How to Reset the AdBlue Warning Light on a Renault Master

Model: Renault Master MK 3 - Years 2010-2023
Part: AdBlue warning light

If you notice that the AdBlue warning light is illuminated on your vehicle's instrument panel and simultaneously a certain number of miles appears on the onboard computer display indicating that the engine will no longer start, follow the simple steps outlined here to reset the light. When this orange light comes on, do not worry, as the onboard computer is indicating the need to top up the additive at least above the minimum level. To do this, open the fuel flap located on the right side of the vehicle and locate the blue cap next to the fuel cap. Unscrew the cap and proceed to fill the tank with the additive. This way, when you turn the ignition back on, the light will be off.
