The AdBlue additive is used in modern diesel engines to reduce their exhaust emissions. The warning light, in addition to indicating that the reserve level has been reached and that a top-up is necessary, may also illuminate due to a temporary error and not turn off. In such a case, as shown in the video, you can intervene directly with a PC, but especially with the appropriate software, and reset it by connecting the latter to the car's ECU via a cable plugged into the USB port, following the various proposed steps to achieve the aforementioned reset.
