Oh it's a P2563. That explains why I couldn't find it. 😊 There's a P2536 in your post. Anyway no big deal.
This is a VGT turbo right. Variable geometry. Don't know if you have possibility to do an actuator test and see if the rod that's connected to the vanes isn't stuck. You could also losen it and check it manually.
The rod travels all the way with no bad spots. Also measured the position sensor for several hours with different rpms. I don't think it is the turbo at all any longer. But it's very frustrating if this code is set due to underboost caused by a leak.

Can't find any leaks? Did you check the hoses from turbo to intercooler and from intercooler to intake?
No noise? Black smoke? Do the hoses become hard (build up pressure) when you rev it?
