my journey to activating DLA on a MY17 Tiguan

what does “automatic headlight control (rain)” do?

if there's enough rain to turn on wipers, headlights come on too

Here are the instructions I've sent to other users to get DLA working on a '19 Tiguan Highline. Credit to AS Coding @ www.ascoding.ch as my instructions are based on his/hers but with the required changes for the '19 Highline.

Sorry it's so long but I've documented each step I took in detail. Here we go...

Module 09 - Central Electrics

1. Connect OBD Eleven to your car.
2. Turn the ignition on, not the engine! These changes won't apply if the engine is on. I've tried it.
3. Go to central electrics module 09.
4. Select adaptions from the list.
5. Find "Fernlicht_Assistent" and go into that menu.
6. Change "Erweiterte Fernlichtsteuerung" to AFS FLA Fernlicht (GLW:MDF).
7. Change "Menusteuerung Fernlichtassistent" to present.
8. Change "Menusteuerung Fernlichtassistent Worksteinstellung" to present.
9. Save your adaptions using the green tick.

Module A5 - Front Sensor

1. Got to module A5 - Front Sensor.
2. From the list select "long coding".
3. At the top of the page click the little 0|1 to go into Byte/Bit format.
4. Find byte 19. Change it to hex value 30. You can change the hex values by tapping on the hex value in the app.
5. Find byte 21. Change it to hex value 40.
6. Save your coding using the green tick.

Module 4B - Multifunction Module

1. Go to module 4B.
2. In the list, select long coding.
3. At the top of the page click the little 0|1 to go into Byte/Bit format.
4. Go to byte 9. Change the hex value to 10.
5. Go into byte 10. Tap the checkbox on bit 6 to enable it. Make sure bit 5 is unticked.
6. Go to byte 11. Tap the checkbox on bit 2 to enable it.
7. Use the green tick to save your adaptions.

BEFORE YOU GO ANY FURTHER...

1. Soft reset your head unit by holding the power button until the head unit powers down then powers back on. You can stop holding the power button when you see the VW logo appear.
2. On the head unit go to Menu > Vehicle > Factory Defaults > Lights

Running headlight basic settings

1. Go to module 4B.
2. From the list, select faults.
3. You will see a fault saying "No headlight basic setting" or similar.
4. Down the bottom of your phone screen you'll see a red circle with a trash can. Tap on hold on it. This will try to clear the fault. On mine, the fault didn't clear but this seems to be a mandatory step.
5. Get out of your car and ensure it's on level ground.
6. Go back to the module 4B main menu.
7. In the list of options go to "basic settings"
8. You'll get another list with some settings you can run.
9. Tap "Headlight basic settings".
10. Tap and hold the green tick at the bottom of your screen. You'll notice the headlights pivot out a tiny bit.
11. Go back to the basic settings menu. Select "acknowledge headlight basic settings" (or similar).
12. Tap and hold the green tick at the bottom of your screen. The headlights will pivot back to a "normal" position.
13. Go back to the module 4B main screen and go back into faults.
14. The headlight basic settings fault is still there. This is the moment of truth. Tap and hold the red circle again. Your headlights should dance and the fault should clear.

Go back into the car and run your head unit reset and light factory default again just for good measure. Turn the ignition off, then back on. You should be fault free and enjoying DLA!

I tried this but on Module 09 after step 09 it asked me for the access code before i can save my adaptation. Do anyone know the working code for this step?

Hi,

I replied to your PM.

The security code for module 09 is 31347

Thankyou so much. Just finish coding it. All worked perfect and successful. Now, i just need a dark enough road with oncoming traffic to check the DLA

Thanks to everyone for the awesome instructions and the posts on the forum. I coded it today, and all seemed to go well - just looking for some night driving to see how it works. I have had DLA in my GTI, and i reckon it works really well - so it will be interested to compare.

Hey Phonebooth/All,

so i've done all those steps, and everything went as expected per your write-up, but now there's no headlight symbol with the 'A' in it, and if i turn on my highbeam manually, i get an error popping up saying 'error Light Assist'.

Has anyone else come across this?

[Hillbilly]

You have obviously done something wrong then because it definitely works Did you push the lever past normal away from you

Go over it again slowly and carefully including the bit you do outside the car.

Just a thought Have you got the correct headlights

Go over it again slowly and carefully including the bit you do outside the car.

I didn't go outside to see if the car is on level ground (it is)... but i don't understand why being outside the car makes a difference here?

My only other thought is maybe some of the coding done for HBA doesn't overlap with DLA, therefore something is amiss?

Has anyone else coded DLA whilst HBA was activated?
