00575 - Intake manifold pressure: What could it be?

Hello everyone,
I'm having a problem with my T4 (2.5L R5, 102 hp).
I noticed that it exhibits a loss of power above a certain RPM.
Okay, I connected the VAG-COM and read the following error message.

Control unit part number: 074 906 021 L.
Component and/or version: 2.5L R5 EDC G00SG 1450
Encoding: 00002
Workshop code: WSC 02744.
Sure, here is the translation of the text from German to English:

"1 error found:"
00575 - Intake manifold pressure.
17-10 - Rule difference - Sporadically.
He doesn't emit any smoke, everything seems normal. In the first, second, and third gears, I shift up slowly in the fourth gear, and suddenly, the power just cuts out.
There's no whistling sound from a damaged hose or anything like that.

What could it be?

With best regards,

N75
