Where is the blockage causing water leakage into the Volkswagen Bora during rain?
2 Answers
It is due to clogged sunroof drainage tubes. Most vehicles on the market are equipped with sunroofs, which typically have four drainage tubes located at each corner to channel rainwater out of the vehicle through the A-pillars and B-pillars. If these drainage tubes become clogged, rainwater can accumulate in the sunroof, unable to drain, and eventually flow down the headliner into the vehicle's interior, causing water accumulation. Below is an introduction to the new Bora: 1. Exterior Design: The new Bora's design follows the principle of "simplicity," expressing the concept of "less is more" through precision. The precise lines and tight surfaces, combined with exquisite decorations and details, not only reflect Volkswagen's latest design language but also create FAW-Volkswagen's distinctive "X"-shaped sporty DNA. With its dynamic and upright exterior and refined interior design, the Bora offers consumers a visually pleasing and enjoyable experience. 2. Driving and Handling: The new Bora delivers an excellent driving experience with its powerful performance and precise, convenient handling. Equipped with a 1.4TSI engine paired with a DSG dual-clutch seven-speed transmission, along with features like cruise control, cornering light system, and multimedia entertainment system, the new Bora perfectly blends exhilarating driving pleasure with comfortable and relaxing ride quality.
I've been driving my Bora for several years, and the most common leakage issue I encounter is water entering the cabin during rainy days, especially when the drainage holes around the sunroof get clogged. Those tiny holes hidden in corners easily accumulate fallen leaves, mud, or insect remains, causing rainwater to backflow into the car. Last heavy rain, I noticed the carpet was soaked, and upon inspection, found the driver's side drainage hole blocked. I had to use a thin wire to unclog it. If not addressed promptly, water can damage electronic wiring or cause interior mold, leading to unpleasant odors and health issues. I recommend regularly using a soft hose to blow air through the channels for cleaning, especially after parking under trees. This minor issue can be fixed by a professional shop in minutes—don't let a small problem turn into a big hassle.
