I thought about the same but no, we can't reset the service indicator on the dash via the Guzzi App / MIA ... unfortunately. The two are completely disconnected. The Guzzi App checks the bike's mileage independently and based on that prompts you to answer whether the service was done or not. It seems to remember the mileage you confirmed last time though and asks you 10,000km later. On the flipside, the dash service indicator automatically pops up every 10,000km on the clock so at 10,000km then 20,000km, etc. It doesn't count 10,000km from the last time it was reset unfortunately. And also there's no way of resetting it without PADS, as it's the dash computer displaying the service indicator and not the main ECU.
