The fuel tank cap switch of the Golf 7 is located around the A-pillar or B-pillar inside the driver's compartment. Press the fuel tank cap switch to open it. Below are specific details on cleaning the fuel tank: 1. A closed fuel tank accumulates a lot of gum, sludge, particles, and foil. The fuel contains many substances that require regular cleaning to prevent excessive impurities from causing malfunctions. 2. Excessive deposits of impurities and water at the bottom of the fuel tank can block ventilation pipes and fuel lines, creating negative pressure inside the tank. This leads to poor fuel supply, slower throttle response, and reduced vehicle performance. If the fuel level is too low or insufficient at this time, it is crucial to refuel immediately. Do not wait until the warning light comes on. If the fuel pump continues to operate under high temperatures, it can affect its lifespan and, in severe cases, may cause the pump to burn out. 3. For cleaning the fuel tank, you can use the Auto-Fuchs Fuel System Cleaner and Protector. It effectively removes deposits from the fuel tank and fuel lines, as well as cleans injector deposits, restoring and maintaining optimal injection performance. This improves combustion efficiency and saves fuel. In winter, it is advisable to switch to higher-octane gasoline. Due to low-temperature conditions, higher-octane gasoline has a higher ignition point and better ignition capability. Adjust the fuel in the tank according to weather conditions and temperature changes to enhance fuel efficiency.

As a Volkswagen owner, I can relate to this! The fuel filler flap design on the Golf 7 is really clever. There's no separate switch at all - as long as the vehicle is unlocked (either via key or door handle), you can simply press the right side of the fuel flap at the rear, and it pops open with a click. When the car is fully locked, the fuel flap locks automatically too, which provides solid anti-theft protection. There's an emergency release cord hidden behind the right side of the trunk lining, but you'll rarely need it unless you've locked your keys inside. Remember never to force open the fuel flap when the car is locked - those plastic clips can crack easily, and repairs would be painfully expensive.

Last time I drove my friend's Golf 7, I was also confused about refueling. Actually, the operation is super simple: First unlock the entire car (press the key or touch the door handle sensor area), then the fuel tank cap lock will release. Walk to the rear of the car and press the right side of the fuel tank cap near the taillight with your hand. You'll feel a spring mechanism inside - just press and it pops open. If the gas station attendant presses randomly with no response, it's probably because the doors aren't unlocked. Volkswagen's switchless design is quite convenient, though it can confuse beginners. By the way, the fuel tank cap can still be opened after turning off the engine, as long as the car isn't locked.

When I first drove the Golf 7, I was always hesitant about refueling. This generation has eliminated the independent switch! With the car locked, pressing the fuel tank cover won't budge—the anti-theft design is solid. After unlocking the vehicle, press the right curved area of the fuel tank cover directly (avoid pressing the Volkswagen logo spot). You'll need to apply some force to hear the mechanical click as it pops open. If you've modified the center console, you might need to check the settings. In stock condition, unlocking the car doors releases the physical lock on the fuel tank cover. In extreme cases where it won't open, lift the trunk and peel back the right-side interior trim—there's an orange pull cord you can yank hard for emergency access.
