Why is there water under the floor mats of a Bora car on rainy days?
2 Answers
If there is water under the floor mats, it indicates that water has entered the vehicle, possibly seeping in through the edges of the door gaps. Solution: If the water ingress is not severe, after cleaning up the accumulated water, open the car windows on sunny days to allow thorough drying. You can park the car in a sunny spot and leave the doors open for drying, or adjust the vehicle's air circulation switch to internal circulation to allow the moisture inside the cabin to be expelled through the air conditioning system. About Floor Covering: The layer beneath the car floor mats is called the floor covering, which is originally installed as a whole in the vehicle. Once dirt or grime gets on it, it can be difficult to clean. Placing a waterproof and easy-to-clean item on top makes cleaning much more convenient. There are two types: hand-sewn and molded floor coverings. A well-made, hand-sewn floor covering can effectively prevent dust and dirt from seeping into the carpet, but its waterproofing capability is somewhat weaker. Molded floor coverings are pressed in one piece with no seams in the middle, offering good leakage protection, but they may not look as aesthetically pleasing when laid over uneven car floors with significant bumps.
I've been driving my Volkswagen Bora for several years, and finding water under the floor mats on rainy days is definitely not a good thing. The most likely causes include aging door seals, clogged drainage holes, or issues with the sunroof seals. Rainwater seeps through gaps and accumulates under the mats. When checking, first look for blocked drainage holes at the bottom of the doors and use a small stick to clear them. Also, pay attention to the sunroof—its drainage channels might be clogged with leaves or debris. Pour some water to test if it flows. If the seals are cracked or deformed, they need to be replaced. If left unresolved, this issue can lead to mold and unpleasant odors in the car, affecting the air conditioning. I recommend taking the time to inspect it thoroughly before the leakage gets worse, as it poses serious safety risks—wet floor mats can cause the brakes to slip.
