How do you reset the AdBlue warning light on the Peugeot 508?

Model: Peugeot 508 MK 2 - Years 2018-2026
Part: AdBlue warning light

To make the AdBlue warning light disappear from the instrument panel of the Peugeot 508, it will be necessary to top up the additional liquid inside the corresponding tank: to access the tank vent, you will need to open the rear hatch of the vehicle. By accessing the trunk compartment, it will be possible to lift the carpet at the base of the compartment and remove the spare wheel located underneath the carpet. In this way, it will be possible to locate a blue cap, which must be removed: the liquid can be inserted into the tank, thus making the warning light disappear.
