Today, let's go over the instructions to reset the AdBlue warning light and restore the AdBlue fluid level on the Land Rover Discovery. First, get inside the vehicle and turn on the ignition; then check the amount of AdBlue that needs to be added, as shown in the video.

Once you add the new AdBlue fluid, the onboard computer will detect the new level, automatically resetting the AdBlue refill warning light. If it does not reset, you will need to use diagnostic software.
