When the AdBlue warning light comes on in a Citroen C3 diesel vehicle, it means that it is necessary to top up the liquid inside the tank. The liquid tank is located next to the diesel tank, so to top up the liquid we need to open the fuel door and unscrew the blue cap. After removing the cap, pour the contents of the canister into the tank.

To reset the warning light, simply start the car engine and drive in a straight line for at least 20 minutes. If the warning light is not reset, it may be necessary to go to a mechanic for a check on the filling sensor.
