Nervoz

Hi guys, I'm having the following issue with my 2016 2.0 TDI 4x4 DSG. Every morning, when the engine is cold and I start it up, I hear this rattle coming from the right side of the engine. It's best heard somewhere near the right wheel, like in the video below. After a few miles, when the engine reaches 60+ degrees, the rattle goes away. I went to the local Skoda dealer and I was told that it's a "normal" sound and I shouldn't worry about it as it could be the vacuum pump. I was wondering if someone else had this problem, or ever heard that noise before and if you know what could be the source. Thank you.
