How to reset the AdBlue warning light on a Peugeot 308

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

First of all, let's see a normal reset after filling the tank of the Peugeot 308: turn on the instrument panel; the system automatically detects that the tank has been filled, and resets the system after a few minutes (which can take up to 20/30). If we have a problem with the system, we can instead intervene as shown in the video, which demonstrates an advanced technical intervention; perhaps following a defective pump, or a sensor or injector, which have prevented the car from starting. Through a professional diagnostic tool, the AdBlue system of the ECU is temporarily disabled, allowing the vehicle to restart. It is a solution that does not fix the fault and can cause damage to the particulate filter, and can only be used in case of emergency for a quick restart.
