The dash failures are usually the lcd screen or the stepper motors for the gauges. The stepper motors are available as Ducati uses the same ones and the lcd screen is not available. So even if you can't match the part number, provided the lcd is the same you should be able to swap it easily. I'm no technisian and I managed to strip my dash and replace the lcd. They're plug and play.
If you can find a source for the lcd screen, you would be a demi god for Breva owners. From memory even Carmo can no longer source them.
If I've erred in any of my comments, those more knowledgeable than I will soon chime in.
