More and more drivers are trying to take care of their cars on their own. This outcomes in significant savings because modern cars require more and more maintenance and are done up of more and more technical parts that lead to new breakdowns or inconveniences. One of the problems that impacts more and more Audi A5 owners is a clogged air flow meter, which will result 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 Audi A5? . First, we will describe how your mass airflow sensor functions and its advantages, second, why it may be important to clean this sensor , and finally, how to clean the mass air flow sensor of a Audi A5 .

Utility and operation of the mass air flow meter of a Audi A5

.
So we start our content with the operation and aim of your Audi A5 flowmeter.

The intent of the mass air flow sensor on Audi A5

The mass air flow sensor is a part that has been developed quite not long ago and specifically outfitted on diesel models. Indeed, with injection engines, the fuel and air intake has become very precise and it is so necessary for the ECU to know the exact volume of air loaded 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 Audi A5, do not hesitate to consult our content on this subject.

Mass air flow sensor operation on Audi A5

The intent of this cleaning will be to take out 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 take out most of the grime
  • .

  • Now we’ll proceed to the very gentle cleaning of the flow meter filaments. You have to be very cautious, in any other case your mass air flow sensor will be permanently broken. 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 Audi A5 , you should feel a noticeable difference in the behavior of your engine.
