2001 BMW E46 M47 320D 136HP EGR motion test

I just put this cleaned up original EGR back on the car and revved it up a few times to see how the EGR reacts. The car was not totally warned up yet. The car is running pretty well after this test. If you zoom in on the EGR you can see it's motion better.

why did it sound like it had 2step when you rev it up the first time ? My friend has that problem, is it that a smoke is going in and there is power loss

I do not remember exactly but I think that is just me pressing the pedal only part way down and letting off. it reves up normally when I give full gas the last couple times.
