What does the AdBlue warning light indicate in the Audi A4 Avant and how can it be removed?

Model: Audi A4 B7 - Years 2004-2008
Part: AdBlue warning light

If the AdBlue light has come on in our Audi A4 Avant, it means that the pollution control fluid has reached a too low level and therefore needs to be topped up. To do this, we will need a 10-liter container that can be purchased at any car parts store. Once obtained, make sure the vehicle is turned off, then open the fuel door and unscrew the small blue cap on the right side. Then insert the tube from the container into the hole and pour in the necessary amount of fluid to reach the maximum level. To make the light disappear, we may need to drive a few kilometers.
