How to Reset the AdBlue Warning Light on a Peugeot 308

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

To reset the AdBlue warning light on a Peugeot 308, top up the fluid through the designated filler located inside the boot. To access it, open the rear hatch so you can lift the carpet that acts as flooring. At the bottom right, next to the spare wheel, you will find the filler where you can pour in the liquid. Once the top-up is complete, connect the diagnostic tool to the OBD port located in front of the gear lever to permanently reset the AdBlue warning light.

How to Reset the Tyre Pressure Light on the Opel Grandland X

While driving, if you notice the tyre pressure warning light coming on, first check the actual inflation pressure of the tyres and, if necessary, restore the pressures recommended by the manufacturer. After restoring the correct pressures, you need to reset the warning light that has illuminated on the instrument cluster. To do this, locate the reset button on the lower central console. Press this button and hold it down for at least 3 seconds, after which the low pressure indication will turn off.
