I am looking for any suggestion in this topic because I had this problem from last few months and it's so so annoying.
Please refer this video and listen:
https://www.dropbox.com/s/lj8b9nguwm...speed.mov?dl=0
Does anyone have an idea what may be to blame - this is the sound I hear (snapping) at speeds above 170-180 km / h.
Additionally, you can usually hear the same sound on the road in villages near cities where the road is uneven or made of bricks.
The authorized service center recognizes that there is no problem - and it does not want to perform the test at the speed specified above - and I have not been able to find a similarly bad road near the service centers.
any suggestion appreciated.
PS: in the same time I had "clean" interior. nothing in cupholder etc.
