Refill your AdBlue

What is AdBlue®?

AdBlue is a biologically degradable mixture that has been used by most automobile manufacturers since the introduction of the Euro 6 emission standard to reduce the noxious emissions from their diesel engines. In the meantime, AdBlue technology has become common in diesel vehicles.

Where is my AdBlue tank located?

You can look up in the user’s manual where the tank is located. In recent vehicles with AdBlue technology, this blue cap is right next to the fuel cap. In older models, the AdBlue tank is under the engine hood or in the trunk.

Does my vehicle use AdBlue?

  • AdBlue is used mainly in vehicles with Euro 6 diesel engines.
  • The most important vehicle brands that use AdBlue in certain models are Audi, BMW, Citroën, Ford, Infiniti, Jaguar, Land Rover, Mazda, Mercedes, Opel, Peugeot, Seat, Skoda, Toyota and Volkswagen.

When should I replenish the AdBlue tank?

As soon as the action radius falls under 2400 km, the on-board computer gives an automatic warning. When the AdBlue tank is completely empty, the vehicle cannot be started again, even after the tank has been filled. The tank must therefore be replenished as promptly as possible by the driver:

  • Either at the pump  

Various gas stations offer the possibility to fill up with AdBlue. You will find the AdBlue installation in the vicinity of the fuel installation for passenger vehicles. Attention: You must not fill up with AdBlue from the installation for trucks. They have a higher filling rate and that could damage the filling tank.

  • Or with an AdBlue bottle  

You can buy an AdBlue bottle in the shop of the gas station. This bottle has a handy screw cap that can be screwed on the filling opening of the vehicle. As soon as the tank is full, the screw cap stop filling automatically. We advise you to buy a bottle with a content that corresponds to the volume of your vehicles AdBlue tank.

The dealer no longer fills the AdBlue tank automatically when performing maintenance on the vehicle, because filling up with AdBlue is no longer part of standard maintenance.

How do I fill up my AdBlue tank?

You fill up with at least 4 litres when your AdBlue tank is empty. If the tank overflows, AdBlue can crystalize and clog the filler neck. So fill up the tank only when the indicator lamp warns you to fill up.

How can I pay for AdBlue?

  • The AdBlue refill can be paid for by using the Arval Fuel Card, directly at the pump or in the shop. Attention! There is no microchip in the Arval Fuel Card, unlike a normal bank card. You can only pay with the Arval Fuel Card if you swipe the card through the payment terminal. During the payment process you are also requested to enter the correct mileage of your vehicle.
  • You can also pay with most other fuel cards. If you do not have a fuel card, you use our digital declaration form, whereby you upload your receipts through our website.

Are precautionary measures needed when it is very cold?

AdBlue crystalizes at -11C° but extra precautionary measures at such a temperature are not needed. Each vehicle has an automatic heating system that makes AdBlue liquid again.

What happens if my vehicle is stationary for several months?

AdBlue remains effective for more than a year. However we advise you to empty the tank and to renew the AdBlue fluid, if the vehicle was not sufficiently driven or was left stationary.
