Traffic Jam Assist

[SolarRS3]

After using vcds to code the lane assist with early vs late intervention i switched my sight on getting traffic jam assist enabled.

From the info I was able to find, a vag can cable is needed and vcds wont work, but I was not able to find what/how to code the module to enable the feature.

Anybody here has done it or has more information on how to do this modification?

[peshs4]

I had to talk to a guy from Australia that remote controlled my laptop while connected to vag can...he then did it for me works great and you gotta PayPal him once it works...

Do you have any information regarding enabling TJA? I haven't been able to find any substantial information as to whether someone has been able to code it in etc.

[SolarRS3]

the only other info I found is from a VW forum and another Audi forum. Where, indeed, guys from Australia has found the way to code it into their a3 Q5s. I am just unsure if they can do it on can/us cars and I don't have the name of the person to contact. The only thing you would need to buy is a Vag Can Pro cable and then pay for the service (seems it was 150$ on the forum from the guy in Sydney)

[thejerseydon]

what about Audi pre sense city while we are ACC usage?

Thanks for sharing all! I think TJA would be awesome. Not that I don't mind spending $150 to have someone help program it, but I also hope that someone else can figure it out and share.

[SolarRS3]

I sent en email to the man in question, and I let him know about all the guys that could potentially be interested over in the states/canada for his service.

[BaltimoreCaesar]

so what does this actually do? makes adaptive cruise resume from stop after 5 seconds and follows lane lines at slower speeds?

[SolarRS3]

mix adaptive cruise control, lane assist, side assist as well. It uses the car in front, side and movement of those car to follow them and turn in curves. it work at low speed and seems like a more intelligent lane assist (than when used alone at highway speed for exemple.)

[peshs4]

Main thing is it turns for you...and allows you to set lane assist to “early” this keeps the car dead center of the lane when cruising....

Any way you can share this guys info i would like to contact him to code my car.

[steven5210]

I'd be interested as well! Where do you guys get your vag can pro cables from? I saw some for cheap on aliexpress but I don't know if it's good.

Ross tech VCDS. The cheap ones use pirated software which is just wrong and on top of that is most likely outdated and might now work on recent cars

im sure getting cable and software is easy part. just need to find someone that can code it.

The contact I found is [email protected] he can do this remotely but you need vag can pro (not a copy)!

thanks i will shoot him an email. did you ever end up getting this done?

[steven5210]

Thanks for the info. I emailed him will be getting it done once I get me the cable.

you code anything else? how to you enable traffic jam assist or does function with regular Adaptive cruise control is enabled?

I coded a bunch of other stuff my self needed him to do the traffic jam assistant....he had to flash the camera first then some other things..works perfectly

No, never got around to get the cable! And I left the city for a while, not as much need ofr it now.

Below is from Woolly on AW - is he who has been helping people? On that forum, looked like they were using ODBeleven exclusively to do this?

A little treat I found in my research – how to activate the ALA guidelines in the HUD:

HUD Module 82
long coding
Lane Departure Warning -> set to available.

HUD Module 82
Adaptations
Personalized settings MMI
Lane assistant -> set to yes

Traffic Jam Assist Coding
I made so many attempts at this so I am not going to guarantee the following is in the right sequence (but I don’t think the sequence matters that much to be honest as if it did mine would not be working). Usual disclaimers need to be noted that this worked for me and not saying it will work for you or if it is legal where you live etc etc – try at your own risk!

My car: MY18, Built 2017, SQ5 Australian delivery. Has all add on’s (DAP etc) but it seems for these cars in Australia they do not include TJA, ALA or the traffic sign recognition (note for the traffic sign one I am waiting on a Kufatec dongle to enable that one as it does need parameterization of the camera). Have previously activated ALA following MitchFin’s instructions (and it works great) from this forum so note that ALA was activated before I did TJA as below.

After each and every change (ie each long coding and adaptation make sure you long press the green tick to accept each change as you go).

Control unit: 13 Adaptive Cruise Control
Long Coding:
Assistent_for_traffic_hold_up -> activated
Traffic_jam_assistant_in_car_menu -> activated
Traffic_jam_dependent_linear_tracking -> activated
Driveaway by triggerleaver -> activated
Auto driveaway after short stop -> activated
Auto driveaway by pretrigger -> activated
Curve_assistent -> activated
Dense_traffic -> activated
Emergency_assist ->installed
Emergency_steer_assist -> activated

Note – some of these were already activated – I assume they are part of the stop & go function of the ACC.

Adaptations:
Nil

Control Unit A5: Front Sensors Driver Assistance System (Enter Security Code: 20103 before coding)
Long Coding
STA -> coded

Adaptations

Nil

Control Unit 44: Steering

Long Coding

Heading control assistant -> active
Traffic jam guidance assist -> active

Adaptations

Nil

Control unit 5F: Information control unit (Enter Security Code: 20103 before coding)

Long Coding

Nil

Adaptations

Fahrzeug funktionsliste bap2 generation erweiterung:

Front_traffic_assist_0x41 -> activated
Front_traffic_assist_0x41_msg_bus -> terminal 15

Vehicle configuration:

VZA pro: On

Once all the above have been done, and you have accepted each change successfully as you have made them, reset the MMI. Once re-started I then hit the car on/off button to turn off. Get out of the car and lock it. Wait 5 minutes then get back in and start the car and go for a test drive (in multi-lane traffic, moving slow with good line markings)

Hope it works for you all.

