I can confirm that long coding for adaptive lane control works in the Tiguan eHybrid 2021 EU/Nordic and show the difference with pictures.
Worth mentioning is that regardless of whether ACC is active or not, the Lane control system is active at speeds above 60km/h and only then.
First Info about A5 module I have.
(Double click on the images to view the full image.)
Approach:
1. Pop the hood (Edit: Also activate the parking brake)
2. Switch on the ignition. (But not the engine.)
3. Connect OBD11.
4. Enter module [A5 Driver Assistance].
5. Enter [Security access] enter code [20103].
6. Go into Long coding, search [Point_of_intervention].
7. Change to [early_setting_over_menu].
8. Go back to Home screen and disconnect from OBD11.
9. Switch off the ignition.
10. Close the door and hood, and lock the car.
11. Have a cup of coffee.
12. Now the function is active the next time you use the car.
Here are some pictures that explain the differences.
An interesting thing is that I had the Adaptive line guidance menu bar before I made the change. But no matter what I put it on, nothing happened. But now it activates or deactivates Early or Late intervention. Early intervention causes the car to steer towards the center of the lane instead of steering like a ping pong ball between the lane markings.
Note that with Adaptive lane control (Early) active, you get wide white lane markings. Without (Late) it will be narrow lines for lane markings. See the difference in the two images below. Also note that the green symbol is not displayed when Adaptive lane control is active, except when the system is searching for the lane markings.
The two pictures below show the difference with and without Adaptive lane control when you do not have the Assistance view active.
Note that in the upper two pictures the ACC is not Active and in the two lower ones it is. So regard less of ACC lane control is active.
EDIT: Add more changes to get better function and Traffic Jam Assist.
I was not entirely satisfied with how the adaptiv line assistant work with only change the [Point_of_intervention]. So I did some more research and come a cross som information in this forum thread: www.vwvortex.com/threads/enabling-lane-assist.9459882/post-115382132
Names of some Adaptionen Channels is not the same as in the forum thread but by going thru the settings I found the corresponding channels om my 2021 Tiguan eHybrid.
(I include the corresponding information from forum thread in parantes and step 1 to 8 is corresponding to above coding.)
Extende approach:
1. Pop the hood (Edit: Also activate the parking brake)
2. Switch on the ignition. (But not the engine.)
3. Connect OBD11.
4. Enter module [A5 Driver Assistance].
5. Enter [Security access] enter code [20103].
6. Go into Long coding,
7. Search [Point_of_intervention]. (Byte 08 > Bit 5-7 Set to "80 Point_of_intervention,early_setting_over_menu")
8. Change to [early_setting_over_menu].
9. Search [Configuration_for_lane_departure_warning_Kl15]. (Byte 09 > Bit 0-1 Set "03 Configuration_for_lane_departure_warning_Kl15,Last_setting")
10. Change to [last_setting]. This is optional but it makes the car remember last setting, with out this change will Lane assist always be activated when starting the car.
11. Search [HC_advanced_takeover_request]. (Byte 09 > Bit 4-5 Set to "10 HC_advanced_takeover_request,coded")
12. Change to [Coded]. This was coded already in my car.
13. Search [HC]. (Byte 09 > Bit 7 Activate ("HC,0=not_coded / 1=coded")
14. Change to [Coded]. This was coded already in my car.
15. Search [Hc_messages]. (Byte 17 > Bit 0 Activate ("Hc_messages,0=not_coded / 1=coded"))
14. Change to [Coded]. This was coded already in my car.
16. Search [HC_Warn_Intensity]. (Byte 17 > Bit 1-3 Set to "02 HC_Warn_Intensity,Setting_over_Menu")
17. Change to [Setting_over_Menu].
18. Search [Hc_variante]. (Byte 17 > Bit 5-7 to "20 Hc_variante.Variante_1" or "00 Hc_variante.Variante_ 0")
19. Change to [Variante 1 OR Variante 0]. My was Variante 0 so I change it to Variante 1. (I think this is what gave me line assist below 60km/h with ACC active. I will try the other variants to see what's happening.)
19. Exit Long coding.
20. Enter adaptations.
21. Search [Switch-on state Lane Keeping Assistant]. (Module A5 > access authorization: 20103 > Adaption "Switch-on state Lane Keeping Assistant" set value to "on (setting via menu)")
