Thanks for the follow up. That’s the exact same behavior my car is not exhibiting. And
sorry the dealerships weren’t able to properly diagnose and fix yet. Have you asked them to check the light sensor? My guess is it’s that.

Happens to my car occasionally too. It’s usually a dirty windshield or direct, bright sunlight that causes the issue. I just ignore it and drive on anyway since the headlight doesn’t bother oncoming traffic. Sometimes it goes off after I drive for a bit. Or after I wash my car.

Took car in for service for headlight today. Service consultant actually saw problem in morning (was very bright and sunny with no clouds), but technicians could not duplicate problem after restarting car. They did adjust the headlight settings to “late” (I had it at “medium”), and toggled the headlight lever from high beam back to normal while in Auto mode. Very frustrating techs couldn’t duplicate problem. Foreman did say take video when happens again so they can document towards case of getting new light/rain sensor replaced if this keeps happening.
Looks like I’m going have to wait a little longer and bring it back when it acts out again. — sigh —

On another note, the 2019 A4 loaner they gave me had absolutely no Auto headlight issues. Drove through dark tunnel, and lights turned on within a second and MMI screen went into night mode, and when drive back into sunlight, headlights turned off within 5 seconds and MMI screen went back to day mode near instantly.

2019 Audi A6 Manual pg 50. “Automatic Headlights: You can adjust the following settings for the Automatic Headlights menu: Headlight Activation Time - You can adjust if the Headlights switch on Early, Medium, or Late according to the sensitivity of the light sensor.”



And yes, I do realize it’s an A6 manual but the settings are the same for all the new Audi’s Automatic Headlights settings.

I referenced the A6 manual because that is what I have. An A6. There were no other forum for the A6-C8s that I found that has the same Auto-Headlight issues. But I heard the light/rain sensor used for the Automatic Headlights is the same across the newer A4, A6, A7, and A8s. Please tell me if there is another thread for A6 that has same issue. I looked everywhere.

Regarding the the old manual. Mine was published in 2019 and the Audi shop foreman also confirmed the settings adjust the light sensitivity of the regular low beam Headlights. And he recommended keeping it at “Late” for my low beam headlights to turn on only after it gets dark later in day. Nothing to do with High Beam Assistant function.

Not saying your settings in the A4 functions same as mine, but have you tried these settings in your car and see if it makes a difference with your Regular Headlights activation time?
