Where is the sunroof drain pipe of the Bora located?
4 Answers
The Bora's sunroof has four drainage outlets, one on each side—front, rear, left, and right. The two rear drainage outlets are the easiest to locate, positioned beneath the chassis near the rear wheels, one on each side. The front drainage outlets are inside the A-pillars on both sides, where water typically drains directly through the gaps in the car. Below is an introduction to car sunroofs: 1. A car sunroof is installed on the roof and effectively promotes air circulation inside the vehicle, increasing the intake of fresh air, providing owners with a healthy and comfortable experience. Additionally, car sunroofs can broaden the field of vision and are often used for mobile photography and videography needs. 2. Car sunroofs can be broadly categorized into: sliding-out, built-in, built-in flip-out, panoramic, and curtain-style sunroofs. They are mainly installed on commercial SUVs, sedans, and other vehicle models. 3. Precautions for sunroof usage: (1) Pay attention to the condition of the sunroof rails. (2) Avoid using the sunroof too frequently. (3) Do not open the sunroof immediately when the car is cold in winter. (4) Try to avoid opening the sunroof on bumpy roads. 4. Sunroofs are relatively delicate features. In addition to regular cleaning and lubrication of the sunroof rails, we should also use them gently to ensure they serve us for a longer time.
Last time I cleaned the drainage pipes of my Bora's sunroof, I realized how well-hidden this system is. There are four outlets in total—two in the front located behind the side mirrors on the chassis, where you can feel the rubber nozzle with your fingernail, and the rear pipes run along the C-pillars to the inner side of the rear wheel arches. The key is to regularly clean the roof drainage channels using a thin, flexible hose. Once, leaves completely blocked it, flooding the passenger footwell and costing over 800 yuan to fix. Now, I make sure to check every spring, especially for cars parked under trees, as fruit pits can easily clog the drainage pipes.
The most profound realization from driving the Bora over the years: nine out of ten sunroof leaks are caused by drainage pipes. The pipes are hidden behind the A-pillar and C-pillar trim panels, like little transparent snakes running downward. The front pipe outlet is at the corner of the front wheel fender on the chassis, while the rear one hides inside the rear bumper. A mechanic taught me that using an air compressor to blow through them is the most effective method—just pour two cups of water to test the flow rate and check for blockages. Remember to inspect them before the rainy season—last time, after a heavy downpour, water seeped through the roof, and upon disassembly, I found a loose pipe joint, which was a hassle to fix.
Just finished helping a friend fix the sunroof leak on his Volkswagen Bora. The upper ends of the drainage tubes are located at the four corners of the sunroof tracks - lifting the rubber seals reveals coin-sized water inlets. The key points are the outlet positions: there are duckbill valves behind the front wheel fenders and curved pipe outlets at the rear wheel chassis. When encountering poor drainage flow, avoid poking forcefully with wire - I directly used a syringe to inject soapy water combined with vacuum suction for better results. Pay special attention to aged vehicles where pipe deterioration and hardened rubber can cause joint cracks and water seepage.
