Where is the sunroof drain outlet of Audi A6 located?
2 Answers
Audi A6's sunroof drain outlets are located on both the left and right sides of the joint where the sunroof closes when fully opened. The functions of a car sunroof include the following points: 1. Rapid cooling: Opening the windows and sunroof while driving allows air convection for quick cooling. 2. Fog elimination: In seasons with significant temperature differences, if the side windows are closed while driving, the front windshield can easily fog up. At this time, simply opening the sunroof for a few seconds can quickly eliminate the fog. 3. Quick air refresh: Opening the sunroof while driving can rapidly increase the speed of air circulation inside the car, thereby improving ventilation in the cabin.
I've worked in repair shops for many years and often get Audi A6 owners asking about the location of the drainage outlets. They are typically at the four corners of the sunroof frame, near the upper ends of the A-pillars and C-pillars. The drainage tubes run along the pillars down to the bottom of the car to discharge rainwater. If they get clogged, water can backflow into the cabin, soaking the carpets and damaging electronic components. Don’t underestimate this—regular maintenance is crucial. Before the spring and summer rainy seasons, use an air pump to blow through the tubes to prevent leaves or dirt buildup. Some older A6 models have drainage outlets near the sun visors, which are easy to overlook. If you notice a leak, check the drainage outlets first instead of rushing to replace the sunroof—it saves both money and hassle. Remember, the outlets aren’t too hidden; just lift the sunroof seal to spot them. Keep an eye out for musty smells inside the car—that’s a telltale sign of a clog.
