Where are the sunroof drainage holes located on the Tiguan L?
2 Answers
The sunroof drainage holes on the Tiguan L are located at the four corners of the sunroof. They can be seen after opening the sunroof, and each drainage hole is connected to a hose that directs water to the bottom of the car and drains it out. Taking the 2018 Tiguan L Comfort Edition as an example, it belongs to the midsize SUV category with body dimensions of 4712 mm in length, 1839 mm in width, and 1673 mm in height, with a wheelbase of 2791 mm. The 2018 Tiguan L Comfort Edition is equipped with a 1.4T turbocharged engine, delivering a maximum power of 110 kW and a maximum torque of 250 Nm. It adopts a front-engine, front-wheel-drive layout, with a front suspension using MacPherson struts and a rear suspension featuring a multi-link independent suspension.
In our auto repair trade, the sunroof drainage holes of the Tiguan L are generally located at the four corners around the sunroof glass, specifically at the junction between the sunroof frame and the roof seal. Each corner has a small hole. These holes are connected to thin drainage tubes that run down to the lower sections of the A-pillar and C-pillar, eventually draining out near the undercarriage or rear wheel arches. If the drainage holes get clogged, rainwater can backflow into the car, soaking the headliner or carpet, and even causing electrical issues. I must remind you not to use a high-pressure water gun for cleaning, as it may damage the tubes. Instead, it's best to use a small brush or thin wire to clear the holes and regularly check the sunroof tracks for dust or leaf buildup. Routine maintenance, like blowing out the grooves during car washes, can prevent problems. This upkeep is crucial, as the Tiguan L's drainage system is designed to be sturdy, but neglect can easily lead to trouble.
