If the AdBlue warning light is on in the instrument cluster of your Mercedes E-Class, it means that the fluid in the emissions system has reached the minimum level and needs to be topped off. This is a very simple and quick operation; let's see how to proceed in this tutorial.

First, purchase a jug of urea at an auto parts store.

Then, ensure the engine is off and open the fuel door. Next, unscrew the blue cap, insert the jug's nozzle into the opening, and add the necessary amount of fluid to reach the maximum level.
