What Causes the Abnormal Noise in Mercedes-Benz E300L on Bumpy Roads?

[StAlivia]

Over time, gaps may develop between some parts of the car body, leading to friction among certain components when driving on unpaved roads or during emergency braking, which results in abnormal noise. Below are solutions for the abnormal noise: 1. Body Noise: For body noise, it is recommended to visit a 4S shop to check the tightness of chassis screws and connectors, and inspect whether any parts of the body are rubbing against each other. 2. Window Noise: If the window makes abnormal noise, roll down the glass, clean the rubber sealing strips around the door frame, and use a damp cloth to wipe between the two rubber strips until the dust is removed, which can basically eliminate the noise.