[SolarRS3]

Never heard of these OBD/VCDS change to enable it, interesting to try when the snow clears the roads.

[stanglife]

I reached out to the guy you guys referenced in this thread. He sounds like he knows what he’s doing - states that the article I referenced is Q5 and that the platform doesn’t share much with the RS3 and that the assist hardware is also different. I’ve ordered a VCP and when it arrives, he will remote in and show me what to do. Cool car guy. Will keep you guys posted. If it works out, I’ll offer to rent the tool out for others to offset my cost a bit. :)

[SolarRS3]

Awesome, keep us posted stang!

How'd it go? I've been trying to find someone to rent this tool from too and the other guy I reached out to on the VW forums hasn't got back to me yet. If it worked out well for you I'd definitely like to rent it from you so I can get it done too!

[stanglife]

Waiting on vcp tool - it’s stuck in Poland :)

I was thinking the same thing in regards to renting someone's. I'd be down to do the same.

[peshs4]

I am willing to rent my cable....not sure how payment would work/ deposit.....if you check my post towed the top I have posted the e-mail of the guy who did mine...he is in Australia I think and he does the work then has you test it then you send him a paypal.....I was skeptical but he does not ask for payment till it is done....please let me know if someone wants to borrow my cable I am in south jersey so figure you would have to pay for shipping to you and probably a deposit I would PayPal back to you once you got the work done.....if you are serious my suggestion would be to talk the guy and set up time to get it done....then let me know I can send the cable....

I should have just rented yours :) I'm interested in seeing how to do it, too. The way he described it was that he would show me what to do - so maybe I could then help others or just document it. He actually said that he would do it for free but donations were appreciated, which I think would be appropriate.

Looking forward to it. I emailed them today and they said that I would have to wait and something about a USPS mail problem...I guess at some point, the packages move to USPS and that's what I'm waiting for.

So if you have acc the car basically drives itself? I drive the e-tron and was really impressed how well it held lanes on the highway.

[stanglife]

So if you have acc the car basically drives itself? I drive the e-tron and was really impressed how well it held lanes on the highway.

ACC is stop/go radar assist cruise control and that works from the factory.
ALA is auto lane assist and it also works from the factory but it has 2 things that could be improved on. 1 - it doesn't hold center...allows the car to get pretty close the line before it corrects, resulting in a ping pong effect between the lines 2-3 times before it requires steering input (it tells you and then turns ALA off!) and 2 - it only works above 40mph.

We are talking about TJA - Traffic Jam Assist which apparently 1 - adds the "early" option to your ALA which keeps the car in the middle of the lane and 2 - will hold the car in the center of the lane all the way to 0 MPH. It will also go longer without steering input...but will ask for it eventually. This is not auto-driving but in a well-defined lane (lines on both sides) can stop/go and keep the car in the center of the lane all the way to 0...so it kinda drives itself but it's not going to change lanes and make decisions for you.

[Potshot]

Thanks for the clarification. I know "driving irself" may not be the most accurate description, but I meant more like drives itself in a lane.

Do we know how long it let's you not give input. After about 45 seconds the e tron beeps at you and then actually pumps your seatbelt! It has sensors in the wheel. I assume the rs3 requires input in steering since it doesnt have steering wheel sensors.

How does the rs3 notify you? I wouldn't want this mod if it's going to keep at me every 30 seconds.

I’m not sure on the lane assist but I understand that the current 3 second timeout at 0mph (when you would then need to touch the gas to resume ACC is increased - someone said 15 seconds but we will see!

[WheeRS3]

Hi everyone, I was able to use the VCP to flash TJA thanks to peshs4 lending me his cable. Thanks to him, he got me in touch with the guy in AUS who helped him out.

Julian taught me how to flash the new parameter set to the camera to help the community. So happy to help!

Some pointers, you need to have Early configured for lane keep assist for the TJA to work. If you don't have it and set to Early, TJA will not work even if you flash it. It had slipped my mind and I was bummed that it wasn't working on one of the cars we flashed. After an exciting but discouraging ride back with BaltimoreCeasar, just as we were about to park I suddenly remembered! So don't make my mistake!

It allows lane keep assist to work below 38 MPH. So for example, you set it on the highway and if it slows down due to traffic, it'll still stay centered in the lane automatically. When traffic starts up again, you hit the gas or pull back on the stalk to get it moving again. It'll automatically switch from Traffic Jam mode to standard Adaptive Cruise Control.

As for time duration, it appears that it is the same amount of time as using normal ACC.

Hope this helps!

[SolarRS3]

Wow thanks for the update! How much did it end up costing you to have it enable in the end

[peshs4]

So I was contacted by two other members that wanted to rent my cable...I ended up sending it out and asking for shipping cost and a $100 dollar deposit that I would send back once the next user got the cable and ensured it worked....this worked and we have got a bunch of us Rs3’s activated with TJA let us know if you are interested in getting this done and we can make the same arrangment....

So I made a donation to Julian since I kinda figured it out but appreciated his time answering my questions and using his experience. Also made a donation to Pesh for the cable. So my cost is probably not what everyone's cost will be.

That being said, I'd be willing to help the community by providing the instructions on how to use the application when you have the cable. It's nothing secret but figuring out which parameter file to download and how to navigate the application.

We ended up flashing the new parameter to four RS3s this weekend and they all appear to be working.

Entire process shouldn't take more than 10 minutes. The application install and all the associated downloads is what takes the most time.
