As you can hear in the video, there is a slight rattle coming from the front of my M54, it sounds like it comes from the oil pump area, but I might be wrong.. It is there all the time, but it gets a little bit louder as the engine heats up, especially if you drive it hard.
Could this be as simple as a bad idler pulley, or is it more serious?

Any tips appreciated :)

+1, remove the belts and repeat the test - don't do it with a hot engine and don't let it idle for more than a minute, without the belts on the waterpump wont be turning, at least that way you rule out anything terminal.
