How to maintain our Fiat Ducato with AdBlue properly

Model: Fiat Ducato X290 - Years 2014-2026
Part: AdBlue warning light

In this video we see that on the display of this Fiat Ducato the message "restart impossible between 527 km" has appeared, indicating a blockage due to the next AdBlue depletion. The YouTuber advises not to completely fill the tank in order to avoid overloading (in fact, the ultrasonic sensor needs an air bubble to measure correctly). Before refueling, remove any dried AdBlue crystals from the tank opening. After refilling, close the cap and wait for at least a minute with the key in the "ignition" position but without starting the engine. In vehicles with Keyless entry, briefly press the start button without pressing the brake to activate the instrument panel. Allow the display time to update the AdBlue range and make the warning light disappear. There are errors to avoid, such as overfilling the tank, which makes measurement impossible. Check the bottling date of the AdBlue, which has a one-year expiration date. Discard it if it has been bottled for longer. Remember that driving with too low AdBlue levels can lead to engine blocks; it is better to top up with a few liters more frequently, and regularly clean the nozzle and sensor from crystallized deposits.
