How to Solve the Problem of Lavida Sunroof Leaking Water Flowing into the Cabin Along the B-Pillar?

There is a drainage outlet on the sunroof track of the car, one on each side. Pour water into this drainage outlet to observe whether the drainage pipe is clear. Both sides should be tested, and once unclogged, the leakage will stop. Below is relevant information: 1. Lavida: The Lavida is a sedan produced by Shanghai Volkswagen, launched in June 2008. While continuing the design language of "dynamic and stylish" in the A-segment car market, the LAVIDA Lavida embodies a new design DNA—"fusion." 2. Sunroof: The car sunroof is installed on the roof, effectively facilitating air circulation inside the car and increasing the intake of fresh air. Additionally, the car sunroof can broaden the view and meet the needs of mobile photography and videography.
I've encountered the issue of the Lavida's sunroof leaking water that flows down the B-pillar into the cabin multiple times. The main cause is clogged sunroof drainage holes—those small openings in the corners of the sunroof are prone to blockage by leaves and dust. When water accumulates with no way out, it seeps into the car along the B-pillar. The solution is straightforward: first, open the sunroof and carefully inspect the edges. Use a thin wire or a specialized brush to clear the drainage holes. If it still leaks after unclogging, check if the drainage tube is disconnected or cracked, especially near the B-pillar, as this is where the tube runs downward. A simple test is pouring water to observe the flow. For regular maintenance, it's advisable to clean the sunroof every few months, particularly during rainy seasons. Also, inspect the sealing rubber strips—replace them if they’re aged to avoid water accumulation affecting electrical safety. In short, if you’re handy, you can handle it yourself, but be meticulous to avoid scratching the car body. Prevention is better than repair—just avoid parking under trees.
After driving a Volkswagen for a long time, sunroof leaks are quite common. For the Lavida, this situation is usually caused by a drainage system failure. Water enters along the B-pillar, mostly due to a rupture or disconnection in the drainage pipe that runs from the A-pillar to the bottom of the car, leading to water accumulation and overflow. DIY solution steps: First, clean the sunroof drainage holes, use an air gun to blow air or rinse with water to test for smoothness. Then, remove the B-pillar interior trim to check if the pipe connection is loose, and replace it with a new pipe if necessary. Buying parts online isn't expensive, just a few dozen yuan. For prevention, avoid parking under big trees and regularly wipe the sunroof tracks with a damp cloth. DIY can save you hundreds, but be careful not to damage the interior, especially since there might be wiring inside the B-pillar—if problems arise, seek professional help immediately. Don't wait until the interior gets moldy to take action; fixing it early saves you trouble.
