Problem is limp mode because of issue attached in log.

When I ran output test by VCDS both wastegate actuator on bigger turbo and electronic regulator on smaller turbo works fine, tryed operating wastegate actuator with vacuum pump and it holds well without any leak. But I am still getting this error and car is completely undriveable with this error.

I believe the problem is around the " Bypass valve f high press turboch turbine inlet" but no solid idea where to look at when looking from front of the car.

Can anybody help please?
