More and more motorists are trying to maintain their vehicles by themselves. This results in significant cost savings because contemporary cars involve more and more routine service and are done up of more and more technical components that lead to new breakdowns or inconveniences. One of the problems that affects more and more Mercedes Classe A owners is a clogged air flow meter, which will end in a loss of power and black exhaust fumes. In this article we are going to take a look at how to clean the mass air flow sensor of your Mercedes Classe A? . First, we will teach you how your mass airflow sensor operates and its usefulness, second, why it might be important to clean this sensor , and at last, how to clean the mass air flow sensor of a Mercedes Classe A .
Utility and operation of the mass air flow meter of a Mercedes Classe A
.
So we begin our content with the procedure and goal of your Mercedes Classe A flowmeter.
The purpose of the mass air flow sensor on Mercedes Classe A
The mass air flow sensor is a component that has been developed quite recently and specifically supplied on diesel models. In actual fact, with injection engines, the fuel and air intake has become very precise and it is so important for the ECU to know the exact volume of air loaded 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 A, do not think twice to seek advice from our content on this subject.
Mass air flow sensor operation on Mercedes Classe A
Now, we are going to have a look at how it operates, before trying to clean the mass air flow sensor of your Mercedes Classe A , you must already find out how it functions to do this routine service work accurately.
The mass air flow sensor is therefore specifically there to collect statistics on the air intake of your motor vehicle. To achieve this, it must be installed just after the air intake of your Mercedes Classe A, i. e. just after the air filter. It is a pipe supplied 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 A?
The mass air flow sensor of your Mercedes Classe A can have problems and this is what we will try to discover and figure out what problems you might be facing!
Mass air flow sensor problems Mercedes Classe A
Here are the different problems that the air flow sensor of your Mercedes Classe A can generate:
- higher fuel consumption: Because a dirty flow meter will necessarily end in excessive fuel consumption because of poor air flow…
- Power loss: Related to the same issue, this lack of air can generate a loss of power to your engine.
- Difficulties starting the automobile: Finally, one of the last traditional problems linked to a dirty flowmeter will be that your Mercedes Classe A will have more troubles to begin the car.
How do I clean the mass air flow sensor from a Mercedes Classe A?
After looking at the operation and problems that the flowmeter can generate, we will look at how to resolve these problems by explaining to you how to clean the mass air flow sensor of your Mercedes Classe A . You should know that this process is quite simple to conduct and you will not need advanced mechanical skills to do it your self, a good technique to avoid a trip to the garage and a steep bill. Discover below the different steps to stick to to conduct this routine service act:
- After having found the mass air flow sensor of your Mercedes Classe A , you will have to dismantle it. To achieve this, work delicately, 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 continue to the step cleaning the mass air flow sensor of your Mercedes Classe A . This sensor will, over 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 affect the operation of the engine unit of your Mercedes Classe A. The purpose of this cleaning will be to remove all its impurities 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 proceed 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 damaged. 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 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 A , you should feel a noticeable difference in the behavior of your engine unit.
