So the end result was that my local dealer here in Portland worked with Ducati to take care and fix this free of charge to me. Rickmeister, reading your description of the fault, mine acted exactly the same. But it had finally left the intermittent fuctioning phase and was constantly showing the tank was empty, at least for about a month before I brought it into service. Then, of course on the day I brought it in, the sensor just started working perfectly, showing the proper gas tank level, and they looked at me like I was high. Well, not really, as this seems to be a common problem on our bikes.
