I too am having this issue with the low fuel indicator always flashing (in ACC). It isn't a hotlap-specific thing, it happens in all modes including while playing multiplayer races. It only started happening after installing version 1.9. I was using 1.7 previously, and haven't had an issue with that version.
I'll sometimes notice it'll eventually go away several laps into a race, but more often than not it's always blinking at me. I'm can't think if there's some trigger to when it stops flashing (pit stop maybe?). IMO this is the best dashboard available for ACC, I still use it despite this problem, but would be great to figure it out. Let me know if there's anything I can provide to help troubleshoot.
At the very beginning of a session, I notice it has not yet registered any fuel values (and the low fuel indicator is flashing). Maybe the low fuel condition isn't being unset once the fuel values do become available?
