The solution for the buzzing sound in the Lavida engine is: 1. Remove the sound insulation cotton, then apply foam adhesive and also apply a layer around the sound insulation cotton, reinstall the sound insulation cotton, and secure it with screws; 2. Add adhesive under all screw washers to make the screws more secure and less prone to loosening; 3. Use adhesive to fix any gaps between the sound insulation cotton and the decorative cover.
