Loud whine noise on hard acceleration
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 |

Sounds like it is time for a trip to the dealer. My 28i certainly doesn't make any unusual loud noises upon acceleration, only the expected turbo whine...but that isn't loud by any stretch.
Good luck!

With my windows up I can hardly hear my turbo, but when they're down that's all I can hear. This car makes a lot of turbo noise. I do however hear my heater fan whine while I drive around. I just turn my radio up louder.
Try driving around with your climate control completely off, if the whine goes away, viola!

The whine begins from hard acceleration, during wide open throttle. Otherwise if I am lite on the pedal, I can hear the turbo whine like it should with no other loud sound. I am not sure if I have a vacuum leak. I think it may be a faulty diverter valve.
