How to Locate the Root Cause of Q5 Sunroof Abnormal Noise?

[OJeremiah]

The causes of Q5 sunroof abnormal noise are: 1. Noise when stationary, indicating loose components near the sunroof or substandard sealing parts; 2. Noise when opening, pointing to issues with the lifting mechanism; 3. Prolonged usage inevitably leads to debris particles on the sliding rails. When the sunroof moves along these rails, it rubs against the debris, causing abnormal noise. Therefore, maintaining clean sliding rails is essential. Apply lubricating grease to the noisy areas, ensuring thorough application at the friction-prone spots. Carefully spread the grease evenly on both sides of the sunroof and precisely within the sliding rails, avoiding external application.
