What causes the shock absorber noise in Mercedes-Benz E-Class?

[TannerAnn]

Due to the structure of the shock absorbers in Mercedes-Benz E-Class vehicles, the entire shock absorber gets compressed when the vehicle passes over bumpy roads, thereby compressing the external spring. However, after the vehicle passes the bumpy section, the spring's elasticity causes the shock absorber to reset. During this compression and reset process of the shock absorber, a "hissing" or "whooshing" exhaust sound may accompany the movement. Here is some relevant information: Normal condition: Therefore, there's no need to panic when you hear "hissing" or "whooshing" sounds from the shock absorbers while driving on bumpy roads—these are normal occurrences. Mercedes-Benz E-Class shock absorbers: Every vehicle must bear the weight of the vehicle itself and its passengers while also reducing road bumps during this process.
