From there, you can insert the fuel pump nozzle into the gas tank and begin refueling your vehicle. When you’re finished fueling, wait five seconds before removing the nozzle from the gas tank so that excess fuel can continue leaking into the tank. Just twist the gas cap back on and click the fuel door into place and congratulations—you’re all done!
Keep in mind that, per the Owner’s Manual, Audi recommends only using “TOP TIER” (or Premium) gasoline in your Audi Q8. If you use the wrong fuel over time, your Q8’s engine performance may be inhibited by combustion residue.
