Exactly - well said, gentlemen.
If you don't have a problem, then don't go in asking for a reflash (update).
If you got a reflash but the dealership service technician failed to place the required "Authorized Modification" sticker under the hood (which will now look like a slightly oversized oil change label - you know, the see-thru kind) with the updated program code written on it, then you will need to take the vehicle back in and have them read it with the WDS (Ford's Worldwide Diagnostic System). As John mentioned, that takes all of 5 minutes to do.
What a great bunch of helpful vehicle owners - this thread is an excellent example of F-150 Online and it's members at it's best, all helping each other out with accurate info - kudos, fellas!
