body.  
Safety information on using fuel  
WARNING  
Incorrect handling of fuel can cause explosions, fire, serious burns and other injuries.  
Switch off the engine, the ignition, the auxiliary heater, your mobile phone and other radio equipment before  
refuelling.  
Avoid electrostatic discharges by not entering the vehicle during refuelling.  
Make sure that the tank cap is closed properly and no fuel can escape.  
Observe the applicable safety instructions and local regulations on handling fuel.  
WARNING  
Incorrect refuelling can lead to fire, serious injuries and vehicle damage.  
Use only fuels that have been approved for the vehicle.  
Do not use fuels that contain metals and use only manufacturer-approved additives in the approved quantity.  
Immediately remove any fuel that is spilled from all vehicle components.  
CAUTION  
Fuel may run out of the spare fuel canister. This could cause fire and injuries.  
Do not carry a fuel canister in the vehicle.  
Fuels can pollute the environment. Collect any service fluids that escape or are spilled and dispose of them  
correctly.

Identification of fuels and fuels standards  
Fig. 1 In the tank flap: fuel information label.  
Fuel information label  
Different engines require different fuels. There is a factory-fitted fuel information sticker in the tank flap that  
indicates the required fuel type for the vehicle → Fig. 1.  
The designation and the framework indicate, which fuels are suitable for the vehicle. This is a minimum requirement.  
Other fuels must not be used for the vehicle →  
.
Fuel standards  
The fuel being filled needs to comply with one of the following standards→  
.
Where fuel complying with the specified standards is not available, a qualified workshop will have information on  
which available fuels are suitable for the vehicle.  
Petrol  
Petrol fuels withEthanol content. The number specifies the maximum ethanol content in the petrol, e.g. E5 for  
a maximum of 5% ethanol.  
Fuel standard  
EN 228.  
Diesel  
Diesel fuels with Biodiesel content. The number indicates the maximum biodiesel content of the diesel, e.g. B7  
for maximum 7% biodiesel.  
Fuel standard  
EN 590.  
DIN EN 590.  
453  
Synthetic diesels  
Synthetic diesels.  
XTL fuels are diesel fuels that are manufactured synthetically. These synthetic diesel fuels includeGTL  
(Gas To Liquid), BTL (Biomass To Liquid) and HVO (Hydrotreated Vegetable Oils), where natural gas or biomass are  
used as the initial energy carrier.  
Fuel standard  
EN 15940.  
DIN EN 15940.  
NOTICE  
Using fuel that does not comply with these standards and is not approved may reduce performance and cause  
damage to the engine and fuel system.  
Before refuelling, check whether the fuel identification specified on the pump meets the vehicle's requirements.  
Use only fuels that meet the required standards and labelling in order to prevent damage to the fuel system and  
engine failure.  
Petrol  
The petrol types differ in their research octane number(RON). The vehicle may be filled with petrol that has a higher  
RON than the engine requires. However, this does not provide any advantage in terms of fuel consumption or engine  
output.  
The fuel information label on the inside of the tank flap may show several types of petrol, e.g9. 5/92/97/93 RON. The  
highlighted petrol grades, 95/92 in the example, are the preferred petrol grades for the vehicle. The other listed  
petrol grades may only be filled if the highlighted ones are not available. In this case, choose the petrol grade with  
the higher RON, e.g. 97 instead of 93 RON.  
Fill vehicles with a petrol engine only with unleaded petrol or petrol with a maximum ethanol content of 10 %(E10)  
.
The fuel quality affects the running properties, performance and service life of the engine. Refuel with fuel that  
already contains suitable additives →  
.
NOTICE  
Errors during refuelling or unsuitable fuel additives may cause damage to the vehicle.  
Before refuelling, check whether the fuel standard specified on the pump meets the vehicle's requirements.  
Use only service additives that have been approved by Volkswagen Commercial Vehicles in the approved quantity.  
Refuel only with petrol that has the specified or a higher Research Octane Number(RON). If, in an emergency, you  
have to use petrol with an octane number lower than the recommended number, drive at medium engine speeds  
and avoid high engine loading. Avoid high engine speeds and heavy engine loads. Refuel with petrol with the  
correct octane number as soon as possible.  
454  
Diesel  
Always refuel diesel with a low sulphur content or with sulphur-free diesel in order to avoid damage to the engine  
and particulate filter.  
Fill vehicles with a diesel engine only with diesel or diesel with a maximum RME fuel content of 7 %→  
.
If you use diesel with a high sulphur content, the service intervals are shorter. Suitably qualified workshops can  
provide information on countries that use diesel with a high sulphur content.  
The fuel quality affects the running properties, performance and service life of the engine. Refuel with fuel that  
already contains suitable additives →  
.
Winter-grade diesel fuel and filter preheater system  
During the winter season, you have to use diesel with improved flow characteristics under cold conditions(winter  
diesel). You can avoid operational faults by refuelling winter diesel. Winter diesel is offered at filling stations during  
the winter season.  
