Hi everyone,

I am still new to the threads but have been enjoying being part of the X1 community.

On hard acceleration my car is starting to make a really loud whine, kind of like a supercharger. I don't believe that is the turbo whine since I can still hear the the turbo spool. I am kind of leading towards a vacuum leak but when I bought it to my dealer they said it was turbo whine. This though is really loud.

Any one ever experience this issue?

Thanks for you help.

Lu
