If the indicator light appears with a corresponding message, refuel the vehicle.

Tank system: malfunction! Please contact Service

There is a malfunction in the fuel tank system.

Drive to an authorized Audi dealer or authorized Audi Service Facility immediately to have the malfunction corrected.

Fueling procedure

Checking and Filling
Fig. 154 Right rear side of the vehicle: opening the fuel filler door

Checking and Filling
Fig. 155 Fuel filler door with attached fuel cap

The fuel filler door is unlocked or locked by the central locking system.

  • Unlock the vehicle if necessary.
  • Press on the left side of the fuel filler door to open it > fig. 154.
  • Unscrew the tank cap counterclockwise.
  • Place the cap from above on the open fuel filler door > fig. 155.
  • Insert the fuel pump nozzle all the way into the fuel filler neck.
  • Begin fueling. Once the fuel pump nozzle turns off the first time, the fuel tank is full. Do not continue fueling, or else the expansion space in the tank will be filled with fuel.
  • After the fuel pump has switched off, wait five seconds before removing the nozzle to allow the rest of the fuel to finish dripping into the fuel tank.
  • Turn the fuel cap clockwise until it clicks into place.
  • Close the fuel filler door and then press on the left side until it latches.

The correct fuel type for your vehicle can be found on a label located on the inside of the fuel filler door. For additional information on fuel.

For the tank capacity in your vehicle, refer to the Technical Data.

To reduce the risk of fuel leaking out or vapors escaping, make sure that the fuel tank is closed correctly. Otherwise the indicator light will turn on.

WARNING

Improper fueling procedures and improper handling of fuel can lead to explosions, fires, severe burns, and other injuries.

  • Do not smoke. Keep away from open flames.
  • The ignition must be switched off when refueling.
  • Mobile devices, radio devices, and other radio equipment should always be switched off when refueling. Electromagnetic rays could cause sparks and start a fire.
  • If you do not insert the fuel pump nozzle all the way into the filler tube, then fuel can leak out. Spilled fuel can ignite and start a fire.
  • Never get into the vehicle when refueling. If there is an exceptional situation where you must enter the vehicle, close the door and touch a metal surface before touching the fuel pump nozzle again. This will reduce the risk of electrostatic discharge that can cause flying sparks. Sparks can start a fire when refueling.

WARNING

Audi does not recommend transporting fuel containers inside the vehicle. Fuel could leak out of the container and ignite, especially during an accident. This can cause explosions, fires, and injuries.

  • If you must transport fuel in a fuel container, note the following:
    • Always place the fuel container on the ground before filling. Never fill the fuel container with fuel while it is inside or on the vehicle. Electrostatic discharge can occur while refueling and the fuel vapors could ignite.
    • When using fuel containers made of metal, the fuel pump nozzle must always remain in contact with the container to reduce the risk of static charge.
    • Insert the fuel pump nozzle as far as possible into the filler opening while refueling.
    • Follow the applicable legal regulations in the country where you are driving when using, storing and transporting fuel containers.
    • Make sure that the fuel container meets the industry standards, for example ANSI or ASTM F852-86.

Note

  • Remove fuel that has overflowed onto any vehicle components immediately to reduce the risk of damage to the vehicle.
  • Never drive until the fuel tank is completely empty. The irregular supply of fuel that results from that can cause engine misfires.

    Uncombusted fuel may enter the exhaust system and increase the risk of damage to the catalytic converter.

For the sake of the environment

  • Do not overfill the fuel tank, or fuel could leak out when the vehicle is warming up.
  • Fuel should never enter the sewer system or come into contact with the ground.

Tips

The fuel filler door on your vehicle does not lock if you lock the vehicle from the inside using the central locking switch.
