I’m having a hard time getting my new car’s gas tank to open. How do you open the gas tank on a BMW 320i?

You can open the gas tank on any BMW 3 Series—including the 320i—by pressing down on the fuel-filler door. Just make sure your vehicle is parked, the engine is off, and your doors are unlocked. Otherwise, the latch may not release.
That’s because BMW gas tanks are designed to unlock only under safe conditions like the ones listed above. Not only does it ensure safe fueling, but also helps prevent anyone else from meddling with your gas tank or siphoning the gas.
Pressing once on the fuel-filler door should be all it takes to get it to pop open. From there, you should be able to pull the door back and unscrew the cap for easy fueling. But if that doesn’t work, it could be that the latch itself is stuck.
In that case, opening the fuel tank is trickier—you’ll have to release the latch manually by pulling on a tether located behind the battery tray in your BMW’s trunk. You may be able to find instructions on how to manually open your gas tank in your car’s owner’s manual. If not, you should bring your BMW to a mechanic or dealership for professional assistance.
