Hello, hope you are all well, I have a 2014 428i, I have a strange metallic rattling sound coming from under my car and towards the engine bay when I accelerate, it’s more prominent when I drive past parked cars and the sound is less prominent when I am not accelerating, I have no lights on the dash and the car has 85,000 miles. I’ve attached a video, please if you have an idea let me know it’s doing my head in. Thanks guys

I have a similar noise when the engine is "slightly" warmed up. I've finally spent a minute of my precious time to find out it's the turbocharger's heat shield (just as described, it does vibrate and touching it makes it stop making the sound).
