Utility and action of the mass air flow meter of a Mercedes Classe Glc

.
So we begin our article with the process and intent of your Mercedes Classe Glc flowmeter.

The purpose of the mass air flow sensor on Mercedes Classe Glc

The mass air flow sensor is a component that has been developed quite recently and mainly equipped on diesel models. Indeed, with injection engines, the fuel and air intake has become very precise and it is therefore necessary for the ECU to know the exact volume of air loaded into the engine to adapt 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 Glc, do not think twice to seek advice from our article on this subject.

Mass air flow sensor operation on Mercedes Classe Glc

Now, we are going to have a look at how it functions, before trying to clean the mass air flow sensor of your Mercedes Classe Glc , you must already find out how it functions to do this routine service act correctly.

The mass air flow sensor is consequently mainly there to collect statistics on the air intake of your car. To achieve this, it must be installed just after the air intake of your Mercedes Classe Glc, i. e. just after the air filter. It is a pipe equipped with a sensor that will review the air in the intake and transfer the statistics to the ECU of your car.

Why clean the mass air flow sensor of a Mercedes Classe Glc?

The mass air flow sensor of your Mercedes Classe Glc can have complications and this is what we will try to see and understand what complications you might be facing!

Mass air flow sensor complications Mercedes Classe Glc

Here are the different complications that the air flow sensor of your Mercedes Classe Glc can bring about:

How do I clean the mass air flow sensor from a Mercedes Classe Glc?

After reviewing the operation and concerns that the flowmeter can bring about, we will look at how to solve these complications by describing to you how to clean the mass air flow sensor of your Mercedes Classe Glc . You should know that this operation is quite very easy to accomplish and you will not need advanced mechanical expertise to do it your self, a good technique to avoid a trip to the mechanic and a steep bill. Discover down below the different steps to follow to accomplish this routine service act:

  • After having located the mass air flow sensor of your Mercedes Classe Glc , you will have to dismantle it. To achieve this, act delicately, but you will just have to disassemble it on both sides of the air duct and detach the electrical plug on top of it.
  • Once disassembled, you will have the ability to proceed to the step cleaning the mass air flow sensor of your Mercedes Classe Glc . 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 correctly, it is in this sense that it will affect the operation of the engine unit of your Mercedes Classe Glc. The purpose of this cleaning will be to take out all its impure substances to allow it to work efficiently again.
  • Let soak the lower section 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 proceed to the very delicate cleaning of the flow meter filaments. You have to be very watchful, in any other case your mass air flow sensor will be permanently broken. With the help of a fine brush and solvent, delicately 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 Glc , you should feel a noticeable difference in the behavior of your engine unit.
