How to Replace the Mass Airflow Sensor on Mercedes C-Class - W203

Model: Mercedes Classe C W203 - Years 2000-2007
Part: MAF sensor

Remove the upper engine cover, which is divided into two parts, and clean it with an air compressor. Now you will see the mass airflow sensor in front of you. Disconnect the connector from it (it has two small side levers that need to be pressed). Next, remove the retaining clips of the mass airflow sensor and replace it with the new one, as shown in the video, simply pushing it into place and reinstalling the retaining ring. Apply a treatment product to the connector of the mass airflow sensor. Finally, reinstall the air intake hoses.
