Automatic headlights stopped working

Unless there's been an update to the user manual, the A4 manual does not mention this for regular headlights. The headlight activation time only applies for high-beams. I don't know why you reference the A6 manual because the settings are clearly not the same.
See pg. 54 on the A4 user manual:

OK, so there seems to be a lot of confusion going on in here.
Headlight Assistant is "auto high beam," which is only enabled if you've done it through OBDEleven. This does not control any of the automatic low beams, however, the automatic high beams will only work if your headlight switch is on Auto and you manually enable it by moving your turn signal stalk forward. A new icon will appear in the dash of the high beam icon with AUTO underneath.
Now for why the headlights remain on even though it is sunny and bright outside may be attributed to two things, and is not isolated to just Audi.

- Harsh lighting. While dawn or dusk where the sun is creating harsh lighting (i.e. when the sun is just above the horizon where it will wash out cars, people, etc.) your headlights will remain on as a safety feature.
- Front camera sensor is blocked, dirty, or damaged. Unless your windshield was replaced or Pre-sense was incorrectly calibrated, this is rare.

And, yes, my headlights usually stay on when it's early in the morning and the sun is low in the sky. But it seems that the headlights stay on too long. Especially when the glare outside requires me to wear sunglasses, but I have trouble seeing my MMI screen, which is dim.

I had a similar issue with my auto headlights coming on with the sun out. Not a big deal except it puts the MMI screen in night mode which was annoying. I changed the setting mentioned earlier from "medium" to "late" and the problem has gone away.

Regarding the Auto Headlights keeping the Low Beams on: I understand your rationale about the safety feature at dawn and dusk, but mine also stayed on indefinitely (even during mid day 1-2p where sun is directly overhead and bright). I have kept my Auto Activation Time setting only to “Late” now and it seems to be working better.

Yep. Same thing for me. “Late” seems to be only setting that works properly.
