What are the reasons for water ingress in the Golf cabin?

It may be due to aging of the car's sealing strips, improper sealing of the car doors, or deformation. It is best to conduct a comprehensive inspection of the vehicle. Below are the relevant explanations: 1. Car drainage outlets: There are generally four drainage outlets on a car, two in the front and two in the back. The front drainage outlets are for sunroof drainage, while the rear ones are for draining water flowing on the car. 2. Reasons for seal aging: The rubber seals on the doors will age after prolonged use. Since the seals are made of rubber products, they may crack or harden over time, leading to water ingress during rainy weather. If leakage occurs, the seals can be replaced or sealed with adhesive.
I've encountered this situation before. Water leakage in the Golf's cabin is mainly caused by clogged sunroof drainage holes, allowing water to flow from the sunroof into the car. Additionally, aging or damaged door seal strips can also cause leaks, especially during heavy rain when water easily seeps in. If the drainage pipe of the air conditioning system's evaporator gets blocked, condensed water can accumulate on the cabin floor. These are common issues, and I recommend regularly cleaning the sunroof tracks, checking all sealing components before the rainy season each year, and preventing leaves or dirt from clogging the drainage channels. If not addressed promptly, a wet cabin can lead to mold growth, damaging electronic components or seats, which is really troublesome. I personally experienced soggy floor mats and ended up spending money on repairs, so developing good maintenance habits can save a lot of hassle. In short, start by checking the simple drainage holes first.
