Well, I was wrong - nothing to do with the service menu. It was just the first thing I tried in the new app version with the car running. Turns out, it boops every 10 seconds or so, no pattern with the connection status (which I always have showing anyway, not sure what it does while hidden). On the driving screen, I discovered the problem: tire pressure! The top two numbers are correct, but the bottom two report very strangely - I believe it showed 34 PSI and 1 PSI (the top two were as expected, about 44). If they were that low, I'd have a dash indicator, and definitely wouldn't be driving.
Curiously, this happened both before and after my short 16mph test drive down my street and back, so the tires were activated to get a reading. I haven't seen this condition before on previous drives - the tire pressures were either stale or not shown at all ("--", I think).
It was definitely an alarm for tire pressure, though - and since my tablet connects audio through Bluetooth to the stereo, it played the alert sound over the speakers
