My son was seating on the arm rest and suddenly I applied the breaks. He couldn't hold and damn he broke the rear view mirror. He was ok but I found it so difficult to fix it and for a moment I thought that have to visit the garage. Thanks to ur video I now know how to fix it. Going to give it a try tmro morning.
I also face the same problem in W8 it's becz of the rubber covering on the lower side where the seat belt was fixed . I changed it from authorised service center under warrenty after sending a mail to the official customer care it's called the seat Balancer part . The black rubber covering make the irrigating sound if your warranty has been expired just put some dashboard polish inside the rubber area it's also make it quit for 2-3 month
