Hi Guys
I have a F10 520D M Sport, and its started to make some noise which is annoying me

It happens only when accelerating around 10mph and when slowing down, sounds like its coming from under the car or one of the driver side wheels

To describe the sound its like something metal banging around something, i've cancelled out any trasmission problems as ive put it on neutral when slowing down and it still makes the noise, its like somethings loose somewhere or a stone banging around somewhere

Had it up a ramp in local garage yesterday gave it wacks on the bottom cant seem to find any loose heatshield or anything broken

Gave the brake disc shields a wiggle and no movements,

Where could the sound be coming from? Sounds like metal to metal contact as dissapears as gradually increasing above 10mph-15mph and appears when slowing down again

Any help would be appreciated
