How to reset the AdBlue warning light on the Peugeot 308?

Model: Peugeot 308 T9, MK 2 - Years 2013-2021
Part: AdBlue warning light

When the AdBlue warning light illuminates on the Peugeot 308 dashboard, it means the additional fluid in the designated tank is nearly depleted. To turn off the light, you need to top up the fluid by pouring it into the appropriate tank. To do this, open the boot and lift the carpet that serves as flooring, unscrewing the cap next to the spare wheel. From here, you can pour the additional fluid until the tank is completely full. This will cause the warning light to disappear from the dashboard.
