......The large turbocharger has a wastegate, while the smaller one is connected via a valve in the manifold.
Both vacuum cups are working, or, alternatively, the rods are easy to move.

Checked with actuator diagnostics?

Okay, I'm ready. Please provide the German text you want me to translate.
In the default setting, I have checked the turbocharger (a), as well as the biturbocharger (b) and the EGR, and everything is I.O.

Only when checking the boost pressure regulation (c) does it throw the aforementioned error.

I have inserted (a), (b), and (c) into the quote. We need to figure out exactly what is being targeted at (a), (b), and (c).
Is this all in the default settings? Are there any other settings available for the boost pressure control? What possibilities are there in actuator diagnostics?
