Travel Assist

For what exactly do I need a capacitive steering wheel? Because right now if I turn on lane assist and I don't hold the steering wheel for some time it starts alerting me to grab the steering wheel... Is it working like that because I'm not "counter-steering" and don't have a capacitive, or because I have a capacitive?

Is capacitive pre-requirement for Emergency Assist?

Huh, many questions... Sorry for this many questions...

By the way how do I know if I have a capacitive steering wheel, is there one needed in order to make this features work ?

It does not allow me to activate the unit 13-complete coding-trip assistant-active. And coded with the hood open, did you have to do anything to code that 13 unit? I don't know if it would have to do with something that doesn't have the signal recognition option? It's the only thing that comes to mind. It is the only step that does not allow me to activate it. Condemnation!! xdd

Hi, 

if it helps I will report the changes I made as a result of various internet studies, in parentheses I report what was the default for my Audi A3 eTSFI.

The following codes activate for me: ADAPTIVE LANE ASSIST + TRAFFIC JAM ASSIST  + EMERGENCY ASSIST
I had by default ACC and LANE ASSIST
I don't have, because I don't have the radar: REAR TRAFFIC ALLERT, SIDE ASSIST/BLIND SPOT


13 - Adaptive cruise control

Long coding

Curve_assistent ---> Activated (default: Deactivated)
Assistent_for_end_of_traffic_jam_1.0  ---> Activated (default: Activated)

Driveaway_by_triggerleaver  ---> Activated (default: Activated)

Automatic_driveaway_after_short_stop Deactivatet ---> Activated (default: Activated)

Automatic_driveaway_by_pretrigger Deactivatet ---> Activated (default: Activated)

Travel_assist ---> Activated (default: Deactivated)


NOTE: The majority of these helps in the traffic jam configuration.



5F - Multimedia

Adaptation

Vehicle function list BAP

- front_traffic_assist_0x41 Not activated ---> activated

- front_traffic_assist_0x41_msg_bus Not activated ---> Terminal 15

Vehicle menu operation

- menu_display_lane_assistant Not activated ---> activated

- menu_display_lane_assistant_over_threshold_high Not activated ---> activated



A5 - Driver Assistance

Long Coding

Point of Intervention ---> early setting over menu (default: late)
HC variante Variante_0 ---> Variante 2 (default: Variante_0)

Emergency Assist ---> EA Variant 4 (default: Not_coded)
KLR ---> Coded (default: Not_coded)




09 - Central Electrics

Adaptation

Flashing function

- Fahrerassistenz_Blinkenfunktionen      Warnblinke_zulaessig ---> Wechselblinken_Warnblinken_Bremsblinken (Turn on external lights in case of emergency)

- Warnblinken_durch_Fahrerassistenz      not active ---> active (Flashes the high beams in case of emergency)

- Hupen_durch_Fahrerassistenz      not active ---> active (Turn on the horn in case of emergency)

- Travel Assist      not active ---> active

- Innenlicht_durch_Fahrerassistenz      not active ---> active (Turn on internal light in case of emergency)




pACC (which I really would like to have) is not, for what I understood, available for my car, I know that is possible to activate on Audi Q3 for example.
TRAVEL ASSIST, which also I would like to have, need the presence of side assist. If I understood correctly helps also in automatically overtaking cars. 

The only problem I registered is that since I don't have capacitive touch steering wheel, sometimes when I activate the lane assist, I have the message to put my hand on the wheel. even if they are already there.

Hello colleagues, I am going to try to contribute my knowledge as best as possible since I am from Spain and the translator can sometimes fail.

I have been informing myself in the skoda and vw post as well, to be able to shed some light on this.

mbackonja, I think you are missing some steps and others are a little confused, the errors that occur when you put reverse, such as SOS failure, are due to the lack of steps in the Emergency Assist coding, in this option to activate the following:

A5: long coding, emergency assist - EA Variant 4, and it does not belong to the Travel Assist coding, therefore, you get a series of errors related to SOS assistance, below I describe the exact coding for your SOS assistant to work as expected without any errors in the picture.

