[VanGemma]

Mercedes-Benz Vito middle door squeaking noise causes are as follows: Foreign objects: There are small items inside the door trim panel, such as lighters, coins, or other objects. Loose trim panel: The trim panel or audio system has become loose. This issue can be identified by simply shaking the panel by hand or pressing on the noisy area while driving. If the noise stops, it confirms the issue, and tightening the components will resolve it. Hinge rust: The door hinges (pivots) have rusted. This condition is usually noticeable when opening or closing the door. The solution involves cleaning the hinges and applying some grease.
