AdBlue level low

The indicator lamp lights up yellow.

The instrument cluster display shows a text message Refill AdBlue! No engine start in XXX km (XXX miles).

The remaining range is approximately 1,000 km (600 miles).

1. Refill AdBlue within the specified distance (→ AdBlue).

AdBlue level too low

The warning lamp lights up red.

The instrument cluster display shows a text message Refill AdBlue! Engine start disabled.

The AdBlue level is too low.

The yellow indicator lamp and the message in the instrument cluster were ignored. It is no longer possible to restart the engine.

1. Park the vehicle.

2. Refill the minimum quantity of AdBlue (→ AdBlue).

Observe the following information to help ensure the long-term functionality of the exhaust system and the catalytic converter in the

petrol engine:

—Only use fuel that has been approved for the vehicle.

—Do not run the fuel tank empty (→ Fuel types and refuelling).

—Do not overfill 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 . Volkswagen recommends using an authorised Volkswagen repairer. Otherwise unburned fuel can enter

the exhaust system and escape into the environment. The catalytic converter can also be damaged by overheating.

The emissions may have a sulphur-like smell even if the emission purification system is working properly.

Function

The particulate filter is dependent on the vehicle equipment and filters out soot particles in the exhaust gas.

Regeneration

In normal vehicle operation, the filter cleans itself. If it is not possible for the filter to clean itself, for example, if the vehicle is only ever

used for short trips, the filter will become saturated with soot. The diesel particulate filter requires cleaning (regeneration).

Noises, slight smells and increased engine speeds may occur during regeneration. The radiator fan may run on while the vehicle is

moving or when the engine has been switched off.

To assist the regeneration of the particulate filter, Volkswagen recommends that you avoid making frequent short journeys.

The soot in the particulate filter is burnt off at high temperatures on a periodic basis. During the periodic regeneration process,

the yellow indicator lamp

does not light up.

Irregular engine running and faults

Irregular engine running or faults when driving may be a sign of poor fuel quality.

1. Reduce speed immediately.

2. Drive to the nearest suitably qualified workshop at medium engine speeds and low loads on the engine. Volkswagen

recommends using an authorised Volkswagen repairer.

3. If these symptoms occur immediately after refuelling, switch off the engine immediately to avoid any subsequent damage.

Seek expert assistance.

Particulate filter clogged with soot

The indicator lamp lights up yellow.

The particulate filter is saturated with soot and requires regeneration.

Prerequisite for regeneration trip: the engine is at operating temperature.

For petrol engines

1.0 l to 1.8 l

1. Drive at a speed between around 50 km/h and 120 km/h (around 30 mph and 75 mph).

The achieved temperature increase can burn the soot off the filter.

2. End the regeneration drive only when the indicator lamp goes out.

3. Go to a suitably qualified workshop without delay if the indicator lamp continues to light up after driving for approximately

40 minutes. Volkswagen recommends using an authorised Volkswagen repairer.

2.0 l and 3.0 l

1. Drive at a speed of at least 80 km/h (around 50 mph).

2. To allow the vehicle to coast while a gear is engaged, take your foot off the accelerator completely for a few seconds.

3. Repeat this procedure (accelerate and coast) until the indicator lamp goes out.

4. If the indicator lamp does not go out after some time, go immediately to a suitably qualified workshop. Volkswagen recommends

using an authorised Volkswagen repairer.

For diesel engines

1. Drive at a speed between around 50 km/h and 120 km/h (around 30 mph and 75 mph).

The achieved temperature increase can burn the soot off the filter.

2. End the regeneration drive only when the indicator lamp goes out.

3. Go to a suitably qualified workshop without delay if the indicator lamp continues to light up after driving for approximately

40 minutes. Volkswagen recommends using an authorised Volkswagen repairer.

If a message requesting you to refuel appears additionally on the instrument cluster display during the regeneration drive, the

regeneration process of the particulate filter could be interrupted.

1. Refuel if necessary and then continue the regeneration drive.

Emissions-relevant fault

The indicator lamp lights up yellow.

Fault in an emissions-relevant component that can damage the vehicle.

1. Go to a suitably qualified workshop and have the engine and exhaust system checked. Volkswagen recommends using an

authorised Volkswagen repairer.

Misfiring

The indicator lamp flashes yellow.

Misfiring is occurring that can damage the vehicle.

1. Go to a suitably qualified workshop and have the engine and exhaust system checked. Volkswagen recommends using an

authorised Volkswagen repairer.

WARNING

Sudden braking or driving manoeuvres, for example when an indicator lamp lights up or due to irregular engine running, can lead to

accidents. This can cause severe or fatal injuries.

● Ensure that your speed and driving style are always appropriate for the current visibility, weather and road/traffic conditions.

● Always observe the applicable country-specific traffic regulations.

There may be engine faults and fuel consumption may be higher if the indicator lamps are lit up or flashing.

Observe any country-specific legislation when securing your vehicle in the event of a breakdown.

WARNING

In the event of a sudden driving or braking manoeuvre or accident, a loose breakdown set, spare wheel, temporary spare wheel or

loose vehicle toolkit could be flung though the vehicle interior. This can result in serious or fatal injuries.

● Always ensure that the vehicle toolkit, breakdown set and spare wheel or temporary spare wheel are always properly secured in

the luggage compartment.

WARNING

Working with unsuitable tools or damaged tools from the vehicle toolkit can lead to accidents. This can result in serious or fatal

injuries.

● Never work with unsuitable or damaged tools from the vehicle toolkit.

● Seek expert assistance if no suitable vehicle tools are available.
