If the AdBlue alarm of your Peugeot 308 has been activated, it means that the fluid level is low or there is a problem with the system. Before resetting the alarm, it is necessary to check the AdBlue level and, if necessary, top it up. To do this, open the AdBlue tank cap, usually located near the fuel tank, and fill it with the specific fluid, being careful not to spill too much.

Once done, start the engine and drive for a while, as the alarm will automatically turn off after a couple of kilometers. If the alarm persists, there may be a fault in the AdBlue injection system and in this case it is advisable to contact a mechanic.
