Traffic jam assist

hi guys,

I've ordered a car with lane assist and side scan, and have adaptive cruise control. The traffic jam assist was an extra £500 so I didn't spec it, but as far as I can tell it just requires the ACC radar and the lane assist camera to drive you at under 37mph. Does anyone know if the traffic jam assist can be coded in?

I know technically I have a "manual" version of it now, but when I come to a stop I have to put my foot on the brake and then start it again by activating ACC. It will then stop for me when the car above does, and the lane assist will keep me in lane (if applicable, there being a enough white lines and what not)

Any thoughts on this?

They must have changed ACC in the FL then as my PFL deals with traffic just fine. So long as you remember to set it before you drop below 19mph. I'm assuming jam assist lets you turn it on when stopped then?

Basically traffic jam assist means you don't need to put your foot on the brake when you stop and it will turn corners for you. ANd start automatically again for you once the car in front moves. It's fully autonomous driving under 37mph

You still have to have your hands on the wheel though right? I thought that ACC didn't require you to brake when you stopped anyway, and lane assist already does the corners so as far as I can tell it's just that they have enabled lane assist below 37mph and called it something else.

I think you're right. So I guess the question is, has anyone figured out how to enable lane assist at below 40mph?

According the the current Price Guide there are two types of Automatic Cruise Control. One includes automatic distance control with Stop and Go function which brings the car to a stop and can automatically restart (according to certain conditions) and this is for cars with the s-tronic gearbox. The other version is just called Automatic Cruise Control and is for cars with Manual Gearbox and does not mention bringing the car to a stop and automatically starting again.

I have the former on my current A3 which has a s-tronic gearbox.

Do you mean Adaptive cruise control, rather than Automatic?

This has been the case since the original 8V launch though - those 2 options haven't changed.

Those are the 2 options on the list. I want to know if the traffic jam assist is available through coding. Lane assist works up past 40mph and ACC works past 20mph. Traffic jam assist uses the above up to 37mph. I'd really like to have traffic jam assist, it sounds awesome.

Yes, sorry I do mean Adaptive cruise control. Quite what extra Traffic Jam Assist provides over my current Adaptive Cruise Control I don't know. Perhaps it's just something needed by a manual gearbox as the Price List indicates. When I come to a queue a traffic I set ACC and it keeps my car a set distance from the car in front. When it stops my car also stops. If it starts moving with a short time then mine moves forward with it without me doing anything. If we are stopped for slightly longer then I have to pull up on the control lever or press the throttle pedal to move forward. It will take my car up to the speed I have set and stop me when the car in front stops at the distance I have set. My A3 has been connected to the computers at Audi AG via my dealers computers to give me an extra closer stopping distance than is normally available as standard. It needs the s-tronic gearbox for all this to work automatically and move the car from stand still without touching any of the pedals.

I assume this is what I will get on my new facelift A3 as well.

So if you have to stop for say 1 minute, what does your car do? I have to put my foot on the brake and then press the button to resume it afterwards

I've never actually timed the stop time but I know if it's a short time my car will automatically move forward when the car in front moves. If it's a longer time and the car in front moves and mine does not immediate follow it I have to tap the throttle or pull the setting upwards. I understand their may be a difference if you have a manual gearbox as, unlike an s-tronic, you cannot stop with a gear and clutch engaged as the engine will stall. The Owners Manual describes the various differences on page 120 for an 8V.

As far as I know, Traffic Jam Assist is not available on manual gearboxes, only S-Tronic.

Had our new s3 for a few weeks. Traffic Jam Assist didn't make it to Australia, reckon I could enable with coding? Optioned up the assistance pack so all the gear is there? it's S-tronic so I don't see why not.

If it is the same system as the A4 then it needs the two radar sensors and the windscreen mounted camera. Lane assist only requires the camera..

Anyone with a Facelift S3 and traffic Jam Assist able to check how many radars they have?

I might have actually been wrong as I think the A3 will need the single radar sensor under the front number plate for traffic jam assist, which is, as pointed out, for the acc. The windscreen camera is used for lane assist though...

I'm in the US, and I would really love to figure out an answer for this. I recently was driving to Las Vegas, with pretty much stop and go traffic. The adaptive cruise control worked extremely well, except for 1 or 2 minor unintended acceleration when switching lanes.

It would've been great had this vehicle had the traffic jam assist. So I wouldn't need to steer the steering wheel at low speeds. I'm guessing if we can some how enable lane assist at lower speeds (less than 35), I would probably be happy with that.

This isn't a Tesla, and does not have Tesla levels of autonomy onboard.

Lane assist is only available on highways (hence the higher speed activation threshold) and uses a camera in front of the centre mirror to detect the edge of the road and the white line lane markings

Actually Audi and Tesla share the same level of autonomy, Audi just chooses to restrict their vehicle but in terms of their SAE score. It's the same.

2ndly, Traffic Jam Assist steers and moves the vehicle at speeds under 60kmph. It's in the A4 and Q7 plus facelifted A3/S3 in some countries (UK, European)

To further prove this, here's a photo of the section in the new S3 manual.

