Where is the fuel tank cap opening switch on the Audi A6?

Audi A6's fuel tank cap switch is located at the lower part of the driver's door, on the left side of the driver's legroom area. The fuel tank cap switch is grouped with the front engine compartment switch - simply press this electronic switch to open the fuel tank cover. For models with keyless entry, keep the key near the vehicle and ensure the engine is off (without locking the car) to open the fuel tank cap. Fuel tank usage precautions are as follows: 1. Don't wait for the low fuel warning light: Check the fuel gauge before driving and calculate whether refueling is needed based on trip distance and gauge readings. Refuel in advance rather than waiting for the warning light. The fuel pump (located inside the tank) generates significant heat during operation and relies on fuel for cooling. When the warning light activates, fuel level has dropped below the pump, which may shorten its lifespan or even cause burnout if repeatedly allowed; 2. Optimal refueling time: Morning or evening is preferable as temperatures are lower and gasoline has lower vaporization points. Gasoline expands with heat and contracts with cold, and is sold by volume. Cooler temperatures yield higher density and greater mass per volume unit, effectively giving more fuel; 3. Avoid full tanks for city driving: There's no need to completely fill the tank for urban commuting. A full tank adds engine load and increases fuel consumption. Since urban areas have abundant gas stations, partial refueling is more practical.
When I first got my Audi A6, I spent ages trying to find where the fuel filler cap was! Finally, an experienced driver friend told me it's on the left rear side of the car, near the driver's side of the rear. Want to open it? No need to get out of the car! Just sit in the driver's seat, feel around the left side near the seat or door panel for a small lever or button, usually marked with a fuel pump icon. Pull or press it, and the cap unlocks. Then, just walk to the rear and lift it open. The most common mistake newbies make is rushing to the back of the car and fumbling around, wasting fuel and getting their hands dirty. Audi's design is quite thoughtful—this method prevents accidental openings while driving. My 2018 model operates this way, but if yours is older or newer, there might be slight differences. It's best to check the user manual first. After refueling, remember to lock it properly and avoid leaving the car under direct sunlight for too long.
