Citroen C5 drops the RPM

[Tokesz]

My car: Citroen C5 2002 RHZ (DW10ATED), manual

Dear forumers!
Someone help me

The problem:

When i would like to speed up the car drops the RPM. There wasn't any shift in the video.

To drop that quickly I think it must be an electrical fault in the rev counter circuit, does it sound as though the revs are dropping?

The video doesn't play on my screen.

OK on mine Peter.

yes, it sound as though the revs are dropping. I feel the car stopping at acceleration as if the turbo pressure ceased.
I chacked the turbo wastegate and it's ok. It holds the vacuum and moves smoothly. The vacuum system is faultless.
I thought there are any problem whit the clutch, it may slip but it was replaced 20,000km before that.

I looked at the video again and noticed that the revs went up first and then down, sounds more like the clutch slipping to me.
