Sorry John, it would prove very difficult to diagnose the issue without inspecting the car, although someone might just have had a similar experience. 
Can we take it the noise is/isn’t there when the car is stationary and the engine is revved? 
I fear you will need to get this car to a garage since even if the offending part can be detected, it doesn’t seem as if you could replace it yourself. 
Kind regards,

Gareth. 

Tried to make a video, dont know how good can hear it.... 

Sorry John, all I hear is the usual diesel clatter. It oftens happens that owners post a recording of a noise that is very apparent to them because they become attuned to it as a result of hearing it every day, but we rarely hear anything strange from a short recording.
