The reasons for water leakage in the trunk of a Volkswagen Santana include: aging or damage to the trunk seal; cracks at the welding joints of the tail light housing; detachment of the sunroof drainage pipe; and damage to the paint sealant at the roof joints. Below is a detailed introduction to the Santana: 1. Interior: Equipped with features such as ESP, cruise control, and leather seats. Some manual transmission models also come with automatic air conditioning. 2. Powertrain: Powered by EA211 engines with displacements of 1.4L and 1.6L. The 1.4L engine delivers a maximum power of 66kW, while the 1.6L engine produces a maximum power of 81kW.
Trunk leaks are a common issue, mostly seen in old Santanas where the sealing strips age, crack, and lose elasticity. Over time, the rubber deteriorates, causing water to seep through the seams. Clogged drainage holes are also frequent culprits—parking under trees allows mud and leaves to accumulate, blocking water drainage and causing backflow. Damaged or loose sealant around the taillights can create gaps, especially noticeable during car washes. Another root cause is rust and corrosion at the body panel seams, allowing rainwater to seep inside. I recommend a simple DIY check: use a high-pressure hose to spray the trunk and identify leak points, or temporarily seal them with tape. Visit a professional shop promptly to replace the seals and clear drainage holes—don’t let a minor issue escalate and damage the interior.
