Hi, I just bought this 2011 BMW 528i and I noticed that there is a chirping noise when I start driving it in the morning over minor regular street bumps. When I progressively continue to drive it throughout the day the noise seems to disappear so every time I go to the dealer they cant figure it out because the noise is hard to reproduce. They told me since it happens mainly in the morning to leave it over night. I wanted to know what you guys think and if any of you guys here experienced this annoying issue. This is my first BMW and I'm not too thrilled about this annoying issue. The car only has 53K miles on it. I inserted a video of the problem and you can see its regular residential blocks. Thank you in advance!
