Where is the fuel filler cap button located on the Audi A6?

The fuel filler cap switch for the entire Audi A6 series is a sensor lock, which requires manual opening after exiting the vehicle. The fuel filler cap is located on the right side, i.e., the passenger seat direction. When refueling, you need to align the right side with the fuel dispenser. The sensor lock requires the key to be placed near the car, and the engine must be turned off without locking the vehicle to open the fuel filler cap. Steps for refueling the vehicle: Drive the car into the gas station, locate the corresponding fuel filler port, roll down the window, and turn off the engine. Open the fuel filler valve and inform the staff of the appropriate gasoline type. Select the desired amount of fuel to be added. After refueling, ensure the fuel cap is closed before starting the engine. Precautions for refueling: Avoid waiting until the fuel warning light comes on to refuel. Since the fuel pump is located inside the fuel tank, it operates at a high temperature when continuously working, and being immersed in fuel helps cool it effectively. When the fuel warning light comes on, it indicates the fuel level is below the fuel pump. Refueling only when the light is on can shorten the fuel pump's lifespan, and having too little fuel or running out of fuel might even burn out the pump. Try to avoid refueling immediately after the gas station has just received a fuel delivery. The bottom of the fuel tank always contains some water and sediment, which can be stirred up and mixed with the fuel during delivery. Accidentally adding this contaminated fuel can clog the fuel lines and damage the vehicle's engine.

I also struggled with this issue when I drove an Audi A6 before. The fuel filler flap button is actually quite cleverly hidden. In older models, it's usually located in the driver's door storage compartment - just feel along the lower edge of the door panel to find a small button with a fuel tank symbol. For newer Audi models, it's more commonly found among the buttons on the left side of the center console, below the air vents, with an icon resembling a small fuel tank or labeled "fuel cap". If you really can't find it, don't worry - as long as the vehicle is unlocked, you can simply press the fuel filler flap itself to open it, which is a very smart design. By the way, if the fuel filler flap light isn't working, it might be due to a faulty button contact or fuse issue. Since this car has many electronic systems, don't force it open if you encounter difficulties.

A friend asked me the same question when they first got their Audi A6, and I found the placement of the function buttons quite interesting. There's usually a recess on the left door panel near the driver's seat. If you run your fingers along the inner wall closer to the car body, you'll likely find a rectangular button with a fuel tank symbol. If you can't locate it in newer models, check the center console panel near the driver's knee area—some model years have the fuel tank release button placed next to the hazard light switch. Remember to turn off the engine before refueling, as the fuel tank lid won't respond if the car is running—Audi's safety logic makes sense here. Some owners have experienced button jams; a quick fix is to spray some electronic cleaner into the button gaps.

The fuel filler cap button is located in the area just below the left side of the steering wheel, where you can easily feel the soft rubber button with a raised fuel tank symbol. The new Audi design is more concealed, requiring you to find the opening option in the "Vehicle" menu on the central control screen. Important reminder: The vehicle must be unlocked for the button to work; pressing it while the car is locked will be ineffective. Previously, I encountered a button malfunction, which was actually caused by an intermittent fault in the door control unit leading to signal interruption—simply reopening and closing the door fixed it. Remember to regularly clean around the button, as dust buildup can affect the microswitch.
