How to Top Up AdBlue in the Citroen C4 Picasso

Model: Citroen C4 Picasso MK 2 - Years 2013-2022
Part: AdBlue warning light

In this video, you will see how to top up AdBlue in the Citroen C4 Picasso after the warning light on the dashboard comes on. The AdBlue tank is located in the boot, specifically under the boot floor. Unscrew the cap and insert a funnel to assist with the top-up. Once finished, close the tank and reposition everything as it was originally. To reset the dashboard, use a suitable tester connected to the car's OBD port, as it cannot be done directly from the multimedia display. Once done, the car will be able to run normally again.
