How to Deal with Clogged Sunroof Drainage in a Bora?
2 Answers
You can use an air pump gun, aiming at the drainage holes of the two front drainage pipes inside the sunroof, and use high-pressure airflow to clear the drainage pipes. Here is an introduction to the related content: 1. Sunroof: The left and right sides of the sunroof are two sliding rails that ensure the sunroof slides back and forth. At the front left and right corners of the sliding rails are the drainage holes of the sunroof. 2. Common issues: Clogged or broken drainage pipes can result in water leaking from the sunroof seam and dripping into the interior. If broken, it can also cause water leakage in the car's A-pillar and C-pillar. Another issue is the aging of the sunroof's sealing strip, leading to water leakage from the sunroof.
I've been driving my Volkswagen Bora for several years and often encounter clogged sunroof drains, especially when parked under trees where leaves and dust block the drainage holes. It's not difficult to handle, so don't rush to spend money on repairs. I recommend first finding a safe place to park, turning off the engine, and opening the sunroof to locate the drainage holes—usually small openings at the four corners. Use a small straw or wire to gently poke inside and clear out the debris. If that doesn’t work, you can buy an air pump tool to blow it out, which costs just a few dollars. After cleaning, pour some water to test if the drainage is clear—if water leaks into the car, it can cause mold or damage electronics. It’s best to clean them quarterly as a preventive measure and check before rainy days. A simple DIY can save you hassle and money—don’t wait until the car floods to regret it.
