Adaptive LED headlight issue

[meds1976]

Hi all,

Noticed tonight the inner part isn't lit. Any thoughts?

Checked Real OEM for parts but couldn't really figure out what exactly I need.

This is normal, if the car has Anti Dazzle and the LED matrix enabled.

Mine used to light up the entire part until I had those two options coded, now they light up and turn off depending on conditions as needed. A good check to see if you've had those options coded in would be to part in front of a wall, turn the headlights on, and then engage reverse. If the driver side sweeps from side to side, you've got one or the other option enabled.

Another check would be to activate the High beam assistant (button on the end of the turn signal stalk). If you notice that the high beams enable and sweep from side to side depending on oncoming traffic, especially above 40 MPH, you're good.

Thanks SMIK90. Will check that tomorrow as per your recommendation.

My only comment is. This is in the driver side. The passenger side is all lit up. Still to do with anti-dazzle?

So with the lights on manual setting, it's all fine. It only goes off when lights are on Automatic setting.

So assuming it is a anti-dazzle feature etc.

City light european coding, it will come on once you get to a certain speed threshold.

Makes sense. But why only on the driver's side? Assuming to not impact oncoming cars?

Here is what variable light distribution looks like
