How to Deal with Constant Buzzing Sound in Mercedes-Benz E300 Cabin?
1 Answers
The solution to the constant buzzing sound in the Mercedes-Benz E300 cabin is: Check the intake path, from the air intake to the throttle valve, to see if there are any loose components or foreign objects. The throttle valve is the throat of the engine, controlling the engine's air intake. When the driver presses the accelerator pedal, it does not directly control the fuel injection but rather the throttle valve's opening. Taking the Mercedes-Benz E-Class 2021 facelift E300L Fashion model as an example: Its dimensions are 5078mm in length, 1860mm in width, and 1480mm in height, with a wheelbase of 3079mm, equipped with a 9-speed automatic transmission.
