Where does water accumulate after the sunroof of a Bora car leaks?

After the sunroof of a Bora car leaks, there is no dedicated water storage area. It is necessary to drain the water promptly; otherwise, it may cause water accumulation and affect the normal use of the car. The Bora sunroof has four drainage outlets. The drainage outlet under the door: If the drainage outlet under the door is blocked, rainwater inside the door cannot drain out, which may lead to corrosion and rust of the door over time. It may also cause a short circuit in the vehicle's electrical system and even a fire. Regular maintenance to ensure the door drainage holes are clear is essential. The sunroof drainage outlet:
Last year, the sunroof of my Bora got clogged, and water directly flooded into the car. At the time, I noticed the area around the roof handles was damp, and only after removing the A-pillar trim did I discover that the drainage pipe joint had come loose. The water mainly accumulated in four places: the sunroof frame's drainage channel was filled to the brim like a small ditch, water was cascading down inside the A-pillar cavity, and the most troublesome part was the carpet's underlying sponge, which absorbed water and became heavy. Even under the passenger foot mat, you could hear the sound of water when stepping on it. This water couldn’t evaporate naturally at all. I spent the whole night using bath towels to soak up three basins of water, and later had to remove the seats and lift the carpet to dry it out for three full days. During that time, the musty smell was so strong it gave me a headache.
The repair shop mechanic told me that the Leakage in the Volkswagen Bora's sunroof is mostly hidden. In the cars they've encountered, water mainly accumulates in the metal sandwich layer of the roof, just like the filling in a sandwich, requiring the removal of the ceiling for cleaning. Secondly, the cavity inside the door frame's anti-collision beam can also turn into a water tank, and they've used an air gun to blow out small puddles. The most critical issue is the wiring channel under the dashboard; cars that have been waterlogged often end up with burnt-out air conditioning modules. Last month, while helping a friend deal with a leakage, when we lifted the passenger side carpet, we found the sponge securing the wiring harness soaked with water, squeezing it felt like a wet sponge. Water accumulation in such areas can take up to half a year to dry out completely.
