One of the complications that affects more and more Mercedes Classe E 4 owners is a clogged air flow meter, which will lead to a loss of power and black exhaust fumes. Today we are going to look at how to clean the mass air flow sensor of your Mercedes Classe E 4? . First, we will explain how your mass airflow sensor functions and its value, 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 4 .
Utility and action of the mass air flow meter of a Mercedes Classe E 4
.
So we start our content with the process and point of your Mercedes Classe E 4 flowmeter.
The aim of the mass air flow sensor on Mercedes Classe E 4
The mass air flow sensor is a part that has been created quite lately and mainly equipped on diesel models. Obviously, with injection engines, the fuel and air intake has become very precise and it is so essential for the ECU to know the exact volume of air injected into the engine to change the behaviour 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 4, do not hesitate to consult our content on this subject.

- Once disassembled, you will have the ability to continue to the step cleaning the mass air flow sensor of your Mercedes Classe E 4 . This sensor will, as time passes, get dirty and its two “filaments” that will give information to your computer on the quality and temperature of the air will no longer have the ability to collect data properly, it is in this sense that it will affect the operation of the engine unit of your Mercedes Classe E 4. The aim of this cleaning will be to take out all its harmful particles to allow 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 take out most of the grime
- Now we’ll move on to the very gentle cleaning of the flow meter filaments. You have to be very careful, otherwise your mass air flow sensor will be permanently damaged. 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 damaging it, you can as well clean them with a brake fluid in the form of an aerosol by spraying the jet on these filaments.
