This results in substantial cost savings because contemporary cars require more and more routine service and are made up of more and more technical parts that lead to new breakdowns or inconveniences. One of the complications that disturbs more and more BMW X5 owners is a clogged air flow meter, which will bring about a loss of power and black exhaust fumes. Today we are going to take a look at how to clean the mass air flow sensor of your BMW X5? . First, we will describe how your mass airflow sensor functions 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 X5 .
Utility and operation of the mass air flow meter of a BMW X5
.
So we begin our article with the process and aim of your BMW X5 flowmeter.
The intent of the mass air flow sensor on BMW X5
The mass air flow sensor is a part that has been created quite recently and principally outfitted 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 loaded into the engine to adapt the actions of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your BMW X5, do not think twice to consult our article on this subject.
