Diesel
Diesel fuel must comply with the European stand-ard EN 590 (in Germany DIN EN 590).
The service intervals are shorter if you use diesel with a high sulphur content =>Booklet Service schedule =>CD. A Volkswagen Commercial Vehicles dealership will be able to tell you which countries have diesel with a high sulphur content.
Where diesel fuel complying with the EN 590 standard is not available, Volkswagen Commercial Vehicles dealerships and filling stations will have information on which fuels do comply with the EN 590 standard.
Do not mix fuel additives (thinners. or similar addi-tives) with diesel.
Winter diesel
When using summer-grade diesel. difficulties may be experienced at temperatures below o•c (+32.F)
because the fuel thickens due to paraffin separa-tion. For this reason winter-grade diesel which can be used at temperatures below -2o•c (·4°F) is available in countries such as Germany during the cold months.
In countries with different climatic conditions the diesel sold generally has different temperature characteristics. Check with a Volkswagen Com-mercial Vehicles dealer or filling stations in the country concerned regarding the type of diesel fuels available.
it is not unusual for a cold diesel engine to be loud-er in cold temperatures that in warm weather. In addition, exhaust emissions may be tinged with blue while the engine starts and reaches operating temperature. The amount of exhaust fumes de-pends on the outside temperature.
CD
• Just one tankful of leaded fuel, or fuel con-taining other metallic additives, can seriously Impair the efficiency of the catalytic converter and can also cause considerable damage to the catalytic converter and engine.
Filter preheater
Diesel vehicles are equipped with a filter pre-heat-er system. This ensures that the fuel system re-mains operational even down to approximately -24•c (-11.F) provided that winter-grade diesel which is safe down to -15•c (+5.F) is used.
However, if the fuel has thickened to such an ex-tent that the engine will not start at temperatures below -24•c (-11.F) simply place the vehicle in a warm garage or workshop for a while.
Supplementary heater
Vehicles fitted with a diesel engine may also be equipped with a fuel-driven supplementary heater. This heater is powered with fuel from the vehicle tank. In this case, odour and water vapour may es-cape from the vehicle, and there may be a greater quantity of smoke. This is quite normal when the system is in use, and does not indicate damage or a fault in the system.
The supplementary heater will be switched off au-tomatically if the level in the fuel tank is low (re-serve level).
A WARNING
Never use a start booster. Start boosters may explode or cause the engine to suddenly run at high revs, which can cause serious Injuries and engine damage.
CD
• Before filling up with diesel, check whether the fuel corresponds to the vehicle's require-ments according to the fuel standard Informa-tion at the pump.
• Only use fuel that complies with the EN 590 standard and has the correct cetane number. Otherwise, the engine and the fuel system can suffer considerable damage. The engine can al-so lose power or fall. ..,.

• Your vehicle is not suitable for use with bio-diesel and must not be filled up or driven with biodiesel. Failure to observe this point can re-sult in damage to the fuel system and engine.
• Some diesel manufacturers blend biodiesel with diesel fuel in compliance with European Standard 590 or an equivalent standard (in Ger-many). Use of this diesel is allowed and will not damage the engine or fuel system.
• The diesel engine has been developed for use with diesel only. For this reason, petrol, heating oil or other unsuitable fuels may not be used. These fuels can cause serious damage to the fuel system and engine.
