LED Adaptive Headlights w/ Variable Light Distribution (VLD) - High Beam Assist (HBA)

In response to some questions in another thread, that were off topic, I'm starting this thread to clean things up.

To summarise, I was commenting on how the LCI LED Adaptive headlights were incredibly good, particularly when VLD has be re-coded on (it's disabled in coding by the factory for US cars).

Here is a video to illustrate the point:


The BlackVue Dashcams record in a way that preserves dynamic range, so you need to turn the brightness up on your phone / monitor / TV in order for it to be seen correctly, otherwise shadows will be too dark, and the headlights won't look that bright. Make it full screen as well if you've not already.

Street sign reflections are almost dazzlingly bright with this headlights, I was really really impressed last night.

I've only just uploaded this video as well... apparently, it takes a while for YouTube to process the higher resolutions of the file. It was 1080p60 originally, and that resolution should be available at some point.

EDIT by Artemis - BMW video of the past explaining High Beam Assist:

You can code VLD, and it is possible with pre-LCI cars with adaptive HIDs. You cannot however code No-Glare High Beam, which isn't what I was talking about. I tried to get this working on the LCI and failed also, for the same reasons. I've posted a thread about that as well, but this one is about VLD rather than NGHB.

I think VLD should work well for your car as well, but I'm not sure if it would work AS well as the LED version. The reason I say this is that I believe the LED units are made up with a number of different individual LEDs, and these appear to be able to move or be enabled / disabled separately.

P.S. You might recognise where I ended up, though it's a little south of you.

For the Pre-LCI guys with adaptive xenons wondering if it's possible/safe to do this:

http://f87.bimmerpost.com/forums/sho...0&postcount=19

Highly not recommended. You will only get partial function and it's extremely dangerous to other drivers. US cars lack the necessary hardware to properly shield the light out of the eyes of other drivers.

Edit: VLD is fine. It's GFHB that should not be coded on Pre Lci's.

That's different... VLD is different from NGHB. NGHB is not possible with Pre-LCI adaptive Xenons and Post-LCI adaptive LEDs. VLD however should be possible with both, and without risk of dazzling oncoming drivers.

In fact to quote from your first link "Partial functionality of VLD can be coded in by removing 8S4, however the beam shaping is not possible. Only the swiveling and beam throw are possible."

This removal of 8S4 is what I'm talking about...

Ahh my bad, I didn't realize you were talking about variable light distribution. I just wanted to clarify that GFHB should not be coded on Pre Lci's since akkando asked about Anti Dazzle in the last post.

Haha, funny how the Dashcam picks up the intake roar. It's all stock though I'm afraid, besides ASD coded off.

This is why I never trust the way something sounds when recorded. I don't notice it sound that way on mine when I am hearing with my own ears.

Indeed... I don't think it sounds that different in real life though to be honest, I can definitely hear the turbo spool up.

You didn't recognise the location?

HBA is High Beam Assistant - USA spec high beams that turn off in the presence of headlights or taillights of other cars and automatically turns the high beams on if no other cars are present.

Anti-Glare, Anti-Dazzle - European spec high beams that enable your car to keep the high beams on without blinding other cars.

VLD is Variable Light Distribution - It only works on your low beams to move your headlights and position the beams on the road depending on steering angle and vehicle speed.

Variable Light Distribution has several different modes of operation:

1 - City Light: Shallow and Very Wide Beam Pattern active from 0 - 50kph (30MPH) (Both Headlamps are Panned outwards 12 horizontal from center and 0.7 lowered vertically)

2 - Standard Light: Same Basic Beam Pattern as with 8S4 Enabled and Headlamp Switch Set to Auto. Active from 50 - 110kph (30MPH - 68MPH)

3 - Guiding Fog Light - Shallow and Wider Beam Pattern Enabled with the Front Fog Lamps On and Headlamp Switch in Auto and Speed 0 - 110kph (Both headlamps are panned outwards 8 horizontal from center and lowered 0.7 vertically)

4 - Highway Light - Long Throw Pattern illuminating approx. 25% further than Standard Light. Active from 110 to 250kph (68MPH- 155MHP). (Driver's Side Headlamp is panned 3.5 outwards Horizontal from center and lowered 0.25 vertically, while the passenger side headlamp is raised 0.2 vertical)

Hi Nezil,
I've been following your post regarding your coding with E-sys for VLD and NGHB. I will be taking my delivery of LCI soon in they bay area, and was wondering what would it take to code VLD on my LCI as this is one of feature that I always wanted from Euro and hated the fact that it gets coded off in US.

I'm not engineer/coder like yourself so what would be the simplest way of coding this. I already have bimmercode and hesitant to go about coding with e-sys.

For a second I thought you were up in mount hamilton but it seem you are south SF somewhere.

I'm guessing you need adaptive option to get VLD working? I have a LCI w/out the adaptive LED lights.

VLD with bimmercode:

Front Electronic Module > Expert Mode >

3073 LaMaster1 > LUT_FLC_FORWARDLIGHTING_Y > 9C,9C,9C (Both)

3073 LaMaster1 > C_AFS_ENA > Enable (Both)

Note: You'll see two check marks. If you tap the top one, the bottom one will go away. Make your selection. Back out. Go back in. Both correct selections should have the blue check mark next to them.

LOL Thanks Andrew..As I wrote my previous post and looking in other thread I just saw your post in the Bimmer CODE app thread. Thank you so much!!

I would like to hit that apppreciate button, but it's greyed out for me.

So I need to code VLD on even if I bought the upgraded adaptive headlight on the LCi? Isn't that what I paid for in upgrading the lights?

So then alll you get with the adaptive headlight package in the US is auto high beams? Seems like a waste of money. In Canada it's 1500$ and it gives you both

I think people here just buy them for the cool angel eyes

I have a 2017 and adaptive xenons were standard so they were just a free perk.

You don't get angel eyes in the US without them? There is no such thing as an M2 in Canada without angel eyes
