How to Refuel AdBlue in Citroen Models

Model: Citroen Citroen Various
Part: AdBlue warning light

If your new Citroen is equipped with a Diesel engine, it will certainly have a dedicated AdBlue tank, which is a special liquid that significantly reduces the pollution levels of this type of engine. After driving many miles, it is necessary to refill the tank to avoid running dry while driving and encountering problems. Here’s how to do it. First, completely turn off the car and park it safely. Then, go to the fuel filler flap, open it, and unscrew the blue cap. Pour the new AdBlue inside and, when finished, screw the cap back on. Close the flap, and you’re done.
