Has anyone had a repair. My dealer says it is "just a calibration" issue.

 

Well, Has nothing to do with calibration, your dealer is making up a story, I hate Dealerspeak.

My problem was on the extreme side, and now has been resolved.

Suggest you have your dealer contact/email tech line and / or touch base with their Field Tech Mgr, Mr Perkins (he knows!).

Problem has to do with Inner Fill Pipe and Anti Spill Back Valve.
One opperation that was performed was "Recall A604 Scope 2"

Keep advised as to the solution for your problem!