1- module 09 - adaptation - Fahrerassistenz Blinkenfunktione (or also called flashing function) - Fahrerassistenz Blinkenfunktionen -Wechselblinken Warnblinken Bremsblinken.

2- Warnblinken durch Fahrerasassistenz -activated. Hupen durch Fahrerasassistenz -activated.

3- Travel Assist -activated. (This last step that I put in does not appear in my car, but it activates it for people who see it).

4- Innenlicht durch_Fahrerasassistenz-activated.

Next we leave module 09 to go to module:

1- 03 and in adaptation, we select delay management-emergency assistant-activate. (Changing the value to 03 starts a series of errors in the virtual. Turn the ignition off and on again, the errors disappear by themselves.)

And finally we go to the module

2- A5-long coding- emergency assist - EA Variant 4.

This last step together with the other previous ones will ensure that you have the SOS emergency assistance option completely activated, and not like before, which was incorrectly configured, not within travel assistance, which does not belong there.

IMPORTANT!! BE VERY CAREFUL WITH TRYING THIS SOS ASSISTANCE CODING AS THE VEHICLE WILL ATTEMPT TO MAKE THE EMERGENCY CALL WITH AUDI AND MAY NOT BE ABLE TO CUT OFF THAT EMERGENCY CALL). The performance of this system will be as follows: it will suddenly make a couple of strong shocks, it will sound the horn, turn on the emergency lights and finally it will make the call to Audi and I think to the SOS authorities as well.

With that said, now on to travel assistance coding. First of all: BE CAREFUL with the car that turns ONLY BUT DOES NOT DECREASE THE SPEED in curves or at intersections.

We begin.

1- A5- complete coding- point of intervention - early setting over menu. (activates adaptive lane guidance with the possibility of setting the intensity in the menu). Early intervention causes the car to veer toward the center of the lane instead of spinning like a ping pong ball between the lane markings.

2- Hc variant - variant 2.

And as I see it was missing.

3- HC Warn Intensity- Setting_over_menu. (activates the trip assistance menu).

4- Lane Assist Off Text- activated. (displays an icon on the dashboard to show whether Travel Assist is activated or not).

And then we go to the module

13- complete coding and activate travel assist. (This step doesn't let me activate it, I don't know why).

With these steps we will have activated travel assist correctly.

As my colleague says, I have also read that to eliminate all the error messages that constantly appear when the steering wheel touch detection is defective, the KLR option in the A5 module - full encoding should be deactivated. And I have also read that it must be deactivated in module 13 - long coding - capacitive steering wheel.

I have also found this other video in case it is of any use.


This is what I can contribute and up to this point I know.

Hello mate! Correct, this post is for travel assist, I only talked about the so-called emergency assist so that it was clear that parameters were coded within the travel assistant that belonged to emergency assistance.

I think it's impossible to stop what happens to you when you activate Lane Center - Active Lane Guidance and its yellow warning every 15 seconds. The car is not autonomous, it is not a Tesla, it is semi-autonomous and I think we can't do anything about that. Up to this point, semi-automatic driving is the most we can do. It is my opinion.

This is the end mate

Edit:
Okay, some new info...

On the Audi A3 configurator, when I just select just a basic Cruise Control I get a steering wheel with a "circle" airbag, but when I select Lane Centering I get a "trapezoidal" airbag, just like audi8y2021 said (images attached)...

So, trapezoidal steering wheels possibly have capacitive sensors and they don't need to steer left-right in order to detect your presence...

1. Any idea to trick the system that I have a capacitive steering wheel (for example coding that it's installed, enabling KLR etc)?
2. Did anyone on this forum retrofit the capacitive steering wheel?

Without Lane Guidance:


With Lane Guidance:



Edit 2:
In the last video - the guy said he doesn't have Travel Assist because he has this S-Line steering wheel with a flat bottom (and with a circle airbag - confirmed my previous message)... But he somehow has the Lane Guidance? Maybe he is using HC Variante 1?

No updates?
I'm thinking of trying HC Variante 1 over a weekend

Hi.I have same problem as mbackonja. I created a new account to reply this topic. I made adaptive lane guidence with obdeleven but when i turn on adaptive lane guidence my steering wheel turns left and right every 10 seconds.

