The most common reasons why the fuel tank cover of a BMW cannot be opened are "the fuel tank cover is stuck" or "the internal spring is damaged". The fuel tank cover of a BMW needs to be unlocked: The fuel tank cover of a BMW can only be pressed open after it is unlocked. Some car owners go to refuel while sitting in the car without unlocking it, leading to the illusion that the fuel tank cover cannot be opened. Some BMW fuel tank covers are indeed harder to open and require more force. It is best to press the side of the fuel tank cover closer to the rear of the car with your palm and apply more force to open it. Solutions for stuck situations: For a stuck fuel tank cover, you can press the unlock button on the remote key while pressing the fuel tank cover to address the issue. If it is severely stuck, a small wooden piece may be needed to pry it open. The above method works for occasional occurrences, but if the problem happens too frequently, it is best to go to a 4S shop to check and replace the relevant components of the fuel system.
When the fuel tank cap of my BMW 525 wouldn't open that time, it really gave me a headache for a while. There are several common possible causes. First, mechanical components might be stuck, such as excessive dust accumulation causing rust in the fuel cap's lock cylinder or switch - this happens more easily during hot summers, and in my case, pressing it lightly a few times didn't make it pop open. Second, electronic system failures - many BMWs use electric locks, and if the related motor fails, a fuse blows, or there's an issue with the control module, it's common for the cap not to open. When I checked my car, I found it was due to intermittent failure of the central locking key system - the cap would lock when there was no signal. Third, design flaws or wear - aging latches are more common on older vehicles. My first suggestion is to try manually pulling the emergency release, usually a strap located on the side of the trunk that can be yanked open. If that doesn't work, don't force it to avoid damaging more expensive components. I recommend regularly cleaning the locking mechanism to prevent dust buildup. If this problem isn't fixed promptly, it can be extremely embarrassing when queuing at gas stations and waste refueling time. I eventually went to the 4S dealership and got a small replacement part installed, which solved the problem.
