CDCA Performance Degradation (SOLVED)

Hello everyone!

My problem:
Brand new Amarok with CDCA bi-turbo engine, only 1000km mileage.
Normal driving conditions: short trips, rural roads, highway.
'Recently, the 'boost' has been missing at 1500 rpm (it should be 400 Nm, which was noticeably present!).'
When I give it gas from 1000 rpm, the thrust doesn't kick in until around 2000 rpm, so my subjective assessment is: the turbocharger has failed. Vacuum hoses are okay, and a warp failure due to damage from a rodent seems unlikely.
Sure, I'm going to the friendly .
Despite that, my question is: Are there already any experiences in such a case?
Unfortunately, I'm unable to connect with VAG-COM or VCDS. I can't log into the control units, even though the test shows 'OK.'
The vacuum sensor pulls full vacuum when the engine starts... unfortunately, I can't observe whether or not the variable geometry turbocharger (VTG) changes during load changes. It's no longer possible to apply full throttle with the vehicle stationary, as the engine is limited to 2500 rpm.
I would be grateful for any tips, and of course, I will post the analysis of the friendly here.
Greetings.
Alex.

So... the already has a recall action on the table.
The oil pressure sensor, along with its associated lines, needs to be replaced, and this could be related to the loader. False oil pressure signal => turbocharger does not engage.
Then let's wait and see; next week I have an appointment with the .

Oil pressure sensor replaced along with the lines, and the engine performance is back. Unfortunately, I couldn't get any information about it; there were also no error messages.

Thank you for the feedback!
