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.
