Sorry for cross posting but figured more exposure here.
So have had a stumbling / hesitation after changing gear but no EML and initially I thought i had no error codes but using Forscan instead of torque pro i do have an error code stored. I have cleared it and after a drive it came back funnily enough the car still stumbles at low revs.

===PCM DTC P0024:00-6C===

Code: P0024 - 'B' Camshaft Position Timing - Over-Advanced (Bank 2)

Status (-6C):

- DTC Maturing - Intermittent at Time of Request

- Malfunction Indicator Lamp is Off for this DTC

- Test not complete
Module: Powertrain Control Module
Freeze Frame #1:

Freeze Frame #2:
-EVENT_TIME: 206628233 s (Sat Aug 26 13:58:17 2023) - Event time


did some electrical testing today. Ignition off values as below
Vct solenoids both banks exhaust vct read 8ohms
Vct wiring bank 1 90ohms bank 2 38ohms (this is the bank with the issue).

So we does that mean there's a body harness issue or is there something else i can check before punting car into a garage ?

Did some logging tonight, er I'm guessing that diff angle is supposed to be a lot closer to zero ?

VCTSYS Closed Loop VCT System status (open/closed loop)
VCT_EXH_ACT2 0.13 ° Actual Exhaust B Camshaft Position Bank 2
VCT_EXH_DIF2 46.69 ° Exhaust B Camshaft Desired Minus Actual Bank 2
RPM 1724 1/min Engine Revolutions Per Minute

also

VCTSYS Closed Loop VCT System status (open/closed loop)
VCT_EXH_ACT2 0.31 ° Actual Exhaust B Camshaft Position Bank 2 - green trace
VCT_EXH_DIF2 12.00 ° Exhaust B Camshaft Desired Minus Actual Bank 2 - blue trace
RPM 6084 1/min Engine Revolutions Per Minute - red trace

got a wiggle graph, looks like the cam is dancing on the spot

VCT solenoid is most likely. Plugged up phaser screen would be #2 and a failing phaser would be educated guess #3
