My engine makes whistling noise just before the gear shifts around 2000 RPM.
This issue was there since day 1. It has been around 2 years already.
I brought it in to the dealers 4 times, and they couldn't find the problem.
Today they made a conclusion that this is normal, because they have 3 other cars reported with the same problem.
Should I give up and just live with it?
Or should I do something with BMW North America?..
For your information, here is the sound clip:

PS. I have N55 engine.
