What is the solution for the Volkswagen CC sunroof rattling noise?

[DiJoanna]

Volkswagen CC sunroof rattling noise may be caused by friction between the sunroof and the roller shade metal parts. Applying some grease or sticking tape on the friction areas of both the sunroof and roller shade metal parts can eliminate the noise. Here is some related information: 1. The Volkswagen CC is equipped with an electric sunroof, measuring 420mm in length and 740mm in width, with a daylighting area of approximately 0.31 square meters. Although it is not a panoramic sunroof, it is fully sufficient for daylighting and ventilation. 2. The sunroof can be opened upwards. When the weather is good, opening the sunroof for ventilation prevents direct wind exposure. The Volkswagen CC's sunroof is quite distinctive, designed as a half-roof sunroof based on the vehicle's styling. The front half of the entire roof is a large glass sunroof. Due to the Volkswagen CC's inherently low vehicle height design, there is no space in the roof to accommodate the sunroof track, so only the front half can be opened, while the rear half cannot. If forcibly opened, the sunroof would hit the head of rear passengers.
