How to Deal with Water Leakage in the Tiguan's Sunroof?
2 Answers
Tiguan's panoramic sunroof water leakage can be addressed by regularly cleaning the drainage holes and using a small hook to remove debris from the holes. Below is a detailed analysis of the specific causes of panoramic sunroof water leakage: 1. Blocked Sunroof Drainage Holes: Blocked drainage holes prevent rainwater from flowing smoothly, leading to gradual seepage into the vehicle. This issue primarily arises when owners neglect regular cleaning of the roof, allowing debris to flow with rainwater and clog the drainage holes. To resolve this, you can use a wire to create a hook and remove the debris from the drainage holes. Alternatively, a repair shop can use an air gun to blow out the debris from the drainage holes. 2. Damaged Sunroof Seal: The sunroof seal is made of rubber and can deteriorate over time. Repeated friction from the sunroof glass can cause damage, resulting in poor sealing and water leakage during rainy weather. To prevent this, regularly inspect the seal for signs of aging and replace it promptly if damaged. Choose a seal with good performance, resistance to aging, and corrosion. 3. Roof Deformation: If the vehicle has been involved in a collision, the body may deform. If not properly restored during repairs, it can lead to poor sealing and water leakage. When repairing an accident-damaged vehicle, it is crucial to adhere strictly to the original vehicle standards. Otherwise, parts may not fit properly, creating potential leakage issues.
My Tiguan also had a water leakage issue before, which was quite annoying. At first, I thought the dampness inside was due to leaving the windows open in the rain, but later found out it was a sunroof problem. In most cases, it's caused by clogged drainage holes where dust and leaves get stuck, preventing rainwater from draining and causing overflow into the car. I fixed it myself: use a thin wire or compressed air to clear the drainage pipes. There are small holes at the four corners of the sunroof—just poke them to clear the blockage. If the sealing strip is aged, you can buy a new one online and replace it, but be careful not to damage the glass during the process. A reminder: if left unrepaired, water leakage can lead to moldy interiors and damage to electronic systems. Once, I delayed the repair and ended up having to replace the seats, costing me more. It's advisable to regularly clean the sunroof channels to prevent recurrence.
