Golf 7 After the sunroof assembly was replaced, the front sun visor of the driver's seat and the passenger's seat made abnormal noise on the lame road. What's going on here?

With the popularity of automobile skylights, abnormal sound of skylights is also exposed in large quantities. At present, the most authoritative explanation is as follows:

1. Aging of skylight sealing rubber leads to increased gap and abnormal sound. The solution is to replace the sealing strip.

Second, foreign objects such as sand enter the skylight slide rail. There is an abnormal noise when it bumps. Solution: Clean the foreign matter on the slide rail and lubricate it properly.

Thirdly, for panoramic sunroof, the car body will be deformed after a certain number of years. The skylight material is different from the car body, and the displacement degree of deformation is different, so abnormal noise is generated. At present, cars equipped with panoramic front windows have more or less such problems. There is no good solution.

So, please check your car according to the above tips.
