More and more motorists are trying to take care of their vehicles by themselves. This outcomes in considerable savings because modern cars involve more and more maintenance and are done up of more and more technical parts that lead to new breakdowns or inconveniences. One of the problems that impacts more and more Mercedes Classe E owners is a clogged air flow meter, which will lead to a loss of power and black exhaust gases. Today we are going to check out how to clean the mass air flow sensor of your Mercedes Classe E? . First, we will describe how your mass airflow sensor works and its advantages, second, why it may be relevant to clean this sensor , and at last, how to clean the mass air flow sensor of a Mercedes Classe E .
Utility and action of the mass air flow meter of a Mercedes Classe E
.
So we begin our content page with the procedure and purpose of your Mercedes Classe E flowmeter.
The intent of the mass air flow sensor on Mercedes Classe E
The mass air flow sensor is a component that has been developed quite not too long ago and specifically outfitted on diesel models. In actual fact, with injection engines, the fuel and air intake has become very precise and it is therefore essential for the ECU to know the exact volume of air injected into the engine to modify the actions of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Mercedes Classe E, do not hesitate to consult our content page on this subject.
Mass air flow sensor operation on Mercedes Classe E

- Once disassembled, you will be able to move forward to the step cleaning the mass air flow sensor of your Mercedes Classe E . This sensor will, with time, get dirty and its two “filaments” that will give information to your computer on the quality and temperature of the air will no longer be able to collect data correctly, it is in this sense that it will disrupt the operation of the engine of your Mercedes Classe E. The intent of this cleaning will be to remove all its impure substances to enable it to work efficiently again.
- Let soak the lower part of your mass air flow sensor (not the plug part) in acetone or another solvent for a few minutes , which will remove most of the grime
- Now we’ll move on to the very delicate cleaning of the flow meter filaments. You have to be very watchful, otherwise your mass air flow sensor will be permanently broken. With the help of a fine brush and solvent, gently clean the two filaments of your mass air flow sensor . If you are too afraid of harming it, you can as well clean them with a brake fluid in the form of an aerosol by spraying the jet on these filaments.
.
Now you know how to clean the mass air flow sensor of your Mercedes Classe E , you should feel a noticeable difference in the behavior of your engine.
