AdBlue is the additive used to reduce nitrogen oxide emissions in diesel engines. Modern vehicles have an additional tank for this additive.

The filler cap is located next to the diesel fuel cap and is usually blue. When the additive level drops below a predetermined value, a warning appears on the dashboard indicating that AdBlue needs to be topped up; otherwise, the engine will not start after a certain number of miles.

Once you have topped up the additive, the warning on the instrument panel will disappear.
