The method to open the BMW fuel tank cap is: press the fuel tank cap switch located next to the driver's leg area. The fuel tank cap refers to the box on the car used to store gasoline. BMW is a German automobile brand, and its models include: BMW 1 Series, BMW 2 Series Gran Tourer, BMW 3 Series, BMW 5 Series, BMW 7 Series, etc. Taking the BMW 5 Series 2021 530Li Leading M Sport Package as an example, its body dimensions are: length 5106 mm, width 1868 mm, height 1500 mm, and the wheelbase is 3105 mm. The BMW 5 Series 2021 530Li Leading M Sport Package is equipped with a 2.0L 252 horsepower L4 engine, with a maximum power of 185 kW and a maximum torque of 350 N·m, matched with an 8-speed automatic transmission.

I remember the last time I drove my friend's BMW 5 Series to refuel, the gas station attendant laughed at me for not being able to open the fuel tank cap for a long time. After the BMW's doors are unlocked, the fuel tank cap is actually in a ready-to-open state. You just need to press the right side of the fuel tank cap with your hand, and it will pop open. The new i3 electric car operates the same way, but for plug-in cars, make sure the charging port is not on the same side first. If there's no response, it might be that the car isn't fully unlocked or there's a central locking system fault. Almost everyone makes this mistake when driving a BMW for the first time, even experienced drivers like me have been tripped up. Never try to pry it open with a key—I've seen people deform the cap, and repairs are a real hassle.

The key to refueling a BMW is remembering to unlock the vehicle. For my old X3, you need to locate the small button with a fuel tank symbol on the driver's door panel – pressing it will make the fuel filler flap pop open with a click. Newer models are simpler: just push the fuel filler flap directly when the car is unlocked. A reminder: for hybrid models where the charging port is adjacent, be careful not to confuse the openings. If it's frozen in winter, don't force it – pour some warm water instead. It's common to see people circling BMWs at gas stations looking for the switch, but the method is actually this straightforward.

The BMW fuel filler cap is designed to be quite concealed. I'm used to unlocking the vehicle, walking to the fuel tank, and pressing the edge of the cover with my thumb until I hear the spring click to open it. Some 3 Series models require locating a dedicated fuel tank button under the center console. If it won't open, it's likely because the car isn't unlocked or the child lock is engaged. I remember one time during snowfall when the cap was frozen shut, and I had to pour warm water on it before it popped open. Gas station attendants often say BMW owners ask about this the most, but in reality, doing it three times forms muscle memory. The key is not to pry at the emblem position—the actual release mechanism is along the right edge.
