Dynamic Light Assist

[kamold]

Ok, yeah, looks like we can only get HBA to work without Kamold's parameters, and even then, we might not have the right headlights.

Kamold, I'll try and get under my bonnet tomorrow and note down the part codes of the physical headlight. It may help you work out which ones are high and which ones are not.

Maybe even just a close up photo of the headlamps from the front (with the lights off) and I will try and get one to compare.

[Wynnston]

Ok, well I stand corrected.

I played around a little more and got it working with DLA (as far as settings are concerned). Took the car for a drive and it activated over 60 in a dimly lit area. The activation was more of a roll up of the light rather than the instant shutter with HBA.

I'm going to eat some dinner then go for a longer drive where I can do 100 km/h and it's dark (I live in the middle of the city).

My headlights didn't do the funky DLA startup, just the normal AFS wink process. I noticed that there is an adaptation option for "Presentation Mode" which I can't activate because I don't have a security key. This might be the key to getting the fancy startup mode.

Does anyone know what the security key for Module 55 - Headlight Range Control might be?

[Wynnston]

So I can confirm that it's working as DLA. The headlights dance all around the place and cutoff the beam with oncoming traffic. I was a little concerned it wasn't working properly, I had a car with dim tail lights about 100m away and it looked like I was blasting them with high beam, so I'll only use it on open country roads whenever I travel down south.

The good thing is that you still have full control over it, so you simply don't have to turn it on if you don't want to, or you can have manual main beam control with an extra push on the stalk.

I have to note that I don't get the fancy startup sequence. It's still the same level adjust up and down followed by the AFS dance.

Try login 20103 for the A5 camera if you need it.
Did you run basic settings, and then acknowledge basic settings after you changed the coding in A5 and 55 and the adaptations in 09?

I wonder what the differences are between your car and DR074s that mean yours can enable AFS and his is only HBA?

[DR074]

I'm trying to look through my settings now to see if anything stands out. Only thing I can find is below;

Control Unit: 09
Fernlicht_assistent: Erweiterte_Fernlichtsteuerung: AFS, FLA, Fernlicht (GLW,MDF)
Static AFS light: bei Rueckwaertsfahrt: both sides

Static AFS light:

Vorschrift: ECE R119

You need to set bit 6 manually in VCDS - there isn't a description in the label file currently.
Sorry I don't have a B8 so hopefully this desciption will help:

The raw coding is counted from right to left, starting at bit 0:
Coding
0 0 1 0 0 1 0 1
7 6 5 4 3 2 1 0
Bit number

So if your coding is 00100101, you need to change bit 6 to active, making your new coding 01100101

Given your success I am getting a feeling that the parameter set may only change the startup sequence of the headlight range contoller, rather than activating the feature.
We should be able to come to a conclusion with DR074's car hopefully - if he can also enable DLA and still have the old startup sequence (and he is willing to try) we can then change between the AFS with MFD parameter set and the regular AFS set and see if there is any difference other than startup.

What Byte would the above Bit

be in?

Ahhh, I only have OBD11.

The only long coding I have in Control Unit 09 is in the subsystems for WWS and RLHS

Hmmmm.

[DR074]

Would the backup file for some of the control units help?

How do I upload a .txt here?

Were you able to apply all the coding and adaptations per the link you posted?
If so then you need to run basic settings on address 55 headlight range, and then run acknowledge basic settings.
I haven't done this with obd11 so you'll have to check if these two are available. They are 2 seperate routines. Both need to be run to success (a few seconds each only)

I couldn't code Byte 2 Hex 0E, but did the rest.

Dynamic Light Assist came up in the centre console as an option, ticked, ran basic settings and acknowledge basic settings.

Tested, when I flick the left stork forward for high beam, a white icon comes up in AID like the one in on the DLA website, High Beams are not on. Lights are on Main Beam. In testing, lights were normal until no cars were coming toward me, then the light increased a little bit. There is no difference in light when in normal or with 1 flick forward of the stork.

A second flick forward of the left stork puts on the actual High Beam, with the little blue high beam icon. High beams are now on.

A flick back of the high beam stork, puts lights back to normal.

Is the HBA, or DLA?

I think the clearest indication would be coming up behind a car - did you see a darker section in the middle protecting the car in front from being dazzled?
Hopefully Wynnston can give a better description than me as he actually owns a B8 [emoji3]

So, I don't have the startup sequence of the DLA system but can confirm it is working because it manages the beam when oncoming traffic approaches instead of just turning off like HBA. I'd love to work it out to get the DLA presentation working because it looks so much cooler.

There are two sets of instructions on that page. I followed the instructions for => 2017 models, but I did not have 4B so I followed the instructions on coding the 55 module from the < 2017 version, I didn't have Byte 4 bit 6 as a tickbox so I manually modified the code (byte 4 is now 4F Added a 1 to position 2 in the binary (is bit 6), I then also ran basic settings and then the apply basic settings. I had "Light Assist" errors come up in the MFD before that, now no errors.

DR074 probably has his working just like mine and we may have confused eachother because the startup sequence didn't change.

[DR074]

I think you are right Wynnston, I may be confused. The description on the DLA website sounds right, but could be mistaken.

My testing may be skewed, as its daytime, I had to close the garage door. This may not be the best test, as I think the camera picks up the garage door. I will do more testing tonight, coming up behind a car, etc, and see what that does.

It wont work under 58 KPH and I dont think either of us have the fancy startup sequence. Here is a good example in this youtube video of how DLA would behave, the fog does exaggerate it a bit.
