This worked on my A4 and should work on all Q7's as well.

Here is the coding and adaptations that I used to activate Audi Active Lane Assist, I am not making any promises or assuming responsibility, code at your own risk, But it worked perfectly for me. I do get a few faults but I think it is due to me trying to activate Traffic Sign Recognition.

You will get a few bings from your car about Pre Sense Malfunction, these will all go away once you are done. This will activate the self steering, steering wheel vibration, and lane crossing warning. Do all the coding then do adaptations.


ALL Coding:

A5 - Frt Sens. Drv. Assist
HC>Active | Byte 16>Bit 7
STA>Active | Byte 16>Bit 5
EFP>Active | Byte 12>Bit 3

17 - Dash Board (One of these may already be on, make sure both are)
Lane Assistant>Active | Byte 4>Bit 6
Lane Change Assistant>Active | Byte 5>Bit 3

09 - Central Electrics
Heading Control Config>heading_control | Byte 35>Bit 0

44 - Steering Assistance
Heading Control Assistant>Active | Byte 2>Bit 7


ALL ADAPTATIONS:

5F - Information Electronics

Car_Function_Adaptations_Gen2>menu_display_Lane_De parture_Warning = Set Value to “Activated”

Car_Function_Adaptations_Gen2>menu_display_Lane_De parture_Warning_over_threshold_high = Set Value to “Activated”

Car_Function_List_BAP_Gen2>LDW_HCA_0x19> Set Value to “Activated”

Car_Function_List_BAP_Gen2-LDW_HCA_0x19_msg_bus> Set Value to “Terminal 15”

A5 - Frt Sens. Drv. Assist

BAP Personalization = Set Value to “Not Activated”

Personalization of lane dept. warning Cl. 15 on = Set value to “Last Setting”

System mode, lane depart. warn, = Set Value to “Selection via menu”

Switch-on condition, lane depart. warn. = Set value to “On” (I had to toggle this as this is the final step that I believe mimics pressing the button to actually activate it. You know it was successful when the Lane markings show up in the VC)

You can tweak the vibration intensity, warning time, and steering effort in the A5 adaptations.

Thanks for your hark work, will try it later.

Is there settings to change ALA activation speed? By default it works from 60km/h, want to lower it to 30-40km/h

lapi

wow!great work there, and thanks for sharing!

Mitchfin

Not that I have found yet. Congestion assist can do that but I don't know if you need the full ACC setup for that to actually activate.

I have most of functions included in package, ALA, ACC, Traffic Assist, pre-sense plus etc, but was not able to see green ALA lines on speeds lower than 60km/h, unless traffic assist is active. Might need to look through settings once I get my OBDEleven.

nice work man! Wish you had a Q7 to find its hidden gems ie Sports dial in VC. Do you know how to do the drl to dim instead of winking?

Mitchfin

Those will mostly all be the same in the A4. Will let you know when they are found.

Great that this can all be switched on via the software. Would also love to have Traffic sign recognition.
What about Drivers assist and especially automatic parking? Can imagine you need the radar for ACC but for parking?
Will get my OBDeleven today, bit hesitant to start playing with my 2 month old, 1000 mile, Q7 Premium Plus but my hands are iching

Mitchfin

I'm close on traffic recognition. But as far as park pilot, you need a new front and rear bumper and 4 new sensors and ACC will require the radars. But at least we get something.
