What are the causes of the sunroof rattling noise in the C200 Coupe?
1 Answers
Here are the reasons for the sunroof rattling noise: 1. Aging of rubber seals or gaskets: The sunroof sealing rubber strips are exposed to rain or intense sunlight for long periods, making them prone to aging. Rubber conditioner can temporarily restore the performance of the seals, but severely aged seals require replacement. 2. Loose screws: Loose screws can cause rattling noises from the headliner and sunroof, and may even pose a risk of the sunroof detaching. The solution is to tighten the sunroof screws. 3. Dust particles in the sliding rails: Dust tends to accumulate in the gaps of the sunroof sliding rails. When enough dust builds up, friction occurs during sunroof operation, leading to rattling noises. The dust can be removed with a cloth.
