Where is the drainage outlet located on the Tiguan?

Volkswagen Tiguan's sunroof drainage outlets are located on the lower inner side of the A-pillars. Relevant details are as follows: 1. Drainage outlets: The sunroof drainage outlets of a car are generally well concealed, and their positions vary depending on the model. They are usually distributed inside the A-pillars and C-pillars of the vehicle, with a round rubber cover. The rear ones are located on both sides of the rear longitudinal beams, one on each side. When water enters the sunroof channel, it flows to the drainage holes and then exits the vehicle through the drainage pipes. 2. Blockage occurrence: If the sunroof drainage outlets become blocked, they can be cleared using high-pressure airflow. Use an air pump to direct high-pressure airflow at the drainage holes of the two front drainage pipes inside the sunroof to clear the pipes. Remember to cover with a cloth to prevent strong airflow from splashing dirty water onto yourself or the interior of the car. Also, ensure the air pressure is not too strong, as it could cause the rubber connectors and drainage pipes to detach, leading to severe water leakage.
As an ordinary Tiguan owner, I've encountered the annoyance of clogged drainage outlets, which are located at several key points: the sunroof drainage outlets are designed at the left and right corners beneath the windshield, and you can find the openings along the gaps of the A-pillars; the door drainage outlets are at the bottom edges of each door, featuring small holes or groove designs; the drainage points in the trunk are near the spare tire well or small holes around the rear bumper. I've noticed that if water seeps into the car during rain, it's mostly because these spots are blocked—accumulated leaves or dust prevent water from draining, causing it to flow into the cabin and soak the carpets or damage the wiring. That time when my car's carpet got moldy, I learned to regularly clean these spots with thin wire or compressed air. I recommend checking them every six months, especially for cars parked under trees or during the rainy season, as they are more prone to clogging. Such simple maintenance can save you a lot on repair costs and protect the interior environment.
Having worked in car repair for a long time, I'm familiar with the drainage system layout of the Tiguan: the sunroof drainage outlets are usually hidden in the corners where the windshield meets the roof, with guide tubes connected to the A-pillar; the door drainage holes are directly at the bottom of the door frame, appearing as small slits; the trunk drainage is located in the spare tire well or along the edges of the rear tailgate. The most common issue is blockage by debris, such as mud or tree fruits clogging the openings, causing water to back up and wet the seats or corrode the metal. When dealing with it, gently use a poking tool or water gun to flush it out—avoid forcing it to prevent damage. Neglecting these can lead to mold or short circuits, making repairs quite troublesome. I remind customers to check these during car washes to keep them clear.
