What are the causes of water ingress on the floor of a 2014 Bora's cabin?

Possible causes include rust perforation in the car's chassis, clogged drainage channels, damaged seals, or water accumulation in the sunroof. Here are the detailed explanations: 1. Rust perforation in the chassis: Water can enter through the wheels, so it's necessary to carefully inspect and seal or install protective plates. 2. Clogged drainage channels: The rainwater drainage holes under the front window may be blocked by debris. 3. Damaged seals: During rainy weather, water can seep into the car's floor through the doors. Check the door seals for damage or wear and replace them promptly. 4. Sunroof water accumulation: Prolonged water accumulation in the sunroof can clog the drainage tubes, causing water to flow into the car's floor from the center pillar. Regular inspection and cleaning are essential.

After driving my 2014 Bora for so many years, I've encountered water leakage into the cabin floor. Summarizing the common causes: The rubber seals around the doors can age or harden, reducing their sealing effectiveness—heavy rain then seeps through the gaps and pools on the carpet. If the sunroof's drainage tubes get clogged with leaves or debris, water can't flow properly and may leak into the cabin corners. Frequent use of the AC in summer can lead to cracks or blockages in the condenser drain pipe, causing water to drip directly onto the floor. Small holes in the floorboard or unrepaired damage from past accidents can allow road splash to seep in. If left unaddressed, rust and mold can develop—last time I dealt with it, I even noticed a foul odor. I recommend getting it checked by a professional shop early to avoid impacting the car's lifespan and health.

As someone who often helps friends check their cars, I think there are quite a few reasons for water ingress in the floor of the 2014 Bora. The sealing strips around the door frames have deformed, allowing water to flow in from the outside, and the floor gets noticeably soaked after rain. The sunroof's drainage tubes are designed in the corners and can easily get clogged with debris, causing water to backflow into the car. The air conditioning drain hose may be damaged or disconnected in the wrong position, leading to coolant dripping directly into the cabin, especially when the AC is used frequently in summer. The floorboard can develop micro-holes due to rust, allowing splashing water to enter while driving. Additionally, aging windshield sealant can let water seep through. Don’t underestimate these small issues—accumulated water can soak and ruin the carpet, leading to bacterial growth and unpleasant odors. It’s best to address them promptly to prevent further damage.

I've been using a 2014 Volkswagen Bora for several years. Water entering the cabin is usually caused by damaged door seals or sunroof drainage issues. During rain, water drips from the door gaps onto the carpets, and clogged sunroof drainage pipes cause water to overflow onto the floor. A hole in the AC pipe dripping condensation is also a common cause. When parked outdoors, debris tends to accumulate, making it difficult for rainwater to drain and causing problems. If left untreated, it may lead to mold and rust, affecting the driving environment.
