Peugeot 2008: Practical information / AdBlue® (BlueHDi)

Peugeot 2008. AdBlue® (BlueHDi)

To respect the environment and ensure compliance with the Euro 6 standard, without adversely affecting the performance or fuel consumption of its Diesel engines, PEUGEOT has taken the decision to equip its vehicles with a system that associates SCR (Selective Catalytic Reduction) with a Diesel Particle Filter (DPF) for the treatment of exhaust gases.

SCR system

Using a liquid called AdBlue® that contains urea, a catalytic converter turns up to 85% of the nitrogen oxides (NOx) into nitrogen and water, which are harmless to health and the environment.

Peugeot 2008. AdBlue® (BlueHDi) The AdBlue® is contained in a special tank holding about 15 litres.

Its capacity allows a driving range of approximately 5,600  miles (9,000  km), which may vary considerably depending on your driving style.

An alert system is triggered once the reserve level is reached: it is then possible to drive for a further 1,500 miles (2,400  km) before the tank is empty and the vehicle blocked.

Peugeot 2008. AdBlue® (BlueHDi) For more information on the Warning and indicator lamps and the associated alerts, or the Indicators, please refer to the corresponding sections.

Peugeot 2008. AdBlue® (BlueHDi) Once the AdBlue® tank is empty, a system required by legislation prevents starting of the engine.

If the SCR system is faulty, the level of emissions from the vehicle will no longer meet the Euro 6 standard: the vehicle becomes polluting.

In the event of a confirmed SCR system malfunction, it is essential to visit a PEUGEOT dealer or a qualified workshop. After 685 miles (1,100 km), a device is automatically activated to prevent the engine from starting.

In both cases, a range indicator indicates the distance that can be travelled before the vehicle is stopped.

Peugeot 2008. AdBlue® (BlueHDi) Freezing of the AdBlue®

AdBlue® freezes at temperatures below around -11°C.

The SCR system includes a heater for the AdBlue® tank, allowing you to continue driving in very cold conditions.

Supply of AdBlue®

It is recommended that the AdBlue® be topped up as soon as the first alert is issued indicating that the reserve level has been reached.

Peugeot 2008. AdBlue® (BlueHDi) In order to ensure that the SCR system operates correctly:

  • Use only AdBlue® fluid that meets the ISO 22241 standard.
  • Never transfer AdBlue® to another container: it would lose its purity.
  • Never dilute AdBlue® with water.

AdBlue® can be obtained from a PEUGEOT dealer or a qualified workshop.

Storage recommendations

AdBlue® freezes at about -11°C and deteriorates above +25°C. Containers should be stored in a cool area and protected from direct sunlight.

Under these conditions, the fluid can be kept for at least a year.

If the fluid has frozen, it can be used once it has completely thawed out in the ambient air.

Peugeot 2008. AdBlue® (BlueHDi) Never store AdBlue® containers in your vehicle.

Precautions for use

AdBlue® is a urea-based solution. This fluid is non-flammable, colourless and odourless (when kept in a cool place).

In the event of contact with the skin, wash the affected area with soap and running water. In the event of contact with the eyes, immediately rinse the eyes with large amounts of water or with an eye wash solution for at least 15 minutes. Seek medical attention if you feel a persistent burning sensation or irritation.

If swallowed, immediately wash out the mouth with clean water and then drink plenty of water.

In certain conditions (high temperature, for example), the risk of release of ammonia cannot be excluded: do not inhale the fluid. Ammonia vapours have an irritant effect on mucous membranes (eyes, nose and throat).

Peugeot 2008. AdBlue® (BlueHDi) Store AdBlue® out of the reach of children, in its original container.


Before starting the top-up procedure, ensure that the vehicle is parked on a flat and level surface.

In wintry conditions, ensure that the temperature of the vehicle is above -11  °C.

Otherwise the AdBlue® may be frozen and so cannot be poured into its tank. Park the vehicle in a warmer area for a few hours to allow the top-up to be carried out.

Peugeot 2008. AdBlue® (BlueHDi) Never put the AdBlue® into the Diesel fuel tank.

Peugeot 2008. AdBlue® (BlueHDi) If any AdBlue® is splashed, or if there are any spillages on the bodywork, rinse immediately with cold water or wipe with a damp cloth.

If the fluid has crystallised, clean it off using a sponge and hot water.

Peugeot 2008. AdBlue® (BlueHDi) Important: in the event of a top-up after a breakdown because of a lack of AdBlue, it is essential to wait around 5 minutes before switching on the ignition, without opening the driver’s door, unlocking the vehicle, introducing the key into the ignition switch, or introducing the key of the “Keyless Entry and Starting ” system into the passenger compartment.

Switch on the ignition, then wait for 10 seconds before starting the engine.

  • Switch off the ignition and remove the key from the switch to switch off the engine.


  • With Keyless Entry and Starting, press the "START/STOP" button to switch off the engine.

Peugeot 2008. AdBlue® (BlueHDi)

  • Turn the blue cap of the AdBlue®   tank a 6th of a turn anti-clockwise and remove it.
  • With a container of AdBlue®: after checking the expiry date, read the instructions on the label carefully before pouring the contents of the container  into the vehicle's AdBlue tank.
  • With an  AdBlue® pump: introduce the nozzle and fill the tank until the nozzle automatically cuts out.

Peugeot 2008. AdBlue® (BlueHDi) In order not to overfill the AdBlue® tank:

  • Add between 10 and 13 litres using AdBlue® containers.
  • Stop after the nozzle’s first automatic cut-out, if you are refilling at a service station.

    The system only registers AdBlue® top-ups of 5  litres or more.

Peugeot 2008. AdBlue® (BlueHDi) If the AdBlue® tank is completely empty

  • which is confirmed by the message "Top up  AdBlue: Starting impossible"
  • it is essential to add at least 5 litres.


    Unless otherwise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine. Otherwise, have them checked by a PEUGEOT dealer or a qualified workshop...


    In certain situations, you must allow the vehicle to free-wheel (while being towed, on a rolling road, in an automatic car wash, or being transported by rail or sea freight, etc...
