What causes water ingress in the Polo's cabin during rain?

Water ingress in the Polo's cabin during rain may be due to a malfunctioning sunroof. Below are the methods for dealing with cabin water ingress: Removing accumulated water inside the vehicle: When water enters the cabin, the repair process mainly involves removing the accumulated water. There are several rubber sealing plugs located at the lower part of the vehicle chassis. Opening these plugs allows the water inside the cabin to drain out. However, since the floor mat material inside the vehicle is highly absorbent, it should be removed and placed in a spacious area to facilitate water evaporation. Drying and cleaning: Water in the cabin often contains dirt and mud. Once the weather clears, removable interior items such as floor mats and seat covers should be taken out for drying and cleaning. Less dirty carpets can be directly treated with a vacuum cleaner. For dirtier carpets, specialized cleaning agents must be used.
