More and more motorists are trying to take care of their cars on their own. This outcomes in considerable cost savings because modern cars necessitate more and more routine service and are made up of more and more technical components that result in new breakdowns or inconveniences. One of the complications that affects more and more Audi S5 owners is a clogged air flow meter, which will result in a loss of power and black exhaust gases. In this article we are going to take a look at how to clean the mass air flow sensor of your Audi S5? . First, we will explain how your mass airflow sensor functions and its usefulness, second, why it may be important to clean this sensor , and at last, how to clean the mass air flow sensor of a Audi S5 .

Utility and operation of the mass air flow meter of a Audi S5

.
So we begin our content page with the operation and role of your Audi S5 flowmeter.

The goal of the mass air flow sensor on Audi S5

The mass air flow sensor is a part that has been developed actually quite not too long ago and principally outfitted on diesel models. Obviously, with injection engines, the fuel and air intake has become very precise and it is therefore important for the ECU to know the exact volume of air injected into the engine to modify the behaviour of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Audi S5, do not hesitate to consult our content page on this subject.

Mass air flow sensor operation on Audi S5

  • Once taken apart, you will have the ability to move forward to the step cleaning the mass air flow sensor of your Audi S5 . 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 affect the operation of the engine of your Audi S5. The goal of this cleaning will be to remove all its harmful particles 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 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 broken. 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 also 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 Audi S5 , you should feel a noticeable difference in the behavior of your engine.
