Damage to the engine and fuel system and performance problems caused by using fuels
that are different from those specified above or by using “starting assist fluids” are not the
responsibility of Volkswagen and are not covered under the Emission warranties or any other
Volkswagen Limited Warranty.

The vehicle is warranted to run on diesel fuel containing methyl ester biodiesel in
concentrations of 5 % or less. Never use methyl ester biodiesel in blend levels higher than 5 %
(5 % methyl ester blends are sometimes designated or labeled as B5) unless your vehicle is
registered in Illinois. The properties of methyl ester biodiesel blends in levels greater than 5%
will void coverage for related engine damage under the Emission warranties or any other
Volkswagen Limited Warranty,
unless
your vehicle is registered in Illinois.

Biodiesel especially in concentrations higher than B5, 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 and if not detected and remedied promptly, will ultimately result in engine
damage.
