Dynamic Light Assist

[dArK5HaD0w]

Keep an eye on the high temperatures using high beams at lower speed. I got some high temperature errors when using DLA in dark city roads. Probably too busy for the beams to high low left right. Then, I turn to use DLA when it’s nice long dark high speed roads. The LEDs has some specific modes too so it illuminates quite well generally for example city, high way and rain modes.

As I mentioned earlier - the Superb has Bi-xenons, not LEDs like VW.
The xenon bulb is always on. It's the rollers n shutters that do the high beam masking trickery.
So no possible heating issues that u describe off.
With VW, it's the matrix LEDs that do the trickery.

So I had some success tonight. I managed to get DLA activated albeit with 3 errors. I had to omit some of the extra coding on page 2 of the instructions, specifically "byte 8 - binary 03". That prevented me from running the basic settings on the headlights.

Check left low beam light - cycling the ignition cleared this
Check right low beam light - cycling the ignition cleared this
AFS (cornering light) error - unable to clear this one. Will need to research more.

Also I can confirm that the LED light "startup dance" is different with DLA activated. You can clearly see it has two square blocks. I saw it after acknowledging the basic settings and clearing the headlight "no basic settings" fault in 4B.

d. You'll need the pro version to access long coding.

Which i have

Ok, tonight we have a complete success. I've managed to get it all activated with no errors!!

2019 Tiguan SWB Highline with Sound & Vision and R-Line packs.

All steps completed with OBD Eleven Pro

My 4B coding below, note I already had HBA activated. That includes Central Electrics 09 Byte 2 bits 0 & 1 enabled. Not sure if that would make a difference or not.

Follow the initial linked instructions until you get to module 4B.
My module 4B value: 000000050900084E07104F050A000000000000000000000000 0000000000

Run basic headlight settings then acknowledge, clear the headlight basic setting fault in 4B - noticed the DLA headlight dance at this point.

After that, I went into the Discover Pro, Menu > Vehicle > Factory Defaults > Lights. Then I soft reset the MIB. Turned the ignition off, turned it back on, started the engine, all working.

Something to note is the cornering lights, despite not showing an error, didn't work until I did the above steps.

I'll get out on the road tonight and give it a whirl.

I can follow most of that except im unsure how to run basic settings and acknowledge them

I changed the adaptation to AFS,FLA Fernlicht(GLW,MDF) and it did the correct dance, down up flick then out and left the dark patch in the middle then full high beam

But then when i pushed the stalk forward I got an HBA error and the A didnt come up in the headlight assist icon.

Also a soft reset is just turn it off and on again without holding it down till it comes back on?????

My lights like range control seem to be in 55

Hi Hillbilly,

My headlight coding was in module 4B but I believe it's the same as 55.

Before you attempt to run basic settings you should try to clear the headlight basic settings fault in module 55. In OBD Eleven when you're in control unit 55, before you go into long coding you'll see a list of available options (history, adaptions, long coding etc). In that list you'll see basic settings. Tap that menu and you'll see another list. Pick "headlight basic settings" tap and hold the green tick then go back into the previous menu. Select "acknowledge basic settings". After this go back into faults and clear the headlight basic settings fault.

Yep - soft reset is holding down the power button on your head unit until it powers back up.

Have got that fixed and now no faults anywhere Just dont know what to do as lots of light options in there

Let us know how you go after you attempt the instructions I PMd you.

Hey, I know this is on a Tig but I managed to get it working on the Passat too. The downside is that we all think it still required further programming to work properly, not just module parameter changes, but actual programming.

I could get it to do all the stuff, except it wouldn't do the DLA style dance at start-up, just the normal one. It was also a bit slow to react to oncoming cars and cars from behind. It did it, but it was slow. I came to the conclusion that it wasn't quite working as it should and reverted it as I didn't want to blind someone in traffic. I understand from previous posts that the Tigs and some newer cars might already have this programming present, if it doesn't then you might want to look into getting it put in place before using it.

Happy to share my findings in detail over a PM, otherwise, I too am in Perth and have VCDS if you want to try some different things.
