Thanks for the replies but maybe I didn't explain myself well,
I always use the lights in automatic mode,
when the light goes out (evening night tunnel etc.) the high beam symbol with the letter "A" appears but the low beam lights continue to work, only in the case of absolute darkness, without other vehicles etc.. the high beam lights come on and the blue light symbol appears (blue warning light),
when the high beam turns off the blue light obviously disappears.
Instead, it happened that the automatic light symbol disappeared,
the one with the letter "A" without me touching anything, then it reappeared.
This has happened several times.
I hope I have explained myself.
