long time lurker, first time poster.

I recently took the plunge and picked up a 2013 R56s N18 with 30k miles, well maintained by an older owner for a solid price. Regular frequent oil changes. Aside from having to replace an ignition coil and swapping tires/ needing alignment, a concerning sound has started occurring which I need the forums help with.

It started one morning and hasn’t gone away. It is a high pitched metallic kind of grinding sound, which is directly linked to acceleration and deceleration. It does not occur in neutral when coasting. It gets more prominent as I accelerate . It’s very prominent with the windows up and sounds like it’s coming from the front right of the car. I still have full boost.

I’m worried that this is the turbo prop grinding against the wall. To be clear, I know there is a turbo whine that comes with the R56s which it used to have and this is not it.

I apologize for the quality in video, for some reason the iPhone isn’t picking up the pitch very well, but it can still be heard.

It’s a manual

So it makes the same sound regardless of standing still reving, moving and reving in neutral or in gear. It is directly toe and step linked to the acceleration and doesn’t really vary from day to day or the warmer/ colder it is outside.
