What is the reason why the fuel tank cap of a Polo car cannot be opened?

The fuel tank cap of a Polo car cannot be opened due to a damaged motor. The methods to open the fuel tank cap and the maintenance methods for the fuel tank are as follows: Method to open the fuel tank cap: If the fuel tank cap cannot be opened, you can start from the trunk. First, remove the lining panel covering the fuel tank in the trunk. The lining panel is usually fixed with some plastic clips and can be easily pried open with a screwdriver. After removing the lining panel, you can see the locking mechanism of the fuel tank cap and the pull cable for remote operation. Simply pull the cable, and the fuel tank cap can be opened. If this does not work, you can press the movable part of the locking mechanism while continuously pulling the cable, and the fuel tank cap will open easily. Some car models have a dedicated switch on the locking mechanism; pressing this switch will open the fuel tank cap. Fuel tank maintenance methods: Drain accumulated water and sediment from the fuel tank, and check for oil leakage at the joints of the oil pipes and switches. For fuel tank caps equipped with air valves and steam valves, also check if the ventilation holes are clear. The filter screen at the fuel filler port should remain intact to prevent impurities from entering the fuel tank during refueling and clogging the fuel lines. The sealing gasket of the fuel filler cap should also be intact to prevent fuel from spilling out while driving.
I also encountered the issue of a fuel tank cap not opening when driving a Polo before. Later, I found out it might be due to a minor glitch in the central locking system. The Polo's fuel tank cap is usually linked to the car's lock mechanism, so if the central lock doesn't respond, the fuel tank cap won't open either. Another common issue is mechanical jamming, such as aging seals or dust accumulation causing the cap to get stuck. Personally, I've tried repeatedly pressing the unlock button on the key fob, which occasionally solves the problem. Additionally, check if the fuel tank cap's release cable is loose or rusted—older models are more prone to this issue. Extremely cold or humid weather can also cause metal components to contract or become sticky; a light spray of lubricant on the latch area might loosen it up. In any case, if the cap doesn't open, avoid forcing it to prevent part damage. It's advisable to first inspect the locking system and, if that doesn't work, promptly visit a repair shop to adjust the lock cylinder or replace related components. To prevent such faults, try to avoid parking in dusty areas and regularly clean the fuel tank opening.
