Just putting this out there for posterity. Had my 20k service done last Thursday at a local dealer and the a CEL later that day. Cleared it and came back the next day. P04DB. Researched and figured either wrong oil or too much, or a hose got disconnected. Nope.. they forgot to reinstall the air filter! Good thing I had an easy weekend or that could have been a mess! That other one was a nox sensor and it never showed back up. Probably related.
