Weird noise on 3.0 40TDI

Did anyone had this strange rattling/clicking sound issue with the engine? This sound is only when i do the cold start until the engine warms to 90 degrees. It goes away after the engine is warm

Also when i did the oil change and the filter changes, it didn't make this sound for a week and then it started ti make this sound again. Not sure what the issue can be at this point.

Engine warms up until i go to my mechanic for him to check on whats going on.
