To reset the AdBlue warning light on the Peugeot Expert, top up the tank with the necessary amount of additive fluid: locate the blue cap that seals it. This cap is next to the fuel filler cap and can be accessed by opening the flap: once removed, you can add the required amount of fluid into the tank.

At this point, close the cap and check that the warning light has completely disappeared from the dashboard.
