Please HELP!!! Need to identify to find out if this noise is normal. THANKS!
I have a new C63s AMG, my car is making this weird owl whooting noise when i steer left and accelerate slightly harder than normal driving. I have included the link below, it's between 4-5th second you can hear the noise. I brought it back to dealer and for 2 weeks they can't find anything wrong with the car. and said that's normal and it's just BOV. anyone has the same noise when they speed up C63s?

just the other day I was bamboozled by a new rattle in my car and only after a couple of hours figured out it was my sunglasses rattling away in the sunglass compartment next to the rear view mirror .

IMO not exactly. I hear it when I accelerate hard in say second and then when it switches to 3 I’m still accelerating but I have let off a bit - not lifted- as though the ecu is expecting hard acceleration but it turns into mild acceleration. That’s when I hear it. I almost never hear the hoot when I lift.
I came across this old thread today while searching for something else, and wanted to comment. I have experienced the same thingas OP, and I assume it is the traction control releasing air boost from the intake tract do when turning due to loss of traction. Basically I think the traction control or stability control is opening the blowoff valve in order to reduce power as part of doing its job. If you look at our diverter valve, they have a harness and wires to them, which is unusual in my experience, but would explain the car's ability to open them on demand versus most other cars where it's simply a mechanical pressure differential that operates them.







Drive the car hard then bring it back to the dealer and ask them to look at ecu codes,
