Traffic jam assist

Yes, my 2017 S3 has ACC, lane assist and S-tronic.

But again, I'm asking about the Traffic Jam Assist feature which is essentially low-speed (under 65 km/h) lane assist with ACC.

European FL cars have this; Australian, US and Canadian cars do not. For those cars, lane assist does not work below 65 km/h.

I'm asking if coding has been discovered to remove this limitation.

Fine, but my A3 is a UK spec A3. I have ACC but no Traffic Jam Assist as far as I know (no Tech Pack) but my ACC works well in a traffic queue. It stops my car behind the car in front and starts moving again when the vehicle in front moves. If it's within a few seconds it does it automatically otherwise I need to touch the throttle pedal or the ACC setting lever. Is Traffic Jam different?

I've managed to increase the time before timeout for lane keep assist, so now rather then no hands on for 12 seconds it's arround 30.

And here's the code to increase the time to infinite:

Yes, it's been discussed extensively in this forum and this thread: Traffic Jam Assist also steers the car at low speeds ie. under 60 km/h.

The speculation is the necessary hardware is all physically present in the North American and Australian cars - it just requires the right software coding to unlock.

How did you manage that?!

That's great, that it's all physically there, but how do we enable it?
 
Unfortunately there hasn't been a huge amount of development carried out on the MQB platform yet by either the enthusiast community or VCDS themselves. I get the impression VCDS, the US organisation, is struggling. Their website is in desperate need of an update, I've noticed they no longer publish notes on the newer models controller label files and I've come across a lot of Adaptations on MQB cars which haven't even been translated from German yet.
 
Oz MY18's are coming with TJA enabled... so the plan here is to do a straight adaptation comparison. if it's not there, then will have to look in parameters.

Is there a spec list for the My18?

Was posted a while back but was the inclusion of rear parking sensors and one other option which are now standard (can't remember it). But someone contacted me saying their Aug/Sept delivery was an MY18 and they will be TJA enabled in Oz.
Are you going to share how you extended the lane assist hands off time?? :)

Doing a maps update in the morning, was planning on plugging in the OBD1 1 and posting details then!

I did a test drive with an A3 e-tron with the assistance pack (ACC + lane assistance + traffic jam assist) a while back. Lane assist intervention setting had to be set to early for traffic jam assist to work (as noted in the manual).

It was pretty nice. It just felt like a natural extension of lane assist. As long as there was a car ahead of me, the car was basically able to drive itself from standstill to highway speeds. In slow traffic on the highway (below 37mph) it simply handled everything, including steering through curves.

Steering was surprisingly accurate even at lower speeds and off the highway. Traffic Jam Assist is an extra on the lane assist that uses not only the lane markings via the camera, but also the path of the car(s) in front of you to determine how to steer.

You didn't add the coding required.

I'm guessing the actual 'coding' isn't too critical - anything around 0.5 l should do it, but I wonder if it's limited to S-Line flat-bottomed wheels only, or can be retro-fitted to round wheels too. :smiley:

How did you change the timeout from 12 to 30 secs? I have been unable to find it on my 2017.
 
audi upgrades
A5 -> change Emergency_Assist from Not coded to Ea_Variant_2.

You will still get a message and tone at 12 seconds, but the car will continue to steer for another 10 seconds, when you'll then get another tone and finally if your hands aren't on the wheel a few seconds after that you'll get a break jolt.

So I have ordered this feature on my S3.

Currently on my R I have lane assistance and ACC and it does almost the same thing (as the guy in the S7 said).

The difference is that I have to steer and either press the accelerator pedal or press the resume button in slow traffic (if the car in front has only been stationary for a couple of seconds the car will resume by itself which give the appearance of it driving itself).

It does make a massive difference - I also have auto hold - so I don't need to touch the break either.

The difference is traffic jam assist steers and will move off by itself. But all of these features need to be on the car for it to work best - Lane assist, ACC, auto hold, auto gearbox - and it combines them altogether.

I was also under the impression that it used the camera to follow the car in front - it does not need the Lane lines once engaged (which makes sense because you can't see the road markings sitting with cars right next to you most of the time).

I've read through this thread with interest as I have all the hardware in place and would love to have the feature enabled if it's possible, but surely the car would have to have the necessary software already pre coded in and disabled or even a separate module to have this working?
So has anyone actually had a rummage through vcds for any clues to the coding required?

Even with traffic jam assist the car will not move off by itself after it has been stationary for more than a couple of seconds. You still have to press the accelerator or pull the ACC stalk towards you.

That's not what the description is for the feature.

That's just what happens with the ACC alone. But no one seems to have this feature to explain first hand!

Just give me until July when I get my car (hopefully).

According to the Owner's Manual Traffic Jam Assist requires ACC to be activated to work so personally I would assume the stopping and restarting would be controlled and have the same functions and the same time interval for stopping. It also says that the TJA should not be used in the following situations: In situations requiring extra care and attention from the driver; In poor weather conditions such as snow or heavy rain; In roadwworks areas and In city traffic. That together with the fact that the speed must below 65km/h I personally cannot think of many situation when I would use TJA as apposed to normal ACC.

I have this future on a MY17 A3 and it works as I described. Functionally it only adds steering / lane assist below 65 km/h to the functionality already provided by the ACC with stop & go. It can't imagine this is different on an S3 and I have not seen anything about this on the list of MY18 changes. :)

Where are you based?
 
I am sorry, I probably should have mentioned that. I am from the Netherlands, would that make a difference compared to the UK in this case?
 
I so wish I could get this working on my car. I have a 2016 and am looking for any way to help bring the 2017 features to the car. I got mine fully loaded and feel sore that so much changed, when the e-tron and wagon 8v were only available in the US for 8 months before the new version came out.

More likely it sounds like Audi in UK and Netherlands offer Traffic Jam Assist for A3/S3 while Audi in North America and Australia do not.

Physically same vehicles, just different software coding to limit features for whatever regional marketing reasons.
 
then it should be something we can enable? I know that the A4 and other vehicles have traffic jam assist.
 
cuke2u said:
But on the A4 the traffic jam assist requires the front radar to track the car in front. If you have pre-sense then you can enable lane assist only as that uses the camera. https://www.audiworld.com/forums/a4...ctive-lane-assist-all-cars-pre-sense-2907906/

And? My MY17 S3 has front radar, it's available in Australia under the technology pack which I optioned up, but no traffic jam assist, though in the UK cars with front radar they have TJA.

What are you asking? I don't know of anyone who has been able to enable traffic jam assist on the a4 or the a3. Have you the drivers assistance pack or acc and is your s3 a manual or the stronic?

Read the previous posts back to the start of the thread and you'll understand what everyone has been talking about.

Yes and I also now understand the options are different in australia. My answer though is still the same, no-one has yet been able to enable traffic assist as the link I sent in my previous post shows. I cannot answer it in any other way as I previously explained...
