The sunroof drain pipe is located in the B-pillar, and if the fixing clip cannot secure or fails to hold the drain pipe in place, it will produce abnormal noise during driving. Below are the specific details: 1. Replacing the clip: The drain pipe fixing clip needs to be re-secured. The interior components on the B-pillar are fixed in position using clips and fixing components. When the fixing clip lacks sufficient tension or is missing, it will cause abnormal noise. This requires replacing the clip to resolve the issue. 2. Interior components: For two adjacent interior components on the B-pillar, when driving or on bumpy roads, displacement of the parts and material properties can lead to abnormal noise. Generally, this can only be resolved by securing the parts, applying noise-proofing treatments, or replacing the components.
Common causes of Atz's abnormal noises are aging or loose suspension systems, such as leaking shock absorbers, loose suspension arm screws, which cause squeaking when going over speed bumps. I often drive this car and find that when the chassis components are severely worn, the noise becomes more obvious. For self-inspection, you can first lift the car to check for loose parts, but it's best to consult a professional mechanic—safety first. Regular maintenance of the car's suspension is crucial; early detection and repair can prevent risks when driving at high speeds. If suspension issues are not resolved, driving feels unstable, affecting handling and even being frightening. After daily use, pay attention to changes in abnormal noises and record when they occur to ensure more accurate diagnosis.
