If the AdBlue warning light has come on in the instrument cluster of your Peugeot 308, it means that the anti-pollution fluid has reached the minimum level and, consequently, 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 your trusted auto parts store, then turn off the engine and open the rear hatch.

Next, lift the floor panel, unscrew the indicated cap, and pour the required amount of fluid into the hole.
