What are the reasons for water ingress on the floor of the 2014 Bora's cabin?

Possible causes include rust perforation in the car's chassis, clogged drainage channels, damaged sealing strips, or water accumulation in the sunroof. Below are the detailed explanations: 1. Rust perforation in the chassis: Water can enter through the wheels, so it's necessary to thoroughly inspect and seal or install protective liners. 2. Clogged drainage channels: The rainwater drainage holes under the front window's drainage channel may be blocked by debris. 3. Damaged sealing strips: During rainy weather, water can enter the car floor through the doors. Check if the door sealing strips are damaged or ineffective and replace them promptly.
My 2014 Bora had water leakage in the cabin before, and the dampness drove me crazy. There are multiple main causes: the sunroof drain pipes are prone to clogging—when blocked by leaves and dust, rainwater pours down from the headliner, soaking the floor; the door seals age and deform, allowing water to seep in during car washes or rain; if the AC drain pipe clogs, condensed water backflows and drips into the cabin; gaps in body panel welds or poorly applied sealant let rainwater seep through; and aging windshield seals allow water to flow directly into the footwell area. If you notice water intrusion, check these points immediately. In my case, it was a clogged sunroof pipe—clearing it fixed the issue. Delaying repairs risks floor rust and electrical shorts, which are far worse. I recommend regular maintenance of the sunroof and door seals to prevent problems proactively.
As a technician who has repaired many Bora vehicles, there are several common sources of water ingress in the cabin. The most frequent issue is clogged sunroof drainage systems, where water overflows from the headliner onto the floor. Worn or deformed door sealing strips can also create gaps that allow water leakage. Blocked air conditioning evaporator drain pipes may cause water to backflow. Poor welding of body floor seams can lead to water seepage during rainy seasons, and failed windshield installation adhesive seals are another culprit. The inspection sequence should start by checking if the sunroof drainage is clear, using a water hose during car washing to test for leaks. Next, examine the elasticity and connection of door seals, and ensure the air conditioning drain pipe is cleaned. If not repaired promptly, accumulated water can corrode metal components and affect electronic elements of the braking system. Regularly using a vacuum cleaner to clear drainage holes can save money and hassle.
Buddy, I've encountered the issue of water leakage in the cabin of a 2014 Volkswagen Bora. It's mostly caused by clogged sunroof drains, where rainwater accumulates on the roof and leaks down; aging or damaged door seals that let water seep in during heavy rain; or blocked AC drain outlets causing water backflow or leaks at body panel joints. If you notice water stains, promptly check the sunroof drain holes for leaf blockages and inspect the door seals for cracks. After repairs, remember to clean the drainage paths annually to prevent mold odors and safety hazards—simple maintenance can prevent bigger issues. Don't wait until it's severely damaged to take action, as the repair costs will be much higher then.
