In this video tutorial, you can see how to reset the AdBlue warning light on the Citroen C4 Picasso. First, refer to the information in the vehicle's user and maintenance manual.

Once you have read all the information in the manual, purchase a container of at least 10 litres of quality Urea (AdBlue) to avoid damaging the system; it must be certified. The urea tank is 17 litres and is located at the back of your car's boot under the mat; lift the mat, unscrew the blue cap counter-clockwise, and insert the funnel tube; refill with urea and then replace the cap. Now, if you start the vehicle, you will see that the AdBlue warning light has been reset.
