I have fitted all the cables according to the Audi circuit diagram, but still I get a message in DIS saying, "high beam assistant system malfunction". I have also coded the cent. electr 09 to have "headlight assistans installed".
I have made some research on the net about this and turns out that I should recode Can gateway no 19 as well.
Has anybody done this that can tell me what and how to change the coding?

Mattias

 

What does headlight assistant do?

could component protection be a reason for it not working?

Headlight assistant (or maybe it is called high beam assistant) is in part of the rear view mirror.
I am just guessing here, but I guess it is kind of a webcam, analysing the road and light conditions and if needed, turns on and off the high beam for you.

All you guys that have the high-beam assistant, could anybody tell me what part number of J519 or control module 19 in VAG-com you have?
I have 8T0 907 468 H, and I am wondering if this is the one to have for High-beam assistant.

Regards,

Mattias

 

Can you override it as you dont necessarily want the high beams on at times.

Unusual mod I must say

JB:thumbsup:

 

Of course, You decide when the system is on, and when it is off.
You start up the system by moving the "high beam" stalk forward. Then when you move it back to center position, the headlight still stays on= high beam assistant is active. Do de-activate the system, you move the stalk towards you, the way you would to to "blink" with the high beam.

I am a little bit unsure how it works as I have not been able to get the system functioning.

But I am a bit surprised that you have not heard of it. It is available for the A5, but also A4 and A6 as well as A8 i think...

I dont see the point of this mod TBH, if it was light retrofit or reverse camera or hill hold I can see the benefits but I cant with this mod, it just seems very confusing to use the main beam function.

Have you activated it in Vag-com?

Does it work in conjunction with the light/rain sensor?

JB

 

Have you actually got the light and rain sensor package?

 

Some info from Elsawin:-

 

Hello forum!
I need your help!
Could anybody here with the headlight assistant find out what version they have on their can gateway.
Mine is 8t0 907 468 h.
Now my question is if this version "h" is one that supports headlight assistant.

Regards and thanks in advance,
Mattias

 

Have you got the light and rain sensors installed in your vehicle?

JB

 

This forum never stops amazing me! I knew I had it, but never knew how to activate it. Stupid on my part I guess, but I am sure I'm not the only one who didn't know how to activate this system!

 

So have narrowed the not functioning high-beam assistant to a problem that I need a new CAN-Gateway (according to Kufatec). Also, the new module would require some adaptation by my local Audi dealer (also according to KUFATEC)

Would be good if anybody could confirm this. (Can it be done with VCDS?)

Now from surfing the web and another excellent forum (only problem is that it is in German), I have found another guy, doing exactly the same thing on his A5. He has posted a photo of it, and he has the CAN-Gateway called "8t0 907 468 AA" (I have the 8t0 907 468 h version).
If I would buy one of these gateways (have found one on eBay called "AB", would it be a straight swap, or would I need to code it, or the dealer would need to recode it or what..?
What could happen? Could I end up with a car that wont start?

Regards,

Mattias

 

Brilliant mod. Id be very interested in this if you can work it out.
Where I drive, Im constantly switching full / dipped beams. It can become quite tiresome.
Keep us posted.

Ive an outdated version of etka but

8T0 907 468 H is listed for options :-
7Y0 = Without lane change assistant
8N1 = Windshield wiper intermittent control
8N6 = Windshield wiper intermittent control with light/rain sensor.


8N7 appears to relate to highbeam assist in many audi brochures.

Parts:
8T0 907 468J,
8T0 907 468N,
8T0 907 468L,
8T0 907 468Q

refer to 8N7 so maybe one of those would be the right one

Surely someone with up to date etka can shed some light on the part no. required.

Looking at instructions above by JonnieB, Id be pretty sure you need a new indicator stalk as the instructions continually refer to pushing the stalk forward even when in the forward position. It would appear that the stalk for the assistant would have a spring function when pushing forward past the full beam position. Mine doesnt have that.

 

I have talked to my dealer, (the nice, cheap one) and they where very helpful. Although he was a little bit unsure, I said that I needed the "J" version (has been replaced with an updated version "N", so anyone of these will do).

About the new stalk, I am not so sure I would need it. If you use VAG-COM and code it for headlight assistant, the difference is that tha stalk when moving back from the front position, does not turn of the high beam. you need to "blink" with it (move it to the back position as if you would like to blink with it) to turn it of.
I would imagine that when you have it working, you have the stalk in the middle position after having activated it, and then the system will handle the high beam by it self?

And I can also confirm that 8N7 is the code for the high-beam assistance, was told by the dealer.

Mattias

 

I have this on my Q5; although never had the need to use it. You dont need a new stalk as there is no specific version for HBA. I have the 'Q' version gateway fitted; but i do have lane change and lane depature acc ADS etc installed too.

Its down to coding with vagcom

 

So bluetone, you are pretty confident that it will work once new can gateway is fitted?

I currently have auto lights & wipers and also the auto dimming rear view mirror. Is this the mirror that incorporates the front facing sensor for the high beam assist or will I need to replace it?
How helpful are the dealers in coding a control unit that is not specified for that chassis number?

 

I dont know about all dealers, but the one I go to, do what I ask them to do.
They know I know the car well, and understand that I need them to do things that I can not do on my own. And it is a way for them to get money.

Many if not all jobs at the Audi dealer (as I understand it) have "routine numbers". This number is basically, a number so that the dealer can look up what needs to be done to do something. Although I dont know the actual number, I do know that coding a control unit has a routine number, hence Audi has provided the dealers with instruction on how to do it. Therefore, I think all dealers should be able to do it...?

Mattias

 

can anyone tell us how to wired this?

