Question for 4.8is owners EDIT: problem fixed

EDIT: My dealer finally located the source of the whine coming from my engine

During my 2nd service appointment yesterday, my local dealer discovered that the whining sound was coming from my alternator. With the new one installed, all I hear is the wonderful exhaust note.

I hope someone finds this helpful.

Just wondering if fellow 4.8is owners hear a whining sound when driving around with the windows down. The whine is more prominent at higher RPMs or in Sport mode.

Local BMW dealer first thought that it was the transmission. However, after conferring with BMW they were informed that this engine has a whine to it.

Local dealer took off the belt and the whine went away. Once re-installed, the whine is back.

Thanks in advance for your feedback.
