How to reset the AdBlue warning on the Nissan Qashqai

Model: Nissan Qashqai J12 - Years 2021-2026
Part: AdBlue warning light

Let's see how to reset the AdBlue warning on the Nissan Qashqai: in fact, after filling the tank, sometimes the system needs a procedure to recognize the new level and reset the alarm. After filling the tank (never up to the extreme limit) with high-quality AdBlue, close the cap, get in the car, turn on the ignition and wait for a minute, a minute and a half. Then turn off the car completely and wait another couple of minutes. Start the engine normally and drive for 5/15 minutes at a constant speed: this allows the ECU to record the new level and reset the alarm. Only if necessary, it may be necessary to disconnect the negative terminal of the battery for fifteen minutes, and then idle the engine for another 15 minutes. If the warning still does not disappear, it means there is a problem with the level sensor, or with the pump or injector.
