Where is the drainage hole of the Tiguan door?

The drainage hole of the Tiguan door is located below the door panel, on the outer side of the sealing strip. Methods to prevent clogging of the drainage pipes are as follows: 1. During daily use, clean the obvious leaves and debris near the drainage holes inside the car. 2. Fine mud or debris may be hidden in the hoses or pipes. In addition to visually inspecting the drainage holes, it is also necessary to check the drainage pipes. Methods to unclog the drainage pipes are as follows: 1. Determine the location of the clog: For example, if there are water stains near the car roof and sunroof, it can basically be concluded that the problem comes from the sunroof. 2. Clean the debris: When cleaning the sunroof or other hidden hoses inside the car, avoid using hard objects such as iron wires to unclog them, as these hard objects may cause the hoses to break or detach.
I recently researched the drainage holes on the Tiguan when washing my car. They are located right at the bottom edge of each door and can be easily seen by looking down. The design is quite clever – there are usually two or three small holes shaped like narrow slits or tiny dots. Normally, you can see dust accumulating there when opening and closing the doors, and rainwater flows out through these holes. If leaves or twigs block them, water can accumulate under the doors, leading to rust in severe cases. I usually use a thin wire or toothpick to clean them out regularly. The Tiguan's drainage holes are relatively easy to locate, and you can also inspect them from the inside by lifting the sealing strip, but be careful not to damage the rubber seal.
I've fixed quite a few cases of water leakage in Tiguan doors. The drain holes are mainly located at the very bottom of the door. Typically, there are two positions for both front and rear doors - one near the door lock side and another near the door hinge side. You can spot these elongated openings by crouching down. These holes are designed to prevent rainwater accumulation inside the door that could corrode components, but they often get clogged with mud and sand. Many people don't realize that summer door leaks when parked under trees are usually caused by blocked drain holes. It's recommended to use an air gun to blow them out or carefully poke through them with a thin rod before each rainy season. Place a cloth underneath to catch debris when cleaning. The Tiguan's drain tubes aren't very long, making this maintenance relatively straightforward.
