my journey to activating DLA on a MY17 Tiguan

[TIG162R]

Thanks guys, so just to confirm, your icon looks like this on the dash yeah?

Hi, from my obs on the Tiguan the setting for Byte 10 Bit 3 stops the right hand side light from reverting to normal beam at speeds above 100km/h.

With that setting checked on between 80-100 I get DLA with both sides working on adaptive, steering high beam. At speeds above 100 the right hand side reverts to normal beam only, but the left side maintains adaptive, steering high beam.

With that setting checked off I get both sides with adaptive, steering high beam at all speeds >80km/h

I cannot think of any other changes I have made that might affect this. I took some time to verify this specific change. Did you do a light reset and head unit reset?

Legend! Finally got DLA working properly!

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!

Thanks so much for the detailed instructions Phonebooth!
I had attempted it with instructions found on the OBD forum, but it never quite got there.
Followed yours to the T, and it all went through, cleared any errors, and worked perfectly, so much appreciated.

Is there a way to have the default mode (when the DLA isn't active) set to highway lights? (I believe that is the best for forward vision is it not?) As for the majority of my commute there is too much traffic for the DLA to really do it's thing. It is very cool when it does kick in, but when it's not engaged, I still find the distance lit up by the lights to be very short, and would appreciate a more focused beam in front of the car.

(Even since doing this mod I have noticed an improvement in the height of my lights, previously they would only come to the bottom of the rear bumper of most cars/utes, whereas now it comes closer to the number plate, which is what I believe it should do)

If you go into long coding and change it to English and go down there is a setting for Highway_ lights and in mine its enabled.

If you go further down there is another setting for highway_lights ( notice difference) and it is disabled Maybe try enabling that

A quick question: With DLA, do both low & high beams remain ON at all times? or the high beams only come on when you push the stack and see the high beam icon in white colour with letter "A" in it?

They just do what it normally does except they split around other vehicles etc. Have never gone out in front to see what happens. Get someone to stand in front and watch.

Both low and high beams are ON at all times in my car. Both the beams vary according to traffic, external lighting and maps inputs.

My impression was that the high beam will be OFF but turns ON when you push the stalk.

Only if you have the stalk pushed forwards though

Mine has both low and high beams ON even when the stalk is not pushed, though the high beams are positioned the same as low beams. Is this normal?

Pushing the stalk enables the DLA & AFS to operate as expected.

HI Everyone,

A couple of questions: ON Module A5, byte 19, for bit 0-3, I've currently set to 00 (FLA_additional_high_beam,No additional high beam), My car has LED low & high beam. Should I be selecting: 03 FLA_additional_high_beam, LED?




Another Question:

ON Module A5, byte 13, for bit 1-2, has anyone set it to Steering wheel vibration active? Does it work?


Also, should bit 0 be ticked for TSR?

Cheers!
