Sounds like a load, but you may have their term wrong.
Get the actual code for independant verification.
Write such terms down and ask for spelling, location, etc...
Ask them for an explanation of what they want to do, even better have them write it down.
If they give you an unreadable estimate or work order, have them do it over.
Have "save part for owner" written on the work order.
If they do not return the part, raise hell.
Don't get ripped off, good luck.
