How to Remove the AdBlue Warning Light in the Audi A6?

Model: Audi A6 C7, MK 4 - Years 2011-2018
Part: AdBlue warning light

If the AdBlue warning light has turned on in your Audi A6, it means that the emissions fluid has reached a too low level and needs to be topped off. This is a fairly simple operation; let's see how to proceed in this short tutorial. First, obtain a 2.6-gallon container of fluid, available at any auto parts store. Then, open the fuel door and, using a 17mm socket wrench, unscrew the small black cap located on the right. Finally, insert the container's nozzle into the opening, add the necessary amount of fluid, and tighten the cap.