There may be different classes of cold depending on the climate and time in the national fuel standards.  
Diesel vehicles are equipped with a filter preheater system. The cold flow characteristic of the diesel is ensured while  
driving by the filter pre-heating function. Information on the cold properties of diesel is provided by the filling  
stations of the respective country, Volkswagen Commercial Vehicles dealerships or qualified workshops.  
Volkswagen Commercial Vehicles recommends leaving the vehicle somewhere where it is sheltered from the  
weather, e.g. in a garage, to ensure that it can still be started even at very low ambient temperatures.  
Misfuelling prevention device  
The tank filler neck in diesel vehicles may be fitted with a misfuelling prevention device. This is intended to help  
ensure that the vehicle is refuelled only using diesel filler nozzles.  
If you are unable to insert the fuel nozzle into the tank filler neck properly, first check whether you are using a diesel  
pump nozzle. Once you have ascertained that you are using the correct filler nozzle, turn the diesel filler nozzle back  
and forth while applying light pressure. This can open the misfuelling prevention device and make it possible to refuel  
the vehicle. If the misfuelling prevention device is still closed, contact an authorised workshop and have the system  
checked.  
The misfuelling prevention device may not open if you have to refuel the vehicle using a spare fuel canister in an  
emergency.  
In order to still fill the tank with fuel, pour thediesel into the tank extremely slowly in very small quantities. Use a  
suitable adapter for the spare fuel canister to make refuelling easier. The relevant adapters are available from a  
suitably qualified workshop.  
WARNING  
Incorrect refuelling can lead to fire, serious injuries and vehicle damage.  
Before refuelling, check whether the fuel standard specified on the pump meets the vehicle's requirements.  
Do not refuel with pure RME fuel, petrol, fuel oil or other unsuitable fuels.  
Use only service additives that have been approved by Volkswagen Commercial Vehicles in the approved quantity.  
At cold temperatures, louder noises may occur in the diesel engine and the exhaust gas may be tinged  
blue.

Refuelling  
Fig. 1 On the left-hand side of the vehicle: tank flap with  
open tank cap.  
Refuelling process  
You must refuel the vehicle only with the fuel grades specified on the fuel information label in the tank flap  
(→ Identification of fuels).  
1. Close the left sliding door.  
2. Open the tank flap.  
Vehicles with tank flap collision protection:You will hear a clicking sound when the tank flap is opened. This is  
normal and does not indicate a technical problem. The left sliding door is blocked and cannot be opened when  
the fuel filler flap is open. You can open the sliding door again only when the tank flap has been closed.  
Vehicles without tank flap collision protection:Keep the left sliding door closed during refuelling→  
3. Turn the tank cap to remove it and place it in the holder in the tank flap→ Fig. 1.  
4. Hold the filler nozzle so that the handle is facing down in order to ensure optimum filling.  
The fuel tank is full when the properly operated automatic filler nozzle clicks off for the first time→  
5. Turn the tank cap onto the tank filler neck until it clicks into place.  
.
.
6. Close the tank flap.  
WARNING  
Overfilling the fuel tank may cause the fuel to splash out and overflow. This can cause fires, explosions and serious  
injuries.  
Do not continue refuelling after the filler nozzle switches off for the first time.  
CAUTION  
Opening the sliding door on the left-hand side can cause injuries and damage the vehicle.  
Make sure that the tank flap is closed before opening the sliding door.  
456  
Diesel ageing  
Compared to other fuel types, fuels with a high biodiesel content(> 7 vol.%) may have a higher water absorption  
capacity and tend to age (decompose) more rapidly due to lower oxidation resistance. Water and dirt promote  
microbial activity and accelerate fuel ageing, which can lead to the vehicle's fuel system being damaged.  
Perform the following actions to avoid damaging the vehicle’s fuel system.  
If the vehicle is stationaryas from two weeks:  
1. Fill fuel tank to maximum level.  
2. Start the vehicle at least once a week for around five minutes.  
If the vehicle is stationaryas from 45 days:  
1. Diesel fuel in the fuel tank may have aged→  
.
2. You must replace the diesel in the fuel tank and fuel filter before starting the engine again. The diesel and the  
fuel filter should be changed by a suitably qualified workshop.  
NOTICE  
If the diesel fuel contains water or is decomposed and the engine is started, this can cause serious damage to the  
fuel system.  
If water has settled in the fuel filter, it must always be drained.  
Always fill up with high-quality diesel fuel that meets the required specifications.  
Water and diesel fuel must never be disposed of in gardens, forests, sewage systems, roads or paths, rivers  
or running waters. In order to avoid environmental pollution, disposal must be carried out by a suitably  
qualified workshop.  
457  
Troubleshooting  
Irregular engine running and malfunctions  
Irregular engine running or faults when driving may be a sign of poor fuel quality:  
1. Reduce speed immediately.  
2. Drive to the nearest qualified workshop at medium engine speeds and low loads on the engine.  
3. If the symptoms occur immediately after refuelling, switch off the engine straightaway to avoid any subsequent  
damage.  
