might someone please tell me what might be causing a rattling to start up from around the throttle body on my 2014 BMW 3 Series 316D? It doesn't happen while the car is cold, and it only lasts for three or five seconds. Other than that, the car drives and performs well.
I am grateful.

Is it feasible for you to record a video and then share the URL on YouTube?

It doesn't happen first thing in the morning; it doesn't happen until after around five minutes of driving. Here's the link; thank you. The noise appears to be coming from the front, near the throttle body.

Watched the video and could hear the noise, however a professional inspection is required for a proper diagnosis. That is an unusual sound; I have never heard it before.
