Maybe my hearing is not that sharp, there is no noticeable knocking noise at 1:58 to me. At 2:16, when the phone is moved close to the dash(?) the tick-tick-tick noise returns. That seems to be at a lower pitch than the tick-tick-tick from my N26, but there can be a difference between N26(I4 turbo) and N55(I6 turbo).

Is there any trusted local indy that can provide a second diagnostics/opinion?
Thanks for your explanation.
You asked me for a time stamp to listen to the vibration noise, not the ticking noise. The ticking noise is there all the time. This ticking is new to me. I didn't have it before, this is why I am making a big deal of it.
The weird thing is that my dealer blaming in to transmission!!
Even if local indy shop provided a second opinion, my dealer still won't take it , simply because they changed the transmission and fuel injectors!
Could it be a hydraulic lifter problem?
