More and more motorists are trying to take care of their cars by themselves. This outcomes in considerable savings because modern cars require more and more routine service and are done up of more and more technical parts that lead to new breakdowns or inconveniences. One of the problems that disturbs more and more Audi E-Tron owners is a clogged air flow meter, which will result in a loss of power and black exhaust fumes. Today we are going to look at how to clean the mass air flow sensor of your Audi E-Tron? . First, we will show you how your mass airflow sensor functions and its advantages, second, why it might be important to clean this sensor , and at last, how to clean the mass air flow sensor of a Audi E-Tron .
Utility and operation of the mass air flow meter of a Audi E-Tron
.
So we begin our article with the process and purpose of your Audi E-Tron flowmeter.
The goal of the mass air flow sensor on Audi E-Tron
The mass air flow sensor is a component that has been developed actually quite lately and principally outfitted on diesel models. In actual fact, with injection engines, the fuel and air intake has become very precise and it is consequently essential 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 Audi E-Tron, do not think twice to seek advice from our article on this subject.
Mass air flow sensor operation on Audi E-Tron
Now, we are going to have a look at how it functions, before trying to clean the mass air flow sensor of your Audi E-Tron , you must already understand how it functions to do this routine service action properly.
The mass air flow sensor is therefore principally there to get statistics on the air intake of your motor vehicle. To get this done, it must be mounted just after the air intake of your Audi E-Tron, i. e. just after the air filter. It is a pipe outfitted with a sensor that will review the air in the intake and transfer the statistics to the ECU of your car.
Why clean the mass air flow sensor of a Audi E-Tron?
The mass air flow sensor of your Audi E-Tron can have problems and this is what we will try to find out and discover what problems you might be struggling with!
Mass air flow sensor problems Audi E-Tron
Here are the different problems that the air flow sensor of your Audi E-Tron can trigger:
- higher fuel consumption: Because a dirty flow meter will necessarily lead to more significant fuel consumption because of poor air flow…
- Power loss: Linked to similar issue, this lack of air can trigger a loss of power to your engine.

How do I clean the mass air flow sensor from a Audi E-Tron?
After examining the operation and complications that the flowmeter can trigger, we will look at how to solve these problems by describing to you how to clean the mass air flow sensor of your Audi E-Tron . You should know that this process is actually quite basic to conduct and you will not need advanced mechanical skills to do it yourself, a good method to avoid a trip to the garage area and a steep bill. Discover below the different steps to stick to to conduct this routine service act:

- Once taken apart, you will be able to proceed to the step cleaning the mass air flow sensor of your Audi E-Tron . 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 be able to collect data properly, it is in this sense that it will disturb the operation of the engine unit of your Audi E-Tron. The goal of this cleaning will be to take out 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 take out most of the grime
- Now we’ll proceed 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 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 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 E-Tron , you should feel a noticeable difference in the behavior of your engine unit.
