Auto High Beam sensitivity
I've got a 2015 A8L with a couple of weird little problems. My main concern is when the headlights are on auto and I'm on a dark road with no traffic something triggers my high beams to go off, and it takes a while for it to figure out there is no other car there and go back on. I'm not sure if it's a traffic sign or the reflectors in the road (northern ca) or what is triggering the high beams off, but there's got to be a sensitivity adjustment somewhere... Of course, the dealer can not see any problem. The really sad thing is my wife's Honda accord works flawlessly on the same roads, it really ticks me off...
The other issue is passenger seat gives my wife a little hug once in a while. Again this is intermittent and the dealer cannot find anything. Someone here had a TSB number for this, but it was for a 2013, and didn't apply to the 2015.
Thanks for any help.

Hmmm. I'm in NorCal too (SF Peninsula), with a 2015 S8 Mine works really well, both suburban and mountains/highway/rural (I80). Variously:
Make sure you know the nuances of auto light function. See blurb below for example about how it automatically turn off as speed drops. Can't tell from your post though if something like that is your scenario. From living on the outside of a curve on my very residential street, I support that. Also likewise really ticks me off when someone drives down a residential street with high beams on (often too fast) shining light into bedroom windows like ours, blinding pedestrians, etc. Why underneath the function is better engineered like that, and I have tested it to confirm that speed related function. Basically it means it is locked out on residential streets if speeds are kept legal. And meantime on open road it can switch like 10x as fast as I can react (if I remember to every time). And yes, it might get a little blinded by a very rare scenario with a retroreflective sign coming back right at you if I really think about it--like once (maybe?) over thousands of miles. But variously it should pop right back and often if things are that close to car and brightly reflecting, it goes back to whether using high beams is the best call. Definitely never had it triggered by a road reflector of any type in lots of settings and miles now. Does definitely pick up car lights very well though, both front and back.
Yes, seats will occasionally do something. Both of mine do, especially on start up after sitting a while. Passenger seat does it a little more from what folks say to me when sitting there.
No, not aware of adjustments for either. If possible for headlights, probably VCDS related but have never come across the info or something obvious in going through modules some over time.

I was thinking the same thing on both accounts... but to add to the auto high beam, I wish it would default to be in AUTO mode when I get in the car....
