More and more car owners are trying to take care of their vehicles on their own. This outcomes in significant cost savings because modern cars involve more and more maintenance and are done up of more and more technical components that lead to new breakdowns or inconveniences. One of the problems that impacts more and more Bmw Serie 7 owners is a clogged air flow meter, which will end in a loss of power and black exhaust fumes. In this article we are going to take a look at how to clean the mass air flow sensor of your Bmw Serie 7? . First, we will show you how your mass airflow sensor operates and its value, 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 7 .

Utility and action of the mass air flow meter of a Bmw Serie 7

.
So we begin our content page with the process and purpose of your Bmw Serie 7 flowmeter.

The purpose of the mass air flow sensor on Bmw Serie 7

The mass air flow sensor is a component that has been developed 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 important 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 7, do not think twice to consult our content page on this subject.

Mass air flow sensor operation on Bmw Serie 7

  • Once disassembled, you will be able to continue to the step cleaning the mass air flow sensor of your Bmw Serie 7 . 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 disrupt the operation of the engine unit of your Bmw Serie 7. 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 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 destroying it, you can as well clean them with a brake fluid in the form of an aerosol by spraying the jet on these filaments.