Between 0 and 60 km/h, Congestion Assist combines acceleration, braking and steering guidance to help the driver safely navigate congested traffic. For speeds over 60 km/h, Adaptive Cruise Control takes over to maintain a set distance from the vehicle in front.

Czappa, thanks for making a point. It didn't make sense to me why it cant handle lower speeds, so the system has to be much more accurate at higher speeds.

Some other guys on the Audi world forum are say it's been not Included in some markets so people choose the A4 over the 3. All the gear is their, just not active. Surely it can be switched on in coding?? In AUS they have also not included Traffic Sign Recognition but heaps of owners have switched it on with the OBD Eleven.

It's obviously available in the UK. It's in the order spec sheet!

Actually Audi and Tesla share the same level of autonomy

They don't. They share similar levels of driver assistance, not autonomy.

The Tesla is cabable of fully autonomous driving; input a destination, and it's capable of self driving to the destination with minimal levels of driver input, using GPS mapping to drive the route. Push a button on the remote and it will even drive in/out of your garage. All hands off with no driver input.

No Audi is capable of that in any country (they have one German test A7 which is their autonomous development vehicle)

What audi does have (and is clearly stated in their manual) is a number of driver assistance devices/programs which provides additional levels of safety/and assistive driving skills:

ACC
Stop/Go
Lane Assist
Traffic speed sign recognition
Automatic lighting
Parking Assist

None of these are packaged together to provide hands-off autonomous driving (the closest is parking assist, but that still needs driver input). Only speed sign recognition and automatic lighting have any link to GPS mapping.

I agree that all of these components are elements of what's required to implement autonomous driving, and some of them can be implemented through software, even if not originally specified - (I turned on speed sign recognition on my A7 using Vagcom)

In slow moving built-up city traffic - or jams - only start stop assistance is available, since that uses the forward view radar sensor. For anything else (like lane assist) the front mounted camera has to look at the roadway ahead of the vehicle in order to identify the traffic lane. It can't do that if it's forward field of view is blocked by the car in front.

I would love to have autonomous driving capability in my Audi, it's just not there yet, and you can't just code it in.

To get back to the OPs original question regarding automatic start/stop in traffic, if you have ACC fitted, then this feature is available as standard. You enable it once using ACC, and the car will then stop and accelerate in start/stop traffic automatically (without you needing to touch accelerator/brakes or ACC controls again)

Why do they then market it as the following then. To me, That's more just ACC.

Traffic Jam Assist is not just ACC. It's ACC and Lane Assist working in tandem at speeds under 65kmph to keep the vehicle in lane and moving in congestion. This is in the new UK Cars.ln Australia it is not, as the Lane Assist which is needed to make Traffic Jam Assist work is not active until after 65kmph.

I don't need to read the manual.
I have these features on my 2016 S7, I use these features on my S7, and l know what the capabilities of the system are. Autonomous driving is absolutely not one of them.

But feel free to try it on your car, while sitting on your hands.........

This makes interesting reading for anyone wanting Audi's take on autonomous cars:

Actually, it isn't. The moving in and out of garage aside, the functionality in the Tesla is pretty equivalent to that in the A3 with the right options. Just like in the A3 too, you need to have your hands on the wheel in the Tesla too. It does lane assist and ACC, same as the A3. As an extra, it can change lane by itself when you indicate, and future models will have the ability to change the cruise control speed based on the traffic sign reading, but this isn't in consumer models yet AFAIK.

Here is a video clip of an autonomous Tesla in action:


If you think any Audi available today, outside of an R&D program, is capable of doing this, let me know. I'll buy one tomorrow, or get someone to Vagcom my software to make it available.

Again ACC is not the same as traffic jam assist, your S7 does not have traffic jam assist, again as I have said. It's only in the A4, Q7 and the new A3 with it optioned up. Again it's the ACC and Lane Assist working together at speeds under 65kmph to Steers and Move the vehicle in congestion.

It proves nothing, he's driving in a straight line, and can't go further that about 100 meters without manual steering corrections.

My 2016 S7 does this.

Your joking right?? Did you not notice the car was making steering corrections and the Active Lane Assist enabled when he was doing less then 65kmph?? He is only touching the wheel because your required to make driver input after 12 seconds.

RAF_S7 you just said a few posts ago that only ACC works in slow moving traffic, that video which explains traffic jam assist clearly says that Lane Assist is apart of Traffic Jam Assist. So if Lane Assist in your s7 does not work in slow moving traffic (like you mentioned earlier) then no you do not have Traffic Jam Assist.

Were codes ever found for enabling Traffic Jam Assist on Facelift A3/S3 ?
You need more than just codes. Has your car got s-tronic and is it fitted with Adaptive Cruise Control? Both are required for the ACC to work and stop the car properly in a traffic jam. My A3 has both and the system works fine.

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.

Wanting to know the same! 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.
