I find that the HDS has so many "alarms" that aren't actually alarms, more information notifications that I have disabled most of them, otherwise it's constantly beep/ping/ringing. Also it's quite likely that there could be a software conflict between the HDS & PGN sentence from the engine causing the HDS to mid-interpret the signal. Obviously a preheat alarm is nonsense when switching the engine off, ignore.
