Get Fuel and exhaust purification -> AdBlue Guide for Volkswagen California Van Third Generation (2015-2024)

AdBlue®

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 Volkswagen 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.

The expected AdBlue^®consumption is 0.5 – 2.0 l/1,000 km and can vary and deviate depending on the driving style,

the operating and ambient temperature.

With some equipment levels, the remaining range and refill quantity can be checked 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→

.

Warning and prompting system with low fill level

Always add AdBlue^®when a prompt to add it appears in the instrument cluster display.

AdBlue^®in normal operating range. Remaining range of 2000 km or 2400 km(depending on equipment).

AdBlue^®can be added, but it is not necessary.

As of a remaining range of 2,000 or 2,400 km(depending on equipment), the instrument cluster display will indicate

that AdBlue^®must be refilled. The respective remaining range at that time is indicated in this prompt.

If this prompt is ignored, the yellow indicator lamp lights up from aremaining range of 1000 km. A message

informing you that it will no longer be possible to restart the engine in XXX km appears in the instrument cluster

display.

It will no longer be possible to restart the engine if the yellow indicator lamp is still ignored and the displayed

remaining range is 0 km. The red warning lamp lights up.

Warning and prompting system in the event of faults

482

If there is a fault in the exhaust gas purification system or if the tank has not been filled with standard-compliant

AdBlue^®in accordance with ISO-22241-1, the white or yellow indicator lamps light up . Theremaining range is

1,000 km when the white or yellow indicator lamps light up (→ Emission-relevant components).

If the yellow indicator lamps are ignored, the red warning lamps light up

. There is aremaining range of 0 km and

it is no longer possible to restart the engine (→ Emission-relevant components).

CAUTION

AdBlue^®is an irritant and corrosive fluid that can damage the skin, eyes and breathing passages upon contact.

®

● Always observe the instructions for use when using AdBlue. Compliance with the instructions usually prevents

users from coming into contact with AdBlue^®.

● AdBlue^®must be kept only in the closed original container. Never use empty food tins, bottles or other

containers.

● Always store AdBlue^®in a safe place out of reach of children.

● If AdBlue^®gets into the eyes, immediately rinse your eyes with plenty of water for at least 15 minutes and consult

a doctor.

● If AdBlue^®comes into contact with the skin, immediately rinse your skin with plenty of water for at least

15 minutes and consult a doctor in the case of skin irritations.

● If AdBlue^®is swallowed, immediately rinse the mouth out with plenty of water for at least 15 minutes. Do not

induce vomiting unless instructed to do so by a doctor. Seek medical assistance immediately.

NOTICE

If the AdBlue^®level is too low, the vehicle cannot be restarted after the ignition has been switched off. Starting with

jump leads is also not possible.

● Refill a sufficient quantity of AdBlue^®at the latest when the remaining distance reaches approximately 1,000 km.

®

● Never allow the AdBlue tank to run empty.

● Observe the remaining range displayed in the instrument cluster display.

NOTICE

Improper use of AdBlue^®may cause damage to the vehicle that is not covered by the warranty.

®

● Only use and add AdBlue that complies with the standard ISO-22241-1.

®

● Never add water, fuel or additives to the AdBlue .

®

● Never fill AdBlue into the diesel fuel tank.

● Do not permanently carry the refill bottle in the vehicle. The bottle may develop a leak following changes in

temperature and damage and the AdBlue^®may damage the vehicle interior.

.

1. Park the vehicle on a level surface and switch off the ignition.

2. Open left-hand front door.

3. Open the tank flap.

®

4. Remove the cap from the AdBlue filler neck.

5. Insert the cap into the opening provided above the fuel tank filler neck.

If a message about the AdBlue^®level appears on the instrument cluster display, add at least the minimum refill

quantity. A smaller refill amount is insufficient.

Use only AdBlue^®that complies with the standardISO-22241-1.

Filling with the refill bottle

Observe the manufacturer’s use-by specifications, instructions and information on the refill bottle.

1. Remove the screw top of the refill bottle.

Preparing to continue the journey

®

1. Screw in the cap on the AdBlue filler neck until it engages.

2. Close the tank flap.

3. Close the left-hand front door.

4. Switch on the ignitiononly for at least 30 seconds so that refilling can be detected by the system.

5. Then start the engine afterwards.

NOTICE

Overfilling AdBlue^®may damage the tank system and the vehicle.

● Do not fill with more than the maximum refill quantity indicated on the instrument cluster display.

● Remove any spilled AdBlue^®as quickly as possible with a damp cloth and plenty of water.

®

● Remove any crystallised AdBlue with water and a sponge.

When filling with an AdBlue^®filler nozzle, you may notice an

odour.

Suitable AdBlue^®refill bottles are available from a correspondingly qualified

workshop.

Particulate filter

Fig. 1 Upper section of the centre console: buttons for

particulate filter regeneration (illustration).

Regeneration function

During regeneration of the particulate filter, the accumulated soot inside the filter is burnt to ash so that the filter

does not become clogged. Regeneration takes place at periodic intervals at high temperatures. In order to achieve

the high temperatures in the particulate filter, additional diesel is injected into the engine which is burnt in the diesel

oxidation catalytic converter, thus allowing the 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 the post-

injection of diesel, small amounts of fuel may enter the oil circuit in the engine. This fuel will evaporate from the

engine oil again during regular driving. If the engine oil temperatures are not high enough due to the driving profile,

or if you drive a lot of short distances, the fuel cannot evaporate from the engine oil and this can cause oil thinning.

An indicator lamp may light up on the instrument cluster display (→ Engine oil).

Automatic regeneration

Automatic regeneration occurs at regular intervals during everyday driving and is not shown on the display.

To assist the regeneration of the particulate filter, avoid making only short journeys.

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.

Manual regeneration (stationary regeneration)

2

The automatic regeneration of the particulate filter can be delayed via the→ Fig. 1

button, e.g. for driving into

closed halls. You can only postpone regeneration if the indicator lamp in the button lights up. Regeneration is

about to start when the indicator lamp in the button lights up. You can no longer postpone regeneration once it
