Where is the drainage hole of Audi A6?

The sunroof drainage holes are located at the A-pillar and C-pillar positions of the car. Regular cleaning: After prolonged use of the sunroof, a significant amount of sand particles often accumulate in its sliding tracks and gaps. If not cleaned regularly, these particles can wear down the sunroof components. It is advisable to frequently clean the areas around the sliding tracks to prevent sand accumulation and extend the service life of the sunroof sealing strips. Generally, after two to three months of use, the sealing strips or sliding tracks should be cleaned with gauze soaked in cleaning water. After wiping them dry, apply a small amount of engine oil or butter. Sunroof precautions: If the vehicle is to be parked for an extended period or the sunroof will not be used for a long time, apply a thin layer of talcum powder or a lubricant specifically designed for sealing strips around the sunroof. If the area around the sunroof is made of fabric, simply clean it with water and a clean cloth. Conduct a thorough cleaning once to prevent the sealing strips from undergoing chemical changes and aging due to prolonged exposure to air.
I drove an Audi A6 for several years, and the location of the drainage holes is crucial, especially in areas prone to water accumulation like the sunroof and doors. The sunroof drainage holes are usually located in the four corners. To find them, look up at the edges of the sunroof glass—there’s a small hole above the front wheels connected to a tube that leads down to the chassis behind the wheels. The doors also have small holes at the very bottom of the door panel, which can easily get clogged with dirt. For cleaning, I simply use a vacuum or a thin, soft tube to blow air through them—it’s easy and cost-effective. If you neglect cleaning these, a heavy rain can cause water to backflow into the car, soaking the carpets and leading to rust. I remember one spring when I forgot to check, and water got inside, costing me over a thousand to repair the electrical system. Now, I clean them every quarter, especially before and after seasonal changes. Overall, developing this habit saves both money and hassle—don’t slack off.
