More and more drivers are trying to maintain their cars on their own. This results in considerable savings because contemporary cars require more and more maintenance and are made up of more and more technical components that lead to new breakdowns or inconveniences. One of the problems that affects more and more Mercedes Cla owners is a clogged air flow meter, which will end in 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 Cla? . First, we will describe how your mass airflow sensor operates 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 Cla .
Utility and action of the mass air flow meter of a Mercedes Cla
.
So we start our content with the process and point of your Mercedes Cla flowmeter.
The intent of the mass air flow sensor on Mercedes Cla
The mass air flow sensor is a component that has been created actually quite lately and principally supplied on diesel models. In actual fact, 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 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 Cla, do not think twice to seek advice from our content on this subject.

- 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 cautious, 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 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.
