More and more drivers are trying to take care of their cars by themselves. This results in considerable cost savings because contemporary cars require more and more routine service and are done up of more and more technical components that result in new breakdowns or inconveniences. One of the complications that impacts more and more Volkswagen Polo 3 owners is a clogged air flow meter, which will lead to a loss of power and black exhaust fumes. In this article we are going to examine how to clean the mass air flow sensor of your Volkswagen Polo 3? . First, we will explain how your mass airflow sensor functions and its advantages, second, why it may be relevant to clean this sensor , and at last, how to clean the mass air flow sensor of a Volkswagen Polo 3 .
Utility and operation of the mass air flow meter of a Volkswagen Polo 3
.
So we start our content with the operation and point of your Volkswagen Polo 3 flowmeter.
The purpose of the mass air flow sensor on Volkswagen Polo 3
The mass air flow sensor is a part that has been developed actually quite lately and specifically supplied on diesel models. In truth, 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 injected into the engine to adapt the behaviour of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Volkswagen Polo 3, do not think twice to consult our content on this subject.

The purpose of this cleaning will be to remove all its impure substances 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 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 watchful, otherwise 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 as well clean them with a brake fluid in the form of an aerosol by spraying the jet on these filaments.
.
