More and more motorists are trying to maintain their vehicles on their own. This results in considerable savings because contemporary cars involve more and more routine service and are done up of more and more technical components that lead to new breakdowns or inconveniences. One of the complications that affects more and more Bmw Z4 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 Z4? . First, we will explain how your mass airflow sensor functions and its advantages, second, why it may be important to clean this sensor , and at last, how to clean the mass air flow sensor of a Bmw Z4 .

Utility and operation of the mass air flow meter of a Bmw Z4

.
So we start our article with the process and goal of your Bmw Z4 flowmeter.

The goal of the mass air flow sensor on Bmw Z4

The mass air flow sensor is a part that has been created quite not too long ago and specifically equipped on diesel models. Obviously, with injection engines, the fuel and air intake has become very precise and it is so essential 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 Bmw Z4, do not think twice to seek advice from our article on this subject.

Mass air flow sensor operation on Bmw Z4

Now, we are going to check out how it functions, before trying to clean the mass air flow sensor of your Bmw Z4 , you must already figure out how it works to achieve this routine service act properly.

The mass air flow sensor is consequently specifically there to obtain data on the air intake of your car. To achieve this, it must be set up just after the air intake of your Bmw Z4, i. e. just after the air filter. It is a pipe equipped with a sensor that will analyze the air in the intake and transmit the data to the ECU of your car.

Why clean the mass air flow sensor of a Bmw Z4?

The mass air flow sensor of your Bmw Z4 can have complications and this is what we will try to discover and figure out what complications you may be facing!

Mass air flow sensor complications Bmw Z4

Here are the different complications that the air flow sensor of your Bmw Z4 can cause:

  • higher fuel consumption: Because a dirty flow meter will actually end in higher fuel consumption caused by poor air flow…
  • Power loss: Associated with similar issue, this lack of air can cause a loss of power to your engine.

How do I clean the mass air flow sensor from a Bmw Z4?

After examining the operation and problems that the flowmeter can cause, we will look at how to solve these complications by describing to you how to clean the mass air flow sensor of your Bmw Z4 . You should know that this procedure is quite simple to accomplish and you will not need advanced mechanical skills to do it yourself, a good method to avoid a trip to the workshop and a steep bill. Discover below the different steps to stick to to accomplish this routine service act:

  • After having based the mass air flow sensor of your Bmw Z4 , you will have to dismantle it. To achieve this, act delicately, but you will just have to disassemble it on both sides of the air duct and detach the electrical plug on top of it.
  • Once disassembled, you will be able to move forward to the step cleaning the mass air flow sensor of your Bmw Z4 . This sensor will, as time passes, 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 properly, it is in this sense that it will disturb the operation of the engine unit of your Bmw Z4. The goal of this cleaning will be to remove all its harmful particles to allow 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 gentle cleaning of the flow meter filaments. You have to be very watchful, in any other case your mass air flow sensor will be permanently broken. With the help of a fine brush and solvent, delicately clean the two filaments of your mass air flow sensor . If you are too afraid of destroying 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 Z4 , you should feel a noticeable difference in the behavior of your engine unit.
