What are the causes and solutions for sunroof leakage in the Tiguan?

[ArianaLee]

Tiguan sunroof leakage can be attributed to three main causes: 1. Blockage of the sunroof drainage outlets by debris, preventing rainwater from draining and causing it to seep into the vehicle interior. 2. Damage to the sunroof sealing strip, resulting in poor edge sealing and allowing rainwater to enter the cabin. 3. Gaps in the Tiguan's sunroof frame, leading to rainwater infiltration. Solutions for Tiguan sunroof leakage are as follows: 1. Pour some water into the sunroof drainage channel and check if water flows out under the front tires. If water flows out, it indicates the drainage outlets are clear; use a towel to clean the outlets thoroughly to ensure proper rainwater drainage to the ground. 2. If the sunroof sealing strip is damaged, replace it with a new one. Remove the front and rear sealing strips of the sunroof glass, then carefully adhere the new strip along the perimeter of the vehicle's edges.
