B5 A4 AWM - Intermittent P0012

Hey,

I'm getting an intermittent p0012 code. My scanner is calling it "'A' camshaft position timing over-retarded bank 1"

My engine was recently rebuilt. I have gone threw the initial 500-mile break. Then changed the oil to 5w-30 conventional. I don't remember having this issue before the oil change but I also don't remember checking much given my CEL is always on because of deletes.

The code doesn't seem to be thrown with any rhyme or reason. Sometimes it is stored, other times it's pending. It's not thrown every drive and it doesn't show up at consistent at any load or rev range.

I had a low-pressure light once as I was backing into the garage and turned the car off immediately. Checked the oil level which was ok. And then left the car off for 3 days. When I came back the light was gone and has not resurfaced.

Not really sure where to start on this one. When I search some posts are saying chain tensioner, and others saying low oil pressure. But nothing seems consistent
