The solution to the rattling noise from the right rear door of Audi A4L on bumpy roads is: replace the trim strip, add double-sided tape to the clips, and remove and refix the interior trim panel near the door frame. Taking the 2020 Audi A4L 35TFSI Fashion Dynamic model as an example: it is a mid-size 4-door 5-seater sedan with a length, width, and height of 4858mm, 1847mm, and 1439mm respectively, a wheelbase of 2908mm, and front-wheel drive. In terms of power, this car uses a 2.0T inline 4-cylinder engine with a maximum power of 110 kW and a maximum torque of 270 N·m, paired with a 7-speed dual-clutch transmission.
I think the abnormal noise from the right rear door of the Audi A4L on bumpy roads may stem from several common issues. Worn hinges can produce creaking sounds, especially on uneven surfaces. A loose or rusty door lock mechanism can cause rattling noises when vibrating. Aging or loose sealing strips may also lead to friction sounds. Another possibility is loose clips inside the interior panel, causing internal components to shake during bumps. I've tried checking it myself: opening the door, shaking the door panel to identify loose parts, then applying some lubricant or tightening screws. If the noise persists, it might be due to damaged internal components like brackets, requiring professional technicians with diagnostic tools for inspection. For safety, it's advisable to have door components lubricated during regular maintenance to prevent this issue, avoiding worsening noises that could affect the driving experience.
