My setting for driving left or right keeps flipping back to right, I have to set it to left - am in UK - but it will flip back to right a day or so later.
Matrix shouldn't dip for oncoming vehicles, instead they should selectively clip the beam so everything around the car in front is illuminated, but not the car itself, in effect putting a car sized/shaped hole in the beam for the car in front.

I’m using the term dip to cover what you describe. If I come up behind a car they do as you describe, make a hole around the car by shutting off selected LEDs. If I am driving on an unlit road and using full beams (in auto mode), and enter a street lit area, the lights auto go to dip - or disable a load of LEDs. If I’m driving on unlit road with full beams on, matrix doing it’s steering round corners thing, in auto mode, and a car comes towards me, nothing happens on my lights, they remain full on, no dip or steering around. It’s a pain because I love the auto mode, but I have to manually dip and return to full for oncoming traffic.

When you first switch on the headlights are in dip.
Push the stick away from you and they go to main beam with an 'A' superimposed on the blue headlight symbol.
Push it away again and the blue headlight symbol loses the 'A'.
Does that mean that it is not going to react to on-coming headlights?
If so, and if we inadvertently drive like this no wonder people flash.

IIRC this is what used to happen to SWMBO in the Tiguan quite regularly:

*SWMBO sets "A" mode by pushing the stalk back once as soon as she starts the car. Drive.
*An oncoming forkwit flashes SWMBO because she has brighter headlights than them, and this somehow offends them.
*SWMBO flicks the stalk back to disengage A mode, but what this does in fact is set the full beam on.
*Oncoming forkwit puts their full beam on too, because the already "too bright" headlights are even brighter now.
*SWMBO flicks the stalk back again to dipped beam mode, and believes that the matrix lights aren't working correctly, because if they were why would the forkwit have flashed you ?
*SWMBO then forgets she isn't on matrix mode for the headlights, and again thinks the matrix lights aren't working correctly
*Arrives at destination, cursing long-suffering hubby by text about the matrix lights not working in the car, then rinse/repeat on the journey home

I am expecting similar beratement when SWMBO ever manages to drive the Tour in the dark.

This is why the auto on our car is a pain, nothing causes it to alter from full on beam for approaching traffic, have to intervene manually which sends you round the loop described above.
