It has been a couple of weeks where this strange metallic rattling noise appears. It very seldom appear during idle but almost always appear when I step on the throttle.

Please can anyone give me some idea? I have been to 3 workshops but they couldn’t find the noise because it can only be heard clearly when the car is near a wall where the sound can reflected clearly.

I put my feet touching the metal protector deck near transmission pan but it wasn’t loose.

I had this ‘luck’ moment where the car is just stopping and the sound still appear and I can record it (video attached)



Many thanks!
