What are the reasons for the Lavida sunroof leaking?

[MacLorenzo]

Volkswagen Lavida sunroof leakage may be due to a problem with the drainage system. Sunroof leakage treatment method: Turn on the vehicle's ignition, start the sunroof switch button, so that the sunroof opens. First, observe the car's sunroof. At the track of the car sunroof, there is a drainage outlet, one on each side. Add water at this drainage outlet to observe whether the drainage pipe is clear. Both sides need to be checked. Car maintenance: Pay special attention to the dust-proof work of the sunroof sealing ring in daily use. In spring and autumn, you can clean the sealing ring once a quarter with a wet sponge. Before long-term parking of the vehicle, use talcum powder to thoroughly clean the sunroof once to avoid chemical changes and natural aging of the rubber strip in the air over time.
