If the AdBlue warning light has come on in your car, it means that the anti-pollution fluid has reached the minimum level and therefore needs to be topped up. This is an extremely simple and quick operation; let’s see how to proceed in this tutorial.

First, purchase a 10-litre canister of urea from a car parts store, then turn off the engine, open the boot lid, and lift the floor panel.

Next, unscrew the indicated blue cap, insert the supplied tube from the canister into the hole, and add the necessary amount of fluid to reach the maximum level.
