Audi Q5: Diesel fuel
Applies to vehicles: with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) No. 2. The ULSD No. 2 meets the ASTM D975.
Diesel fuel with concentrations of biodiesel higher than 5 % such as В11, B20 or B100 are strictly prohibited.
Service station fuel pumps are labeled with the correct fuel information for easy recognition by the user. If the diesel fuel pump is not labeled ask the station operator what fuel is being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the USA and Canada. Be sure to check before traveling to other countries.
ULSD No. 2 can become thicker in very cold temperatures, and this can impair the engine's starting and running. Depending on the season, gas stations provide ULSD No. 2 that flows better in cold temperatures so that you can continue operating your vehicle as usual.
Note
- Your vehicle's diesel engine was designed soley for use with ULSD No. 2. Therefore, never use gasoline, heating oil, other fuels or flow improvers. These contain substances that will severely damage the fuel system and the engine. Such damage will not be covered by your New Vehicle Limited Warranty.
- If you put any amount of incorrect fuel in the fuel tank, do not start the engine under any circumstances. Immediately contact the nearest authorized Audi dealer or authorized Audi Service Facility for assistance. These fuels contain substances that can severely damage the fuel system and the engine if the engine is started.
