You are way out of specs, so an alert is triggered.
Probably variocam wear

Some of us have changed the variocam pads resulting in the camshaft timing numbers not changing more than a degree or 2, and in some cases, not at all.

Next step is to examine the oil and filter for metal.

I finally had time to dig into this. I took off the aos to get a look at the wiring. Everything looked ok and the voltages checked out ok. I went ahead and replaced the cam position sensor just to be safe. I put everything back and it seems to run a little better but still rough at idle. CEL comes on after a few minutes with the same P0343. I checked the cam timing for bank 1 and it looks like it's maybe a tooth off. Suggestions on what I should do from here?
