Kent's description above is the best I have found. With respect to the service indicator light, that is NOT an OBDII reset item. You need the Maserati computer to reset that. I'd just live with it as it only flashes on at beginning of start-up.WOW! I just got my 2005 Quattroporte and while it's got good service records, but has just clicked over a year since last service (only 2,000 Miles). I was thinking of doing the service myself (I've built several cars so have experience, but never an exotic). Has anyone done this and taken pics? or is there a manual floating around the web at all?
Also can I reset the service warning OBDII scanner?
