Where is the water leakage at the sunroof drainage hole of the Audi Q3?

[DiFrank]

Audi Q3 sunroof drainage hole leakage can be caused by blockage of the drainage hole or issues with the sealing strip. Below are the relevant explanations: Drainage hole blockage: Sand and dust in the sunroof drainage hole can cause it to clog. Regularly clean the sunroof to maintain cleanliness around the drainage hole. During car washes, use specialized air-blowing equipment to direct air toward the drainage pipe to remove dirt as much as possible. Sealing strip issue: The sunroof sealing strip may become displaced. This indicates excessive friction between the strip and the roof. You can apply plastic protective agents or talcum powder to the sealing strip and other components to reduce friction while maintaining the strip's sealing performance.
