I’ve not heard of nor could I find any info on the WC90 code. Also, make sure whomever is doing the oil change is using the correct oil and putting in enough quarts. Diesels use more than gas. I realize this is a simplistic answer so no insult intended, I saw your truck is a 22’ so wanted to make sure you knew.

Man you have a warranty. Take it to the dealer. Don't try to fix it. You will have plenty of time for repairs when the warranty runs out. Plus you do not want to risk the dealer canceling your warranty because you or someone messed something up. Not saying you did, just cover your butt. The dealer covers theirs. Just my opinion.

Sounds like you found an incompetent dealer. Go find another one. Make sure the lights on when you take it.

The code is likely stored in memory for the ECM, so they can see it even though it's not "on".
