Where is the sunroof drain hole of the Tiguan?
2 Answers
The sunroof drain hole of the Tiguan can be found by the owner below the A-pillar, which is somewhat concealed. The design is discreet to maintain the aesthetic appeal of the Tiguan's panoramic sunroof while effectively draining rainwater, achieving a dual purpose. Below is relevant information: 1. Many modern cars are equipped with panoramic sunroofs to enhance natural lighting and broaden the field of vision. However, panoramic sunroofs are not without flaws; they may produce abnormal noises. 2. The sunroof drain hole of the Tiguan is located below the A-pillar. If not cleaned for a long time, it may become clogged, so it is recommended to clean it every six months to effectively prevent blockages. In case the drain hole does get clogged, the owner can use an air gun to blow air into the drain hole, using air pressure to dislodge the obstruction—avoid using high-pressure air. Alternatively, a cleaning method can be employed by using a syringe to inject water into the drain hole, ensuring the drainage pipe remains unclogged. 3. The Tiguan's exterior is highly attractive, with very smooth lines. The large sunroof is one of the main reasons many owners choose to purchase it.
My Tiguan has been running for several years. At first, I didn't understand why the sunroof was leaking, but after checking some materials, I found the drainage hole is located near the A-pillar by the windshield. You need to gently pull open the interior cover of the A-pillar, where there's a small hole—rainwater drains from there. I've dealt with clogs a few times myself; using the soft tube from a bicycle pump to blow through it usually clears the blockage. If left unattended, rainwater can accumulate on the roof, gradually seeping into the car, wetting the headliner and causing mold. Remember, there are similar drainage holes at the C-pillar in the rear seats, but the Tiguan mainly has them at the A-pillar. Regular cleaning is crucial. I check it once every season change to prevent issues before they arise, ensuring the sunroof lasts longer. Don't underestimate this small hole—it's key to the car's leak-proofing.
