Does anyone else get a strange noise
I'm wondering if that is a normal sound and if not, might it be fixed under factory warranty?
I'm a sound guy by trade and noises drive me bonkers.

Stock parts, where the bov would be installed:
Bov(in red) installed in between those 2 parts (on a different MB engine):
since my car got a tune, i've the owl noise too. I thought it might be a pressure release from the turbos?
Hope we get some more information about this.

No other car sounds so much like there’s an owl trapped under the bonnet when you back off the accelerator – a slight but distinct hoo-hoo (or possibly even woohoo! as it seems to be having a good time) that never ceased making us smile. You don’t get so much of this in the regular model, which probably tells you where AMG found those extra horses.

I'll be damned. So it's normal. Thanks for posting that, I can live with it if it's not an anomaly.
Orc, I'll try to capture the sound for you and post it.
We are part of the owl club Andreas. On my car I had the sound before the tune, after the tune it was amplified 5 times. It happens almost every time I release the throttle now, including a new sound like a loud short whistle for an instant right at the release point. Almost like the tires screeching for a half second.
