Neve r use leaded gasoline! Leaded gasoline will severely damage your vehicle's cat a lytic verter.
MetJ1anol-blended fuel s that do not meet the criteria listed above may cause corrosion, and damage to pla sti c and rubber parts in the fu el system.
Never use fuels tJ1at contain lead or oth e r metals (chec k listin g on the fu el pump). Even lead replacement petrol fu els) contain metalli c additives in high concentrations. They can damage the engin e.
Do not use fuel s that fail to meet the criteria
above, or with contents that cannot be identi.fied.
If you cannot tell w hether a particular fuel

Note
The vehicl e's diesel engine was designed sole ly
for use with ULSD fuel. For this reason , nev er use gaso line, heating oil, or other unsuitable fuels. The properties of these fuels may cause serious damage to the fuel system and to the engin e. Such damage will not be covered by any Volkswagen

The vehicle was designed to run on diesel with blend leve ls up to and including 5% methyl ester biodi esel. Never use methyl ester biodiesel in
blend lev els hi gher than 5% (5% methyl est er
blends are sometime s designated or labeled as
B5). The propertie s of methyl ester biodiesel
blend s in leve ls greater than 5% may cause riou s damage to the fuel injection system and to the engine. This co uld lead to expensive repairs that will not b e cove red any Volkswagen Limited
