Using diesel fuel with concentrations of methyl ester biodiesel higher than 20 % (B20), such as B100 is still contrary to the terms of your Emission warranties or any other Volkswagen Limited Warranty and remains strictly prohibited.
Biodiesel blends (up to B20) may be used in your Illinois registered TDI® Clean Diesel vehicle; howev-er, please be aware that biodiesel has characteristics that are different from other kinds of fuel, espe-cially petroleum-based fuels.
Biodiesel can attract water and also deteriorate with age. Small amounts of biodiesel can get into the engine oil, but unlike petroleum diesel, it does not evaporate over time. This can cause the oil level in the engine to rise and can affect the quality of the oil.
x Routinely check the engine oil level. A good time to do this is when you refuel, especially if you regularly do a lot of short distance or stop-and-go driving. This will help you see if the engine oil level is getting higher. (A rising oil level beyond the maximum indicator means an oil change is needed due
to the dilution of the oil in the system; a potential characteristic of biodiesel use) ⇒ page 590, Checking the engine oil level and adding oil.
x If you ever notice that the engine oil level has risen or is above the maximum indicator, contact your authorized Volkswagen dealer, authorized Volkswagen Service Facility or Volkswagen Customer CARE to schedule an oil change – regardless of the time or mileage that has elapsed since you last had an oil change performed.
x Continue to follow the oil change intervals found in the Warranty and Maintenance booklet that came with your vehicle, and use only engine oil that expressly complies with Volkswagen quality standard VW 507 00.
x Refuel only at trusted, commercial fueling stations that are located near main highways. These stations are more likely to have “fresh” biodiesel fuels that have not aged significantly.
x If your vehicle will be in storage (or not driven) for several weeks or months, please completely fill the fuel tank. If possible, fill the tank with Ultra Low Sulfur Diesel fuel [ASTM D-975 standard Grade No. 2-D (S15)].

WARNING
Starting fluids can explode and cause a run-away vehicle condition.
x Never use starting assist fluids.
NOTICE
x The vehicle's diesel engine was designed solely for use with ULSD fuel. For this reason, never use gasoline, heating oil, or other fuels that have not been expressly approved for use with the diesel engine. These fuels contain substances that will severely damage the fuel sys-tem and the engine. Such damage will not be covered by any Volkswagen Limited Warranty.
x If you put any amount of the incorrect fuel in the fuel tank, do not start the engine under any circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance.
x If diesel fuel should get on any rubber hose, it must be wiped off immediately. The same applies if diesel fuel gets onto other parts of the vehicle, especially paint, tires, or a plastic part. Wash the contaminated vehicle parts right away with soap and warm water to help pre-vent leaks and serious damage.
NOTICE
When changing or topping off fluids, make sure that you pour the fluids into the correct reser-voirs. Adding the wrong type of operating fluids will cause serious malfunctions and engine damage!
Fluid leaks are harmful to the environment. Regularly check the ground underneath your vehicle for this reason. If you find spots of oil or other fluids, have your vehicle checked by your authorized Volkswagen dealer or authorized Volkswagen Service Facility. Dispose of leaked operating fluids properly.
Warning light
Engine oil level ranges
⇒ fig. 316 Required action according to the respective engine oil
level:
Range (A) Do not refill oil ⇒ .
Range (B) You may add oil (about 1 pint / 0.5 liters). The oil level
may go into the (A) range, but not above the (A) range.
Range (C)
You must add oil (about 1 quart / 1.0 liter). After adding
oil, make sure that the oil level is about in the middle of
the (B) range.
WARNING
Engine oil can ignite when it touches hot engine parts. This can cause fires, burns, and other severe injuries.
x Never spill oil on the engine. Oil spilled on a cold engine can also cause a fire when the engine warms up.
x Always make certain that you screw the cap of the engine oil filler opening back on tightly after adding oil. This helps prevent engine oil from leaking onto the hot engine when the en-gine is running.
NOTICE
x Do not start the engine if the engine oil level is above range (A). Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Otherwise the catalytic con-verter and engine can be damaged!
x When changing or topping off fluids, make sure that you pour the fluids into the correct reservoirs. Adding the wrong type of operating fluids will cause serious malfunctions and engine damage.
The engine oil level should never be above range (A). Otherwise oil can be drawn in by the crankcase ventilation system and enter the atmosphere via the exhaust system.
