Yes, i can switch between ON (blue) or auto when I push the left stalk. I can enable this or disable this in MMI too as I said in previous post.That sounds like Auto Lights to me - which is lights switch on and off when it gets dark. To confirm if you have auto-high-beam then make sure your lights are switched to "Auto" and push back on the light stalk.
If your high beams come on and you get the Blue high beam light then they're not enabled, if you get a white one with "AUTO" written under it then you've got it, your high beams will switch on and off as needed. Some people on here think they're amazing, some said they blind people or don't come on. I've yet to actually test it properly.
It was 50-50 in my previous car as I sometime got flashed from oncoming cars but will give this a go and try. Lightings should be Audi forte anyway?
