and leads directly outside to the ground, serving to drain condensation and prevent water accumulation inside the car. If you can't locate it precisely, try checking when the car's carpet is wet, as blockages are a common issue. Untreated blockages can lead to moldy carpets or unpleasant odors. For inspection and maintenance, it's best to lift the car or use a jack for safe access. A gentle clean with a soft hose can usually solve the problem. Regular cleaning of the tube can extend the system's lifespan. Remember to check it more frequently before the rainy season to prevent minor issues from becoming major problems.
