How to Remove the AdBlue Warning Light in an Audi Q3?

Model: Audi Q3 8U - Years 2011-2018
Part: AdBlue warning light

If the AdBlue warning light has illuminated on the dashboard of your Audi Q3, it means that the emissions fluid has reached a too low level and needs to be refilled. To do this, you will need a 2.6-gallon jug of urea, which can be purchased at any auto parts store. Once you have it, turn off the engine and open the fuel door, then unscrew the small blue cap and insert the jug's nozzle into the opening. At this point, add the necessary amount of fluid to reach the maximum level, which will automatically turn off the warning light.
