Will try to take logs tomorrow (getting late here).
@Lantanafrs2 - how was it resolved? I actually had a P0018 code about 18 months ago, replaced an OCV, and ultimately had to replace the ECM to get rid of the code. My guess is that the engine did not like 5w30 oil (syn) during the colder half of the year (I think it first happened in Nov/Dec, so maybe around 30-45 degrees?). Ever since it's been fine.
