What Causes the Acceleration Noise in the Rear Seats of a BMW 3 Series?
1 Answers
BMW 3 Series acceleration noise in the rear seats can be attributed to the following reasons: Body Noise: This issue is usually caused by insufficient body rigidity, leading to deformation during driving, resulting in friction or shaking between the doors and door frames, or even loose welds causing friction between metal plates. Applying adhesive strips on the windows or placing rubber pads at friction points may reduce or eliminate the noise, but these are temporary fixes. Additionally, poorly secured body components can also cause noise, which can often be resolved by tightening screws. Suspension Noise: If you hear thumping or cracking sounds near the wheels when driving over bumps, it is likely due to shock absorber issues or loose suspension components. It is crucial to have this inspected at a professional repair shop, as suspension components not only affect ride comfort but also impact driving safety. Never overlook this issue.
