Help needed! 16396 fault code

[Andy91]

I checked for codes this afternoon and this came up
i have a 51 a3 aum


16396 - Bank 1 : Camshaft A (Intake): Advance Setpoint not Reached (Over-Retarded)
P0012 - 35 - 10 - - - Intermittent

I've heard it can be oil pressure related? But I have no idea, I took the sump off for a clean and changed the oil last week if this could be anything to do with it ? And I also have an erratic idle!
Any help and advice would be a great help thanks

Does it keep returning after you've cleared it? I've seen this a few times on my car but it normall goes away when cleared.

Yeah I cleared it and I will look in a couple of days to see if it comes back, but it's the first time I've seen this come up so I'll keep an eye on it
