2007 F430 spider - possessed TPMS system.

OK, so it's obviously apparent to me that my dealer CANNOT solve this problem.

After sitting over the winter (on the factory charger) the TPMS system now (upon startup) shows the (!) symbol and cycles through each of the 4 pressures as if they are ALL low.

Then it goes back to "normal" the temp displays and if you hit the button, all of the pressures are "fine".

I've said it's the TPMS control unit multiple times, it's like talking to wall between the dealer and FNA (it's under warranty).

Any RKI's have any ideas besides demonic possession and "Call an exorcist"?

I mean the system isn't the Space Shuttle. Four sensors, Four antennae, some wiring, the TPMS control unit, and a connection to the instrument panel.
