Default T5 rattle on startup

2008 Volvo C30 T5 with 145k miles.
Loud noise on cold startup that sounds like a rattly dry bearing that morphs in to sounding like diesel knock.
Fades out after a few seconds.
Appears to be coming from the area of the exhaust camshaft a few centimetres inboard of the drive pulley.
Is not a loose exhaust stud (I've been down this route having found a YouTube video of what appeared to be the same problem)

This leads me to suspect VVT - in which case, solenoid or something else?
Agree?