4. Seek assistance from a suitably qualified workshop.  
You can expect engine faults and increased fuel consumption if the indicator lamp is lit  
up.  
458  
Introduction  
Checklist  
The components relevant to emission control reduce harmful emissions. Observe the following points to ensure that  
the components relevant to emission control work in the long term:  
Never allow the fuel tank to run completely dry.  
Only refuel with fuels that are suitable for the vehicle (→ Identification of fuels).  
Only use engine oil suitable for the vehicle (→ Engine oil).  
Do not refill too much engine oil (→ Engine oil).  
Do not tow-start the vehicle. Use jump leads (→ Jump starting).  
If you notice misfiring, loss of power or uneven running when driving, reduce speed immediately and have the vehicle  
checked by a suitably qualified workshop. If this happens, unburnt fuel can enter the exhaust system and escape into  
the atmosphere. The components relevant to emission control can also be damaged by overheating.  
WARNING  
Engine emissions contain carbon monoxide that can cause people to lose consciousness and can also cause death.  
Do not allow the engine to run in enclosed spaces.  
Never start the engine in enclosed spaces.  
Do not leave the vehicle unattended if the engine is running.  
WARNING  
The components of the exhaust system become very hot. This can cause fires.  
Park the vehicle so that no part of the exhaust system can come into contact with any inflammable material  
underneath the vehicle, e.g. dry grass.  
Do not apply additional underseal or anti-corrosion coatings to the exhaust pipes, catalytic converters, particulate  
filters or the heat shields.  
The emissions may have a sulphur-like smell even if the emission purification system is working  
properly.

AdBlue®  
®
The SCR catalytic converter uses AdBlue® urea solution to convert nitrogen oxides into nitrogen and water. AdBlue  
is a registered trademark and is also known as AUS32 or DEF (Diesel Exhaust Fluid).  
Legal information  
®
No technical modifications which affect emission control by AdBlue may be made to the emission control system.  
®
Only operation with AdBlue that complies with ISO-22241-1 is approved by the manufacturer and corresponds to  
the Certificate of Conformity issued for this vehicle type.  
®
Operating the vehicle without AdBlue that complies with ISO-22241-1 may be a criminal offence.  
If the emission control system is not operated as intended, the exhaust emissions may become worse.  
®
Information on AdBlue  
The AdBlue® consumption figures depend on the driving style, the operating temperature and the ambient  
temperature.  
You can check the remaining range and refill quantity on the instrument cluster display.  
Because AdBlue® freezes at temperatures below -11°C(+13°F), there may be limitations when filling at very low  
temperatures. While the vehicle is in motion, the system is heated to ensure effective emission control even at very  
low temperatures. During prolonged spells of cold weather with temperatures below -11°C (+13°F), and in extremely  
adverse conditions, it is possible that the AdBlue® cannot be defrosted and is not available for the emission control  
system.  
1. Stop the vehicle in a warm place.  
2. Wait until the AdBlue® becomes liquid again.  
3. If necessary, have refilling performed by a suitably qualified workshop.  
AdBlue® must be refilled independently of the service events. This may be necessary more frequently and between  
the service intervals.  
The AdBlue® tank must never run empty→  
.

Particulate filter  
Regeneration function  
During regeneration of the particulate filter, the accumulated soot inside the particulate filter is burnt to ash so that it  
does not become clogged. Regeneration takes place at periodic intervals at high temperatures. To achieve the high  
temperatures in the particulate filter, additional diesel is injected into the engine where it is burnt in the diesel  
oxidation catalytic converter to enable regeneration.  
Depending on the driver’s driving profile and the load placed on the engine, the amount of diesel fuel injected is  
continuously adjusted to maintain a high temperature in the particulate filter during regeneration. During post-  
injection of diesel fuel, small amounts of fuel may enter the oil circuit of the engine. During regular driving, this fuel  
evaporates again from the engine oil. If the engine oil temperatures are not high enough due to the driving profile or  
if a lot of short distances are driven, the fuel cannot evaporate from the engine oil and oil dilution can occur.  
An indicator light may light up in the instrument cluster display (→ Engine oil).  
Automatic regeneration  
The soot in the particulate filter is burnt off at high temperatures on a periodic basis.  
Volkswagen Commercial Vehicles recommends that you avoid making only short journeys to assist the regeneration  
of the particulate filter.  
The radiator fan may run on while the vehicle is moving or when the engine has been switched off.  
Regeneration is interrupted automatically when the vehicle is driven in the reserve range and the yellow indicator  
lamp lights up.  
NOTICE  
Aborted regeneration and the associated oil dilution may damage the engine.  
Do not switch off the engine unnecessarily while the indicator lamp is active.  
Avoid frequent short-distance driving and driving cycles at permanently low engine speeds or stationary  
operation.  
Noises, slight smells and increased engine speeds may occur during  
regeneration.
