What causes water accumulation under the spare tire in the trunk of Golf 7?
2 Answers
The reasons for water accumulation in the spare tire well of Golf 7 are as follows: 1. Leakage caused by damaged or cracked sealing strips. 2. Holes drilled for installing radar or cameras were not properly sealed in time. Here are the solutions: 1. First, drain the water. There is a rubber drain plug at the bottom of the spare tire compartment in the trunk, which can be removed to drain the water; 2. Close the trunk, use a sponge soaked in water to pour water from top to bottom to locate the leakage point, check if the trunk lid is deformed or if the sealing strips are aged; 3. If the body sealing strips are exposed, simply pull them outward slightly; 4. There are drainage holes under the glass sealing strips on the lower side of the trunk lid. Use a sponge soaked in water and a small wooden stick to gently poke under the sealing strips. While pouring water, gently scrape to remove mud inside, as this mud blockage causes the leakage.
As someone who frequently tinkers with cars, I believe the most common cause of water accumulation under the spare tire in the Golf 7's trunk is the aging or damage of the trunk seal. Rainwater or car wash water flows in through gaps in the body and gets trapped in the spare tire well. The seal around the taillight can also be a hazard if it becomes deformed—I've seen many older cars with this issue, as the sealing materials harden over time and lose their effectiveness. The drainage holes at the bottom of the trunk are prone to clogging from leaves and dust, preventing water from draining and forming small pools. A spare tire submerged in water for long periods can rust, and the tool kit may also be affected. It's important to check if the drainage holes are clear before the rainy season. If you find any issues, address them promptly to prevent corrosion of the chassis metal.
