Investing in a luxury vehicle is a choice many auto owners make. Whether appreciating the style of the vehicle, the reliability of the brand, or simply enjoying the features a high-end vehicle offers – there are many reasons why people choose a Mercedes Benz.
As with any vehicle, there are different issues that can arise. With Mercedes, an oddly common concern is the mass airflow malfunctioning. Which Euro Fix would like to explain ‘Why Your Mercedes Mass Air Flow Malfunctions’ – and offer our help to maintain or fix it!
First of All – What is a Mass Air Flow Sensor?
As described via Wikipedia: “A mass flow sensor is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure.”
Why is a Mass Air Flow Sensor Important?
As it pertains to your Mercedes, your mass air flow sensor measures the temperature of air, as well as the quantity of air coming in. This is communicated to your vehicles computer to help your fuel injection system function optimally.
As mentioned above, your mass air flow sensor mixes an appropriate ratio of fuel to air in order for ignition and combustion levels to perform, which a Mercedes owner would expect regardless of climate or driving conditions
Why Do Mass Air Flow Sensors Fail in a Mercedes?
As with any vehicle or part therein, mass air flow sensors wear out over time.
The routine maintenance of your Mercedes can address this with cleaning to an extent, but over time – it will be necessary to replace to function at its best.
Without addressing the issue, your will notice your vehicle will change in how it operates, and your computer system will likely translate this information during an inspection.
In addition, your ‘check engine light’ sensor will be triggered if left too long, with noticeable hesitation in acceleration, strange idling or stalling, and even the failure to start your vehicle.
Whether your drive a Mercedes Benz or any other European model vehicle, having your air flow sensor checked and/or replaced is an important part to your maintenance schedule. This is something Euro Fix is happy to help you with, addressing any other additional issues you might have, while ensuring you drive away confident in the performance, function and safety of your Mercedes Benz!
