Turbo Noise at High RPM on 40i
So I’ve been gradually increasing the RPM’s now I’ve got more miles on my X5. Today I was in sport mode and for the first time had the front windows down during some more ‘rapid’ driving I could hear quite a bit of turbo whine at high RPM, not sure what I think about it. Never heard that sort of think on my 40d F15 and that had more turbos!
Anybody else hear the same? I should say I can only hear it with the front windows open though. |

Exactly the same for me. Never heard it with windows up, but it's noticeable if the windows are down. By comparison, our F150's turbos are audible even with the windows rolled up.