If anyone finds a solution please let us know.

hi, I have a 2023 A3 8y with factory lane assist and Acc, I would like to activate travel assist (lane assist below 60 km/h) and emergency break assist. What encoding should I use?

but does the emergency break assist stop the car?

Hi everyone,

I have a problem when I follow the steps in this topic : I have departure lane assist on my A3 and I managed to activate the lane guidance (the car will stay in the center of the road). I tried these options but it doesn't work. I even lost my departure lane assist from 0 km/h now, just enable from 65 km/h..

A5: long coding, point of intervention - early setting over menu
A5: long coding, Hc variante - variante 2

Does anyone knows what settings are missing ??

PS: ath the same time, I can't change anything in dashboard menu (17) "function unavailable".. strange no ? 
Thanks.

Hi mbackonja , first thanks for all your input. I just wanted to ask if you by any chance got the steering wheel moving every few seconds fixed? I was thinking to perform these adaptations on my car but if that is the way the system behaves, it’s no point in doing it. Could it be related to the emergency assist settings? Thank you!

UPDATE: I performed the following actions on my 2023 A3 Sportback with 3801 software:
Control Unit A5 Driver Assistance
long coding: point of intervention -> (old - late) (new - early setting over menu)
long coding: Hc variante -> (old - variante 0) (new - variante 2)
long coding: HC Warn Intensity - Was already set to: Setting_over_menu

Control Unit 13 Adaptive Cruise Control
long coding: Travel Assist -> (old - Deactivated) (new - Activated) - I saw that multiple persons mentioned that this coding was not accpted by their car but on mine, it got accepted.

I did not perform any of the emergency assist or traffic jam assist codings that are present here as i don’t really need those functions, and i also don’t want to mess things up. All i wanted is fro the car to keep the center of the lane during long motorway trips. 

Unfortunately i was not able to test yet the functionality of the system on a motorway, but i did some tests on some single lane country roads and everything seems to be working fine. The green triangles appear when i activate lane guidance and car keeps the center of the road. I haven’t noticed the random left right steering wheel movement, i even tried to keep the hands off the steering wheel until the “take over steering” warning appeared and not even then nothing similar happened. 

Just to mention that my car has the non capacitive flat bottomed steering wheel, this is also the reason why i did not activate Travel Assist from factory as i would have been forced to choose the round steering wheel with the big trapezoidal airbag. 

I made some enquiries and was not able to find anything about the activation of pACC on the A3 8Y. I managed to find that it is possible to do it on the Q3 but from what i saw even if Q3 also uses MIB3, it is built on another platform, A3 is based on MQB evo and Q3 is based on MQB-A2 so maybe the hardware behind pACC is different and this is why for the Q3 this can be done but not on the A3 8Y. I did not find a single mention from someone claiming that they activated pACC on A3 8Y. 

Thank you to everybody that contributed to this topic. 

Tested this on A3 8Y Sportback S-Line 2024 with no adaptive cruise control and factory Lane Assist.

Travel Assist:

A5: complete coding
- point of intervention - early setting over menu
- HC variant - variant 2
- HC Warn Intensity - Setting_over_menu
- Lane Assist Off Text- activated

13: complete coding
-travel assist – activated


All changes working expect module 13 travel assist activation (error when trying to activate). For this case, try 20103 security access code on module 13. Then you can activate.


AFTER ACTIVATION: no Travel Assist working on my car (because I have only Cruise Control)

Then I bought 1 month of ACC because my A3 8Y only have CC and yes, TA started working perfectly (only with ACC enabled – appears the green triangles) ... but the same as some of people here, If I drive without hands then the car say to me to put my hands every X seconds. I don't know If mine is capacitive steering wheel or not (I think no because the steering wheel needs to be moved, not touched, on this warning) , I have the basic buttons and round one. This was with HC variant 2.

So, I tried HC variant 1 and then I started driving and WITHOUT ACC, from 65km/h I have Lane Assist + Active Lane Assist without green triangles. Same indication to take the control after X seconds.

I will post more impressions.
