Engine "Chirp" on initial acceleration - what is it?

When first accelerating, I hear a slight chirp from the engine - it is not the tires. Any ideas? If it is not normal, I wonder if a belt is slipping slightly.

Thanks in advance.

Do a search on this forum for "supercharger chirp" -- many people have it. You will also find a "fix" for it, although I've never tried it.

Its pretty normal. Mine has it. Considering how quiet the E55 is, I think its kinda cool. Reminds me the supercharger is there.

just leave it as is... I think the most important thing you should worry about is if you dont' have it or hear it... from what i know, heard, read about, it's normal!

Its The Supercharger Clutch Engaging. You Can Shim The Clutch And The Noise Will Go Away For A While But It Will Come Back.

It Is Now Considered Normal And We Are Not Supposed To Shim It Anymore.

You may want to check out your engine bay thouroughly man. When I had the chirp, I inspected my bay, and it had a nest of sparrows living in there. It was crazy.

Emoving, contact mods about making your thread a sticky please.
