Default 325i Valvetronic issue


I have 325i with n52 engine and problem I have is rough idle and low power at low rpm. There are no error codes stored. But problem goes away when I unplug eccentric shaft sensor. So I looked in ISTA/D live data for valvetronic and it says:
eccentric shaft actual angle 23 degrees
eccentric shaft specified angle 29 degrees
Is this normal or should numbers be the same?
I already changed valvetronic motor and vanos soleonid and nothing changes.

Thank you for your help.
