What are the reasons for water leakage in the FAW-Volkswagen Bora cabin?
2 Answers
The reasons for water leakage in the FAW-Volkswagen Bora cabin are as follows: 1. Clogged sunroof drainage holes: Sunroof drainage holes are easily blocked by fallen leaves and dust. Once clogged, rainwater cannot drain in time during rainfall and may seep into the cabin. 2. Aging sunroof rubber seal: Rubber components harden and deteriorate over time. When the sunroof rubber seal ages, its sealing performance decreases, leading to leaks during rain. Additionally, using high-pressure water guns or strong acidic/alkaline cleaners during sunroof maintenance can deform or accelerate the aging of the rubber seal. 3. Clogged air conditioning drain hole: During operation, the car's air conditioning evaporator produces condensation. If the drain hole is blocked, condensation water may leak from the passenger side. 4. Poor door sealing: Doors are equipped with sealing strips. If improperly installed or aged/hardened, the door's sealing performance decreases, allowing water ingress during rain or when driving through flooded areas. 5. Clogged door drainage holes: Due to their low position, door drainage holes are prone to mud blockage. If rainwater accumulates in the door and cannot drain, it may seep into the cabin.
My own Bora also experienced cabin water leakage, mainly caused by clogged sunroof drainage holes. During the rainy season back then, water seeped in from the corners of the sunroof, soaking the carpets completely. Later, I discovered that aging door seals were also an issue—over time, the rubber strips deformed and leaked. Another time, the air conditioning drain pipe was blocked, causing condensation water to drain directly into the cabin. Cracks in the windshield sealant should also be noted, as they can lead to water seepage during heavy rain. I recommend first checking the sunroof drainage holes and using a thin wire to clear the drainage pipes. If it's a door seal issue, replacing the rubber strips can solve the problem. It's best to address it promptly, otherwise, water damage to the electrical circuits could be troublesome.
