The fuel tank cap of the Audi A5 is located behind the right-side trim panel in the trunk. Introduction to the fuel tank cap: The fuel tank cap refers to the box on the car used for storing gasoline. It is square in shape, made of stainless steel, and has excellent sealing. There is only a small circular opening, about the size of a bottle cap, which makes it convenient for storage. It is generally placed at the rear of the vehicle. Function of the fuel tank cap: Every car's engine has specific fuel requirements as determined by the manufacturer. Using the wrong fuel can affect the engine, especially if a high-octane fuel engine is filled with low-octane fuel. To prevent the car owner or gas station staff from filling the wrong fuel, the manufacturer specifically labels the required fuel type on the fuel tank cap with a small tag.
