EDIT: Just went out and looked at my gas cap. The seal ring has several cracks in it, a couple of them at least 2mm wide.

EVAP systems can remain is the "fail" or "not ready" state for prolonged periods after code resets, battery swaps, etc. without registering a hard code or a MIL. If you do a search on the subject of getting the DME to reset itself before going to emissions inspection, you will find that some people had to drive the car for several or even many driving cycles and miles before everything reset to "ready"; during which time the car registered "fail" on the readiness test, but threw no codes, so do not expect the car to quickly clear itself if it is something as simple as a gas cap.
