What to do if the sunroof of the Tiguan L leaks?

[AllieMarie]

The drainage outlet of the sunroof is blocked by debris, preventing rainwater from draining and causing it to gradually seep into the car. Simply clear the drainage channel of the sunroof. The sunroof seal is damaged, resulting in poor edge sealing and allowing rainwater to enter the car. Replace it with a new sunroof seal. There are gaps in the sunroof frame of the Tiguan, causing rainwater to seep into the car. This usually happens during heavy rain. The most direct solution is to replace the sunroof frame.
