More and more car owners are trying to take care of their vehicles by themselves. This results in substantial cost savings because modern cars involve more and more maintenance and are made up of more and more technical components that result in new breakdowns or inconveniences. One of the complications that disturbs more and more Mercedes Classe Cls owners is a clogged air flow meter, which will bring about a loss of power and black exhaust gases. In this article we are going to examine how to clean the mass air flow sensor of your Mercedes Classe Cls? . First, we will explain 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 Cls .
Utility and operation of the mass air flow meter of a Mercedes Classe Cls
.
So we begin our article with the operation and goal of your Mercedes Classe Cls flowmeter.
The goal of the mass air flow sensor on Mercedes Classe Cls
The mass air flow sensor is a component that has been created actually quite recently and principally outfitted on diesel models. In truth, 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 injected into the engine to adapt 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 Cls, do not hesitate to consult our article on this subject.
Mass air flow sensor operation on Mercedes Classe Cls
Now, we are going to check out how it works, before trying to clean the mass air flow sensor of your Mercedes Classe Cls , you must already figure out how it works to do this maintenance action accurately.
The mass air flow sensor is consequently principally there to get statistics on the air intake of your motor vehicle. To do this, it must be installed just after the air intake of your Mercedes Classe Cls, i. e. just after the air filter. It is a pipe outfitted with a sensor that will review the air in the intake and transmit the statistics to the ECU of your car.
Why clean the mass air flow sensor of a Mercedes Classe Cls?
The mass air flow sensor of your Mercedes Classe Cls can have complications and this is what we will try to see and figure out what complications you may be struggling with!
Mass air flow sensor complications Mercedes Classe Cls
Here are the different complications that the air flow sensor of your Mercedes Classe Cls can trigger:
- higher fuel consumption: Because a dirty flow meter will actually result in more significant fuel consumption because of poor air flow…
- Power loss: Linked to the same problem, this lack of air can trigger a loss of power to your engine.
- Difficulties starting the car: Finally, one of the last traditional complications linked to a dirty flowmeter will be that your Mercedes Classe Cls will have more issues to begin the car.
How do I clean the mass air flow sensor from a Mercedes Classe Cls?
After reviewing the operation and complications that the flowmeter can trigger, we will look at how to fix these complications by showing to you how to clean the mass air flow sensor of your Mercedes Classe Cls . You should know that this operation is actually quite simple to conduct and you will not need advanced mechanical skills to do it yourself, a good method to avoid a trip to the mechanic and a steep bill. Discover below the different steps to follow to conduct this maintenance act:
- After having found the mass air flow sensor of your Mercedes Classe Cls , you will have to dismantle it. To do this, action gently, but you will just have to disassemble it on both sides of the air duct and disconnect 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 Cls . 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 have the ability to collect data accurately, it is in this sense that it will disturb the operation of the engine of your Mercedes Classe Cls. The goal of this cleaning will be to take out all its harmful particles 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 move on to the very gentle cleaning of the flow meter filaments. You have to be very watchful, 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.
.
Now you know how to clean the mass air flow sensor of your Mercedes Classe Cls , you should feel a noticeable difference in the behavior of your engine.
