What are the reasons for the loud noise in BMW X3?

The following are the reasons for the loud noise in BMW X3: 1. Poor door sound insulation: The first step is the door sound insulation treatment, which mainly aims to reduce the wind noise of BMW X3. Remove the door panel accessories to check the original door's sound insulation treatment. There is a layer of damping plate, which is thicker than that of other models; however, the sound insulation materials used in the original car are relatively ordinary, and the sound insulation effect still needs improvement. 2. Poor original sound insulation materials of the car body: Choose to paste automotive sound insulation materials with better damping effects, otherwise the noise will be very loud. It effectively enhances the solidity of the metal sheet, avoids the resonance phenomenon of the metal sheet, and effectively reduces wind noise intrusion. After double-layer sound insulation treatment of the front and rear doors, the wind noise will be significantly reduced. 2. Poor cabin floor sound insulation: Next is the cabin floor sound insulation, mainly to reduce road noise and chassis resonance noise. Remove the seats, carpets, and other accessories. This is the original chassis structure of BMW X3. The original car's sound insulation treatment is still relatively minimal.
Last time I drove a BMW X3, the noise was so loud it felt like driving a tractor! The most common issue is tire problems - severe wear from age or incorrect tire pressure causing a humming sound at high speeds. Wheel bearings may also be aging, producing squeaky noises when rotating. On the engine side, a loose or cracked belt makes whining sounds during acceleration, while exhaust system leaks create sharp hissing noises. Wind noise can be significant too, with aged door seals letting in air like whistles. Worn suspension bushings make clunking sounds on bumpy roads, ruining the driving experience. I recommend checking these first - inspect tire pressure and wear yourself, or visit a 4S shop for professional help. Regular maintenance is crucial; don't wait until noise becomes severe as it poses safety risks and distracts you on the road.
