How to Fix a Polo Trunk Lock Malfunction by Yourself?
2 Answers
The methods to fix a Polo trunk lock malfunction by yourself are: 1. Lubricate and adjust the trunk; 2. Clean the trunk's card slot; 3. Replace the spring rod with moderate hardness; 4. Check if there is any fault in the trunk's control circuit; 5. Replace the trunk's hydraulic support rod. The maintenance methods for the trunk are: 1. Use a brush to clean dirt when washing, including the edges and grooves of the trunk, and perform odor treatment after cleaning; 2. Place items in an organized manner using separate cargo bags; 3. Lay a trunk mat to prevent dirt or liquids from entering the trunk and eroding the trunk surface, while also preventing items inside the trunk from sliding, reducing the possibility of contamination or damage.
Last time I encountered the issue of my Polo's trunk not opening, I spent quite some time tinkering with it myself. The first step was to check if the lock was jammed—I sprayed some WD-40 on the lock cylinder and latch, then tested the trunk by opening and closing it several times. If it was still stuck, I inspected the lock mechanism for any deformation or broken parts. For electric models, I removed the trunk trim to check for loose wiring connections and tried unplugging and re-plugging the connectors to clean any rust spots. If all else failed, I might have needed to replace the entire lock assembly—buying an original part online costs around a hundred bucks. When installing it myself, I made sure not to be too rough to avoid damaging the car's paint. After fixing it, I lubricated the lock every time I washed the car to prevent future headaches. The job took some time but saved money and gave me peace of mind, avoiding the hassle and expense of a trip to the repair shop.
