Audi Q5: Ethanol fuel (Bio-ethanol)

Audi Q5 Type 8R (2008 - 2017) Owner's Manual / Operating instructions / Fuel and Refueling / Ethanol fuel (Bio-ethanol)

Applies to vehicles: with flexible fuel engine

You can recognize vehicles with a flexible fuel engine by looking at the label on the inside of the fuel filler flap.

Vehicles with flexible fuel engines may be operated with bio-ethanol fuels such as E85 (85% ethanol and 15% gasoline) or with unleaded gasoline (91 AKI/ROZ 95). The vehicle may also be operated with a mixture of these fuels.

Your fuel consumption will increase when using bio-ethanol fuels due to the lower amount of energy contained per unit volume in ethanol.

Warming up the flexible fuel engine in low temperatures

Due to the chemical composition of bio-ethanol, a certain amount of fuel ends up in the engine oil when driving short distances in very low temperatures. This fuel evaporates again when the engine is warmed up.

Please warm up engine.

If the driver message appears in the instrument cluster display, drive with a warm engine to reduce the oil level.

Note

  • Never fill with methanol or with a higher percentage of bio-ethanol than 85% (E85). A higher percentage of bio-ethanol in the fuel can cause damage to the engine or to the fuel system.
  • If you use only E85, it is recommended to fill the fuel tank completely with unleaded premium grade gasoline every 5,000 miles.
  • If you experience starting, rough idle or hesitation driveability problems, fill the fuel tank completely with unleaded premium grade gasoline and drive it normally until the gasoline is used. See your authorized Audi dealer if the problem persists.
  • Inform your authorized Audi dealer that you are operating or have operated the vehicle with E85.
  • Read and follow the information and tips about gasoline

Tips

It may take longer to start the engine when the outside temperature is very cold. If possible, use winterized fuel if temperatures are below freezing.
