Adaptive headlight issue

Hello, I have a 2015 335i xdrive m sport with about 44k miles on the dash. I have an issue with the adaptive headlights, or a question about them. I have the dealer sheet and it shows I have the adaptive headlight package, yet when Iím driving I donít notice the headlight adjusting in any way when turning the wheel or anything. Is there something I have to do for these to work? I have no errors on the I drive system for any lights or anything. I even looked up my vin on mdecoder.com and it shows I have package s524 adaptive headlights. Any help please?

In my 2016, I believe they only move in the auto position on the light control module, but I also have to press the button on the bottom half of the left turn stalk.

Bottom half of the turn signal only activates auto high beams, not necessary for the adaptive functions to work, so the lights will move with or without doing this.

The Mulroney for my 2016 has an extra line: adaptive headlights coded off. This was due to US regs. Check your sheet.

Incorrect...US spec cars have the anti glare auto high beams coded off (5AP) as well as variable light distribution (8S4). Both can be enabled. Other than that the adaptive headlights are functional in both xenon and LED.

With the anti glare and variable light distribution coded off they just function as automatic high beams. I took it to a pro to code them on, but he was unsuccessful. When the dealer updated the carís software last year the anti-glare feature started to work.

US cars have on or off high beam assist, with coding as you mention they can be adaptive. Mine are coded as remain so even after dealer updates. My point was that normal adaptive functions remain when not using the high beams.

This thread is mixing and matching 3 different features:

-Euro "anti dazzle"
-Auto high beams
-Adoptive front headlights (swivel)

My car has adoptive headlights, which, as noted above, will only swivel if the headlight position is in AUTO.

I do not have auto highbeams, which is activated by a button on the turn signal stalk, if you have them.

The "anti dazzle" feature isn't available in the US, but some have said can be coded if your car has the right headlight configuration.

Thank you, I was about to post something similar to clarify the situation.

To elaborate on the "anti dazzle" functionality (aka non-glare highbeams (NGHB)), in the US market only pre-LCI US adaptive LED headlights have the necessary hardware to support this feature after the proper coding has been done. No other headlights in the US market support NGHB at the hardware level.

US market cars have two option codes added to the vehicle order (VO) that disable certain functionality: 5AP disables NGHB, and 8S4 disables variable light distribution (VLD). I won't go into the coding details as this is covered at length elsewhere.

Regarding VLD, this functionality enhances adaptive headlights by shaping the light projected based on environmental and speed conditions, IE at low speeds the beam is spread out and shallow, and at higher speeds it narrows and raises up to shine further away. VLD can be enabled on any adaptive headlights, US or otherwise.

High-beam assistant (HBA) is required in order to enable NGHB (along with KAFAS2 camera) but otherwise has nothing to do with adaptive/swiveling headlights. With NGHB disabled all it does is automatically turn on/off the highbeams based on the presence of cars in front of you. If you have enabled NGHB, the HBA button is what turns NGHB on/off.

Edited to state that in the US only pre-LCI adaptive LED headlights support NGHB at the hardware level, no other headlights in the US support this.

Also, if you have Adaptive Headlights and they are in the ON position, when you start your car they do a quick movement check. You can also, while parked with the Adaptives on, just look at where the lights are aimed and move the wheel to the right and left, the beam should move.

The reason you cannot code in NGBH properly is those lights have additional hardware shutters built in, we don’t have those.

My adaptive LED NGHB don't use shutters and work very well, including tunneling. Not getting flashed (anymore)

high beam asist problem

hello guys. i have o problem with my kafas 2 camera. after the windshield replacement the high-beam assist didn't run as before, the sign recognition ran normaly and when i went to a shop to see what was the deal he found out that it needs to calibrate. i went out for a ride to calibrate the camera and i got a error message about the camera based system and to visit the shop. i did this 2 more times with the same result. now as i'm writing this i realised that the calibrations were done at night. have any of you has the same problem?
