When driving my 88M3 I hear an electric sound that reminds me of a dentists drill. The pitch rises with the rpms. When I turn on the radio it's even more pronounced. Does anyone have any ideas on what might cause this?

Had the same problem. My stereo ground wire was touching part of the exposed power antenna plug. Once I insulated both, the whine went away.
