How to Remove the AdBlue Warning Light on the Citroen C4 Cactus?

Model: Citroen Cactus MK 1 - Years 2014-2020
Part: AdBlue warning light

If the AdBlue warning light has illuminated on the dashboard of your Citroen C4 Cactus, it means that the fluid level in the emissions system has reached the minimum and needs to be topped up. This is a very simple and quick operation; follow these steps. First, purchase a canister of urea from your trusted car parts store. Ensure the engine is off, open the boot, and remove both the floor panel and the tool basket. Next, unscrew the indicated cap, pour the required amount of fluid into the hole, and drive a few miles.
