How to Reset the AdBlue Warning Light and Replace AdBlue in the Peugeot 308

Model: Peugeot 308 T9, MK 2 - Years 2013-2021
Part: AdBlue warning light

AdBlue is a special additive used in Diesel engines to reduce the amount of pollutants released into the air. After driving a considerable distance, it is necessary to refill the dedicated tank. Whenever the level is too low, a warning light appears on the dashboard. Here’s how to do it. First, ensure the car is off and obtain a new container of AdBlue. Next, go to the rear of the car and open the fuel flap. Unscrew the blue cap. Using a funnel or a rubber hose, pour the new AdBlue into the dedicated tank. Refit the cap and close the flap. At this point, the warning light should also have disappeared.
