In the Mercedes GLC, how do you reset the adblue warning light?

Model: Mercedes Glc C254, X254, MK 2 - Years 2022-2026
Part: Checks and maintenance

The adblue additive is used in newly built diesel engines to reduce emissions, as recently established. It is contained in a specific tank and when the quantity reaches reserve, the warning light on the dashboard lights up, so it is necessary to top up. If the warning light remains on even after topping up, it is necessary to go to the workshop and reset the alarm with an electronic device like the one explained in the video. In practice, this device connects to the car's OBD socket and after the appropriate configurations, access to diagnostics and finally to the anomaly to be deleted is obtained.