 

I will have a look on Elsawin and post a diagram up

rgds
JB

 

By the way the headlight switch is also directly related to HBA. 8K0 941 531 AL and some other ones too have the switch that has 8N7 PR code.
You need to check what your switch part no is and its PR codes

 

I have the switch called 8K0 941 531 AA.
I have managed to figure out that the "AA" version has been replaced with the "AL" version. However, I am having trouble finding if my version ("AA") is compatible with high-beam assistant.
Could anybody help me with figuring out if it is?

Regards,

Mattias

 

i got from elsa diagram but i dont now so well to 'read it' can any body can help me.?

my car (audi a5 spk 2010) has light and wipers sensor and auto dimming just the interior mirror.

i have a inside mirror with auto dimming and headlight assistant , and humidify sensor.

the plug from my original mirror has 6pins and the new one has 8 pins.

i have a little problem how to wire this pins.

can some one who now how to read well elsa can advice me?

 

My system only lists 8k0941531F & G with G being listed with PR 8N7. My system is out of date though

 

Ok, feel that it is time to do an update.

For installing the high-beam assistant (a bit sloppy i have called it headlight assistant in some of my posts), you need the following.

rearview mirror (8K0 857 511, there is also a letter after this. From what I know there are 8K0 857 511A, 8K0 857 511C and 8K0 857 511E.
The letter stands for what software the high beam assistant has.
Apparently some people have been complaining about the assistsant not working very well, hence I would recommend the "C" and "E" versions.

Also you would need to replace your can gateway. Now finding the right one is a bit tricky, as the can gateway coverns some other functions in your car as well. Also, there is a difference between cars that have MOST (fibre optical cables, recognized by having a 2G or 3G nav system in your car), or CAN based (regognized by not having navigation in your car).

I have cruise control, rain and light sensors an a coupé, hence I have a can gateway called 8T0 907 468 H (has later been replaced by "M") in my car. This one I need to replace with 8T0 907 468 J or N version (J was the earlier version and "N" the later one). To find which one is good for your car, look in ELSA or ETKA (if you have it) and look for the PR-code called 8N7 (which is "audi code" for high-beam assist)


When you replace the can gateway (and eventually start your car, the car will go into component protection mode. This is a feature Audi has implemented to prevent theft and selling of stolen parts. Basically it means that you wont have any interior lighting, the AC wont work (at least i think so), and the instrument lights will go dim. In the DIS you will have "SAFE" written.
The car is drivable, but you should take it to the dealer to remove the component protection (adaptation/SVM coding to your car). You can switch the gateway back to the original one and get a fully functional car again, but the error codes will still remain in the memory the ECU.


Also, you will need VCDS coding of the car/enabling the high-beam assistant.


You would also need to connect some cables, but I am sure somebody here on the forum can help with the elcetrical schematics.


Any questions? give me a yell (PM), or post in this thread.

Hi everybody,

I'm french and come from Reunion Island (in indian ocean). I have an A4 B8.
I'm intersted about this thread cause i've retrofited high beam assist on my car.
I've got the good mirror and done all connections.
I've changed my CAN Gateway to "N" one, and my Audi dealer unlocked component protection.
But there's still a bug, i got mess "dysfunction", and on vcds i can enter the 20-high beam assist and code it but when i do a scan it says that it could not be reached.

Is anybody have an idea. And is anybody know what is the signification of all the bytes when coding high beam assist ?

Thanks

 

I havent really gotten that far, as the idiot that I bought the gateway from on eBay sent me the wrong one on purpose (because it was a "better one"..?!?)
Anyway, I think you need to change the code in two places, not just on.
Central electric.
According to he information I have (although unconfirmed, you do it on your own risk), you need to change it in three places.
1. The actual gateway
2. Central elektric (09)
3. Steering wheel elektric

Although I dont know what in the codes needs to be changed. Maybe somebody with high beam assistant can help?

 

Really looking forward to this... Great job!

Do you think it would also work on the starndard Bi-xenon with auto leveling only (Up and down, no AFS) ?

 

It shouldnt be a problem, the only thing is now we need to find out how the coding is supposed be of the module, steering wheel and central electronics..

Mattias

 

i made this retrofit and i have same error... a messege on instument cluster "hight been dysfunction"

any solution?

 

What can-gateway do you have ?
What is the number of your mirror?
Are you sure that you have connected the wires correctly?

Mattias

 

Am I the only one that thinks this is an enormous amount of effort for very little benefit? From what I've read, you even need to push the stalk forward to operate it, so you're not even saving the calories of doing that!

That said, we each want our cars to be perfect, so from that point of view I can see it's defensible.

 

Its not that you need it. I have done a lot of mods on my car that are, to be honest completely unnecessary. The read light LED retrofit was a complete waste of money. The folding mirrors as well. But that is not why you do it, now is it? I do it because it is a challenge to figure out how it is done, and it is fun. And it makes my car look better.


Now back to the issue at hand I have managed to install the Can-Gateway now (or my dealer eventually did). Now I have the symbol in the DIS with highbeam assistant on, but I think that I need something more changed in the programming. turning on the highbeam assistant in the central electrics module (with VCDS) does not seem to be enough? Anybody can help with that?

Mattias

 

I know its out of topic, but i was wondering what was the code you needed to change for the OEM LED reading light retrofit.

I did mine on the audi a6 2012, and when i open the door the lights don't go on. And the switch (door open) doesn't work. Any tips ?


Thank you

 

Everything works like a charm..

Turns out I have not yet been out of the city yet...until this morning.
Hence, the assistant has not turned on the high beam until this morning.
The High-beam assistant is working just fine...
So I can confirm that the only programming needed for the high-beam assistant to work is to tick the option of high-beam assistant in 09 central electrics.
