How to Top Up AdBlue in a Peugeot Expert

Model: Peugeot Expert Mark2, MK 2 - Years 2008-2016
Part: AdBlue warning light

AdBlue is a special additive introduced in recent years in Diesel vehicles. Its purpose is to reduce environmental impact simply and effectively. After driving several miles, the amount of liquid in the respective tank may decrease until it runs out, making it necessary to top it up. But how do you do it? First, ensure that the engine is off, then open the front door (driver's side) and locate the small blue cap in the lower area. Unscrew it and, using a funnel or a rubber hose, pour the new AdBlue into the tank. Finally, screw the cap back on.
