Utility and action of the mass air flow meter of a Volkswagen Polo 8

.
So we start our article with the process and intent of your Volkswagen Polo 8 flowmeter.

The goal of the mass air flow sensor on Volkswagen Polo 8

The mass air flow sensor is a part that has been created 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 consequently important for the ECU to know the exact volume of air added into the engine to change the actions of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Volkswagen Polo 8, do not think twice to consult our article on this subject.

Mass air flow sensor operation on Volkswagen Polo 8

You should know that this process is quite simple to perform and you will not need advanced mechanical expertise to do it your self, a good way to avoid a trip to the workshop and a steep bill. See down below the different steps to stick to to perform this routine service act:

  • After having based the mass air flow sensor of your Volkswagen Polo 8 , you will have to dismantle it. To get this done, 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 taken apart, you will have the ability to continue to the step cleaning the mass air flow sensor of your Volkswagen Polo 8 . 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 disrupt the operation of the engine of your Volkswagen Polo 8. The goal of this cleaning will be to remove all its harmful particles to enable 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 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 careful, 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 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 Volkswagen Polo 8 , you should feel a noticeable difference in the behavior of your engine.
