More and more car owners are trying to maintain their vehicles on their own. This results in substantial cost savings because contemporary cars require more and more routine service and are done up of more and more technical parts that result in new breakdowns or inconveniences. One of the complications that impacts more and more Audi Q8 owners is a clogged air flow meter, which will bring about a loss of power and black exhaust gases. Today we are going to take a look at how to clean the mass air flow sensor of your Audi Q8? . First, we will describe how your mass airflow sensor works and its usefulness, second, why it may be relevant to clean this sensor , and at last, how to clean the mass air flow sensor of a Audi Q8 .

Utility and action of the mass air flow meter of a Audi Q8

.
So we start our article with the procedure and aim of your Audi Q8 flowmeter.

The intent of the mass air flow sensor on Audi Q8

The mass air flow sensor is a component that has been developed actually quite lately 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 Audi Q8, do not think twice to consult our article on this subject.

The intent of this cleaning will be to remove all its impure substances to allow 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 careful, in any other case 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 destroying 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 Q8 , you should feel a noticeable difference in the behavior of your engine unit.
