Checking the AdBlue Tank Level of the Mercedes C-Class W205

Model: Mercedes Classe C W205 - Years 2014-2021
Part: AdBlue warning light

In this video, we can see how some latest generation diesel engines, like that of the Mercedes C-Class W205, are equipped with an emissions reduction system that uses AdBlue fluid: if the level of the tank containing this fluid is low, a control system prevents the car from starting. To check the level, from the driver's seat, turn on the instrumentation using the buttons on the right side of the steering wheel, select the Service menu on the central display, and in this screen choose AdBlue to view the tank content and the expected range before refueling.
