X5 M Turbo broken?

[mirob]

Here is a video I took earlier today. It's on a 2011 X5 M with 57K miles.

It's me moving the camera/phone from one intake bank to the other, with the housing removed. The left/passenger bank is making the sound, which I can only describe as a wobble. There is no sound coming from the other intake bank, besides the background noise.

Not sure if it's the turbo going out or maybe some sort of exhaust leak making the sound but I'm preparing for the worst.

If it's the turbo, may replace both with Pure Turbos.

Anyone hear anything like this before? Deal with this issue? Any help or suggestions would be appreciated.

Thanks.
