How to reset the Urea warning light on the Citroën C4 Picasso?

Model: Citroen C4 Picasso MK 2 - Years 2013-2022
Part: Warning light – error code

When the Urea warning light illuminates on the instrument cluster of the Citroën C4 Picasso, it means that the AdBlue additive liquid in the tank is nearly depleted and needs topping up. The cap for the additive tank is located in the boot: to access it, lift the carpet that serves as flooring and locate the cap at the bottom right of the spare wheel. Once the liquid has been poured in and the tank is completely full, the Urea warning light will turn off, and you can replace the carpet.
