They must enjoy working with you. I am dead serious. I can be a PITA here, but with my SA it is much different. It makes it easier.
Anyway, you SHOULD get a work order and code pulled if you can..at least to get it on the record. Even bringing it in and waiting for them to read and clear it, if all they say is "see if it comes back".
Although, back to the first point, pushing for this before T-day is a bit much.
Thanks for documenting
Keep it as simple as possible...but no simpler.
