Also, when I checked under the hood, it was extremely hot. 1. If anyone has any idea of what might be the issue, and 2. Im worried if I take it in, BMW will void my warranty. Any help would be greatly appreciated. Thanks!
Sounds like it could be charge pipe, just happened to me and all the symptoms seem to be very similar.
