How to deal with Q5 sunroof leakage?
2 Answers
There are two drainage pipes in front of the sunroof. For Volkswagen vehicles, the drainage pipes generally have a cross-shaped head, which opens during drainage and closes when not draining. Over time, the rubber may age or mud may block the pipes, causing poor drainage. You can squeeze the drainage pipe head to remove the mud or cut it off.
I was really worried when I encountered a sunroof leak. After that heavy rain, there were water stains all over the car interior, and the seats were completely soaked. Upon inspection, I found the drainage holes were completely blocked. I gently cleaned the small holes in the corners using a toothbrush and a small brush, then used a hairdryer to dry the water stains to prevent mold. If the drainage tubes can't be unclogged, it might be due to aging sunroof seals losing their effectiveness—just buy new seals and replace them yourself. If the frame is severely deformed, you'll need to seek a professional technician for repairs. Since then, I've developed a habit of wiping dust from the sunroof edges every month and rinsing the drainage holes with water during car washes. The drainage system is crucial; otherwise, accumulated water can corrode the car's electrical circuits and shorten component lifespans. Regular maintenance saves hassle and money, and you can enjoy the sunroof with peace of mind. Don't wait until the rainy season when the problem worsens.
