Audi car fuel tank is on the right side. The function of the car fuel tank: In addition to storing fuel, the fuel tank in the hydraulic system also plays roles in heat dissipation, separating air bubbles from the oil, and settling impurities. Many auxiliary components are installed in the fuel tank, such as coolers, heaters, air filters, and liquid level gauges. Fuel tank maintenance: Mainly combined with the first-level maintenance of the car, drain the accumulated water and sediment in the fuel tank, and check for oil leakage at the fuel pipe joints and switches. For fuel tank caps equipped with air valves and steam valves, also check whether their ventilation holes are clear. The filter screen at the fuel filler port should be kept intact to prevent impurities from entering the fuel tank and clogging the fuel lines when refueling. The sealing gasket of the fuel filler cap should also be intact to prevent fuel from overflowing during driving.

Actually, most Audi vehicles have their fuel tanks located on the right side of the car, which is the passenger side. This design is based on left-hand drive configurations for safer and more convenient refueling. I've driven an Audi A4 several times, and when refueling, you need to position the car on the right side so the driver doesn't have to cross the lane, reducing the risk of being hit by other vehicles. If you're unsure about your specific model, check the fuel gauge icon on the dashboard—it usually displays a small arrow indicating which side the tank is on. Alternatively, the simplest method is to step out and take a quick look; the fuel cap is typically located near the door. Some larger SUVs like the Q7 might have slightly different placements, but the vast majority of Audi vehicles follow this design, stemming from European safety standards to avoid conflicts between the fuel nozzle and the driver's seat. In short, when refueling an Audi, just remember the right side, and once you get used to it, you won't go to the wrong side.

The fuel tank of Audi cars is usually positioned on the right side, a common feature among many German brands. This design is primarily for practical reasons: with the driver's seat on the left, placing the fuel tank on the right allows for safer roadside refueling, minimizing the need to step into the traffic lane. Having driven several Audi models like the A3 or Q5, I've noticed the fuel cap is always on the passenger door side; if unsure, you can check below the rearview mirror or along the body lines—the fuel filler is prominently placed. Of course, in right-hand drive countries like the UK, it switches to the left, but in the Chinese market, it's consistently on the right. It's advisable to pay attention to the indicator symbols to avoid wasting time during refueling.

When refueling an Audi, the fuel tank is generally located on the right side, near the door. From the driver's seat on the left, the fuel cap is on the right. For newer models, checking the small arrow next to the fuel pump icon on the dashboard provides a more accurate indication. This design is safer, avoiding the danger of crossing the road.
