How to open the fuel tank cap of a BMW 5 Series?

[LeEvangeline]

The method to open the fuel tank cap of a BMW 5 Series is: 1. Press the fuel tank cap switch on the driver's door; 2. Press the fuel tank cap located above the left wheel on the body. Taking the 2021 BMW 530Li Leading Edition as an example, its body dimensions are: length 5106mm, width 1868mm, height 1500mm, wheelbase 3105mm, fuel tank capacity 68 liters, and curb weight 1710kg. The 2021 BMW 530Li Leading Edition is equipped with a 2.0L turbocharged engine, with a maximum horsepower of 252PS, maximum power of 185kW, and maximum torque of 350Nm.

Every time I drive my BMW 5 Series to refuel, I find the method to unlock the fuel tank cap is very simple. After sitting in the driver's seat, first locate a small lever or button with a fuel pump icon under the dashboard near the left leg, then gently pull or press it to hear a slight unlocking sound. At this point, the fuel tank cap outside the car has loosened. Simply walk to the right side of the car, press the cap, and it will pop open. After refueling, press it again to close. BMW's design is very thoughtful—the fuel tank cap automatically locks to prevent fuel leakage and is secured by the central locking system to ensure safety. The key point is that the car doors must be unlocked to operate this lever; otherwise, the cap won’t pop open. So, I always remember to press the key unlock button or enter the car and open the door first. This system is highly reliable in daily use, reducing the hassle of manual unlocking.

As a 5 Series owner for several years, I'm quite familiar with the fuel filler flap operation. After entering the car, the first thing is to look down near your left foot - there's a plastic lever with a fuel tank symbol. A gentle pull will unlock the fuel filler neck. Then exit the vehicle and press the fuel door at its location to open the flap. After refueling, simply push it back - it will click into place automatically. I remember once being in a hurry to refuel and couldn't pull the lever no matter how hard I tried, only to realize later that the central locking system was still engaged. Now I always press the unlock button after entering. BMW's anti-theft design is effective, but be careful not to force the lever to avoid damaging components.

When working on cars, I've handled quite a few BMW 5 Series models. Their fuel filler cap operation is mostly standardized: locate the small lever marked with a fuel pump icon near the left footwell on the driver's side, pull it to unlock – no key needed to open the cap. Press the exterior to open it. The key point is this system links to the door locks; when doors are locked, the cap also secures to prevent accidents. Modern models like the G30 even support button operation for added convenience. Occasional jamming might occur due to dust accumulation in wiring or spring fatigue – manually pressing a few times or checking for loose connectors usually restores function.
