AdBlue is a special and innovative additive recently introduced in Diesel vehicles to significantly reduce pollution levels. After many miles driven, it can run out, and the warning light automatically appears on the dashboard display.

If you have encountered this issue, simply refill the AdBlue tank. But how do you do it? Let's find out. Before proceeding, do not forget to turn off the vehicle's engine.

Lift the hood and locate the AdBlue tank cap. It is very simple as it is indicated on the cap itself and is located next to the air conditioning recharge system. Unscrew the cap and, using a funnel, pour the new AdBlue until the tank is completely full.

At this point, screw the cap back on and lower the hood.
