Audi A6 RPM Problem

[Gogo]

Hi. I have a big problem and i need your help. I have Audo A6 2.7 140kw Multitronic 2010 car and the problem is next:
Sometimes the RPMs (while i am driving and keeping the same speed, not accelerating) goes to 1320rpms (tested with VCDS) and normaly it should be around 1000rpms. When this happens i need to keep driving the car for about half hour and it will just go down to 1000rpms (again while i am driving). This happens once in a while. If i dont drive the car when this happens until it goes away it will hapen again sooner than if i drive it until it goes awey. I posted a video on youtube (link at the end) also because no one knows what the problem is. I need your help. Thank you.

I forgot to say that i have no error codes in my car. I have tested it with VCDS software.
