More and more car owners are trying to maintain their cars by themselves. This results in substantial savings because modern cars require more and more maintenance and are done up of more and more technical components that result in new breakdowns or inconveniences. One of the problems that disturbs more and more Volkswagen New Beetle owners is a clogged air flow meter, which will lead to a loss of power and black exhaust fumes. Today we are going to examine how to clean the mass air flow sensor of your Volkswagen New Beetle? . First, we will teach you how your mass airflow sensor functions and its usefulness, second, why it might be important to clean this sensor , and finally, how to clean the mass air flow sensor of a Volkswagen New Beetle .

Utility and operation of the mass air flow meter of a Volkswagen New Beetle

.
So we start our article with the procedure and role of your Volkswagen New Beetle flowmeter.

The intent of the mass air flow sensor on Volkswagen New Beetle

The mass air flow sensor is a part that has been created actually quite lately and principally supplied on diesel models. In fact, 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 added into the engine to modify the actions of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Volkswagen New Beetle, do not think twice to consult our article on this subject.

Mass air flow sensor operation on Volkswagen New Beetle

Now, we are going to have a look at how it functions, before trying to clean the mass air flow sensor of your Volkswagen New Beetle , you must already understand how it works to achieve this maintenance action properly.

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 mounted just after the air intake of your Volkswagen New Beetle, i. e. just after the air filter. It is a pipe supplied with a sensor that will review the air in the intake and transmit the info to the ECU of your car.

Why clean the mass air flow sensor of a Volkswagen New Beetle?

The mass air flow sensor of your Volkswagen New Beetle can have problems and this is what we will try to find out and figure out what problems you might be struggling with!

Mass air flow sensor problems Volkswagen New Beetle

Here are the different problems that the air flow sensor of your Volkswagen New Beetle can generate:

How do I clean the mass air flow sensor from a Volkswagen New Beetle?

After examining the operation and problems that the flowmeter can generate, we will look at how to solve these problems by showing to you how to clean the mass air flow sensor of your Volkswagen New Beetle . You should know that this process is actually quite basic to conduct and you will not need advanced mechanical skills to do it your self, a good method to avoid a trip to the mechanic and a steep bill. See below the different steps to stick to to conduct this maintenance act:

  • Once disassembled, you will have the ability to continue to the step cleaning the mass air flow sensor of your Volkswagen New Beetle . 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 have the ability to collect data properly, it is in this sense that it will disturb the operation of the engine of your Volkswagen New Beetle. The intent of this cleaning will be to remove all its impurities 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 delicate cleaning of the flow meter filaments. You have to be very cautious, 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 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 Volkswagen New Beetle , you should feel a noticeable difference in the behavior of your engine.
