More and more drivers are trying to take care of their cars on their own. This results in significant cost savings because contemporary cars necessitate 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 Bmw Serie 3 owners is a clogged air flow meter, which will lead to a loss of power and black exhaust gases. Today we are going to look at how to clean the mass air flow sensor of your Bmw Serie 3? . First, we will describe how your mass airflow sensor works 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 Bmw Serie 3 .
Utility and action of the mass air flow meter of a Bmw Serie 3
.
So we begin our content with the procedure and role of your Bmw Serie 3 flowmeter.
The goal of the mass air flow sensor on Bmw Serie 3
The mass air flow sensor is a part that has been developed actually quite lately and principally equipped on diesel models. Obviously, with injection engines, the fuel and air intake has become very precise and it is consequently necessary for the ECU to know the exact volume of air added 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 Bmw Serie 3, do not hesitate to consult our content on this subject.
Mass air flow sensor operation on Bmw Serie 3
Now, we are going to look at how it works, before trying to clean the mass air flow sensor of your Bmw Serie 3 , you must already figure out how it functions to do this maintenance work accurately.
The mass air flow sensor is therefore principally there to get info on the air intake of your motor vehicle. To get this done, it must be set up just after the air intake of your Bmw Serie 3, i. e. just after the air filter. It is a pipe equipped with a sensor that will review the air in the intake and transfer the info to the ECU of your car.
Why clean the mass air flow sensor of a Bmw Serie 3?
The mass air flow sensor of your Bmw Serie 3 can have problems and this is what we will try to find out and figure out what problems you may be struggling with!
Mass air flow sensor problems Bmw Serie 3
Here are the different problems that the air flow sensor of your Bmw Serie 3 can provoke:
- higher fuel consumption: Because a dirty flow meter will necessarily result in excessive fuel consumption due to poor air flow…
- Power loss: Associated with similar issue, this lack of air can provoke a loss of power to your engine.
- Difficulties starting the vehicle: Finally, one of the last traditional problems associated with a dirty flowmeter will be that your Bmw Serie 3 will have more troubles to begin the vehicle.
How do I clean the mass air flow sensor from a Bmw Serie 3?
After reviewing the operation and problems that the flowmeter can provoke, we will look at how to fix these problems by showing to you how to clean the mass air flow sensor of your Bmw Serie 3 . You should know that this process is actually quite simple to perform and you will not need advanced mechanical skills to do it yourself, a good technique to avoid a trip to the garage and a steep bill. See down below the different steps to stick to to perform this maintenance act:
- After having found the mass air flow sensor of your Bmw Serie 3 , you will have to dismantle it. To get this done, work gently, but you will just have to disassemble it on both sides of the air duct and disconnect the electrical plug on top of it.
- Once taken apart, you will be able to proceed to the step cleaning the mass air flow sensor of your Bmw Serie 3 . 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 be able to collect data accurately, it is in this sense that it will disturb the operation of the engine of your Bmw Serie 3. The goal of this cleaning will be to take out all its impure substances 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 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 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 damaging 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 Bmw Serie 3 , you should feel a noticeable difference in the behavior of your engine.
