Audi A3's sunroof drain hole is located next to the front windshield drain outlet. Below is more information about the Audi A3: 1. Powertrain: The sedan version of the A3 is the same as the hatchback version, equipped with 1.4TFSI and 1.8TFSI engines. The 1.4TFSI engine has a maximum power of 90kW, and it is expected to adopt the domestic 96kW power version of the 1.4TSI engine after being introduced to China. The 1.8TFSI engine has a maximum power of 132kW. 2. Interior: The domestically produced Audi A3 will improve its overall interior craftsmanship quality, with touch-function dashboard and soft high-quality materials being applied to the new generation models.

Last year, I bought an Audi A3 to drive, but I've been troubled by a leaking sunroof. Through my own exploration, I found that the drainage holes are mainly located at the four corners of the sunroof rails—one on each side near the A-pillar in the front, and one on each side near small gaps around the C-pillar in the rear. Opening the sunroof reveals these holes, which are about the size of a pinhead. They connect to plastic tubes that drain water near the wheels. I've learned that regular cleaning is crucial because leaves and dust can easily clog them. Before the rainy season, I use compressed air to blow them out or gently clear them with a thin wire. If not addressed promptly, water can accumulate inside the car, leading to a nasty mildew smell in the floor mats. Sometimes, I can even feel dampness around the seatbelt buckle area. Early maintenance can save a lot on repair costs.

As a technician frequently working with cars, I understand the importance of the sunroof drainage holes in the Audi A3. The holes are located at the junction of the front roof and the windshield—specifically at the front of the sunroof—with one on each side. To clean them, carefully open the sunroof and locate the holes. Use a soft, thin tube or a specialized cleaning tool to clear them. Prevention is key, as Audi's drainage design is relatively concealed. If clogged, water can seep into the car's electronic components, causing short circuits. It's recommended to inspect them every six months, especially in areas with a lot of willow catkins in the north. If you notice minor leaks during heavy rain, don't panic—first try blowing the holes clean. Proper maintenance can extend the sunroof's lifespan.

With over a decade of driving experience, I've noticed that the sunroof drainage holes on the Audi A3 are located at all four corners of the sunroof frame, making them easy to locate. Simply open the sunroof to spot the holes—the front two are near the windshield, while the rear two are adjacent to the rear roof edge. During DIY maintenance, avoid poking them with hard objects to prevent damaging the drainage tubes. These holes serve to channel rainwater to the underside of the car, preventing water accumulation that could corrode the body. In cold weather, watch out for ice blockages, and it's advisable to do a quick clean before the rainy season in southern regions. Practically speaking, keeping a small soft brush in the car does the trick—just a few swipes can prevent leaks.
