Where is the rear sunroof drain outlet located on the Tiguan?
1 Answers
The rear sunroof drain outlet on the Tiguan is located inside the vehicle's A-pillar and C-pillar. When water enters the sunroof channel, it flows to the drain hole and then exits the vehicle through the drain tube. To locate the drain hole, you need to open the sunroof. Inside the drain hole, there is a tube running through the A-pillar, which allows water from the sunroof to flow down to the underside of the vehicle. The sunroof drain outlet is usually quite hidden, and its position varies depending on the vehicle model. If the sunroof is leaking, you should check whether the drain outlet is clogged with dust. Under normal circumstances, you should investigate the cause of the leakage, which could be due to one of the following three reasons: 1. The sunroof drain outlet is blocked by debris, preventing rainwater from draining and causing it to seep into the cabin. The solution for this issue is relatively simple—just clear the sunroof drain channel. You can open the sunroof, pour some water into the channel, and check if water flows out from under the front tires. If water flows out, it means the drain outlet is clear. Alternatively, you can use a towel to clean the drain outlet to ensure rainwater drains properly to the ground. 2. The sunroof seal is damaged, leading to poor edge sealing and allowing rainwater to enter the cabin. For a damaged sunroof seal, you need to replace it with a new one. This process is quite complex, as it requires removing both the front and rear sunroof glass panels and then carefully adhering the new seal around the edges of the sunroof. This task requires a certain level of technical skill. 3. There are gaps in the sunroof frame, causing rainwater to seep into the cabin. This usually happens during heavy rain. Fixing this type of leakage is very complicated. Applying some sealant to the sunroof frame may help, but it is quite challenging. If the vehicle is still under warranty, the most straightforward solution is to replace the sunroof frame. A professional technician typically needs about three days to complete this job, but once the sunroof frame is replaced, the leakage issue will be resolved.
