If the AdBlue warning light is on in the instrument cluster of your Mercedes E-Class, it means you need to refill the emissions fluid as it has reached the minimum level. This is a very simple and quick operation; let's see how to proceed in this tutorial. First, purchase a 2.6-gallon jug of fluid at any auto parts store, then open the fuel door and unscrew the small blue cap on the left.
