A guide to enable EU specific features for AU Spec Tiguans

Possibly, but TJA is definitely only low speed.

Yes, and the videos on YT illustrate TJA below a threshhold speed of about 67KPH.

Lane assist does what you describe above as well, let's clear up some terms as I do believe they are not being used accurately enough and that is leading to confusion by all....

Lane assist....my car has this and it is activated and works above 65KPH. It is meant to give a warning and nudge the car back into the lane.

Active Lane Assist...my car does not have this

Adaptive Lane Guidance....my car does not have this

Active Lane Guidance...my car does not have this

Yes, getting clarity on all these subtlety different terms would be great. You've confused me again though!

I thought the difference between Lane Assist and Active Lane Assist was that the former only provides a warning, it does not intervene. Whereas the latter will take control of the steering. Both only function at 65km/h+. So what you call "Lane Assist", I've been calling "Active Lane Assist".

Active Lane Guidance - What is that?!

I could be wrong as well but the terms I listed above are what I have seen written and I don't know the official VW speak surrounding them. My car with lane guidance if left to itself will wander to the left and align itself to the fog line on the left hand side of the road, it will even drive through a highway bend unassisted. It gives a warning if there is no indicator used and it is steered across a lane marking line, what is assistant is at play here? Terms need to be clarified before discussions become more confused so let's do it. The Passat, and Skoda Superb both have TJA, does anyone know where a PDF of both could be had?

I've had a quick look at the Australian-issued manual and it doesn't talk about Active Lane Assist vs (Passive) Lane Assist, or Active Lane Guidance vs Adaptive Lane Guidance. Just "Lane Assist" and "Adaptive Lane Guidance". Can I have a stab at some simple definitions?

Lane Assist = Actively intervenes with corrective steering if the car is at risk of leaving the lane. Capable of aligning to a lane marking and following a bend in the freeway but does not align the car between the left and right lane markings.

Adaptive Lane Guidance = Provides permanent assistance to keep the preferred position between two lane markings. (There has possibly been some mix-up of language across posts/reviews because ALG is described in the manual as part of the Lane Assist system rather than as something completely different).

Traffic Jam Assist = Controls acceleration, braking and steering at speeds under 60km/h. (Manual: "An extension of the lane keeping system (Lane Assist), and combines this function with the Adaptive Cruise Control").

Well ignore all the above it is a load of old rubbish and I will delete it after I have finished posting this amended version.

My car has these options copied directly from the screen and including brackets, etc

Lane Assist (lane departure warning sys.)

Side assist (Lane change assist system)

Adaptive Lane Guidance....my car does not have this

Active Lane Guidance...my car does not have this

I should never go from memory I suppose and now I will stand in the corner with the dunces hat on.

2 YouTube videos on VW Driver Assistance systems

Hi All,
To bring a standard understanding to the variety of terms used by VW and others regarding the various features available on VW cars I have found these videos from YouTube with date published.

I hope this helps our collective understanding?

The only person(s) wearing a dunces hat should be whoever at VW thought that allowing so many variations between safety features among and across models of the same generation was a good idea.

Active Lane Guidance.

I'd love to know what this "Active Lane Guidance" feature is. Anyone?

I'd love to know what this "Active Lane Guidance" feature is that we do not have and that is not mentioned in the manual as far as I can tell.

It is a term I saw written somewhere or I think I did, nothing more than that and if it is incorrect we can agree to drop it altogether.

Hi Latearrival,

My experience with "active Lane Guidance" is in the Lane Cove tunnel in NSW. It has sweeping bends and a speed limit of 80 Km/Hr.

I lightly keep hold of the steering wheel. I have set the ACC to 80KM. I then let the car steer and accelerate or brake according to the traffic ahead.

I can feel the car turning the steering wheel into the corner when I approach the side of the lane. It slowly moves across the width of the lane until it "sees" the lane marker on the other side. It then gently steers keeping the car in the lane. At no time did I give any steering input to the car.

I have the impression that the car will slowly "zig-zag" across the lane as you travel down the lane.

The above is from my stock standard Tiguan with DAP.

The reason it was working was because I was travelling at "highway" speed. (Above 65 Km/Hr)

What we want to do is "activate" this feature below 65 Km/Hr.

I hope the above helps.
Regards,
David

Thanks David. What you've described is just "Lane Assist" without Adaptive Lane Guidance. For TJA to work, I think we need low-speed Adaptive Lane Guidance too.

Sorry Ozsko, my fault. I thought in an earlier post you meant that you'd seen 'Active Lane Guidane' on a screen in your car.


I feel I've got a bit of clarity now. At least for an hour or two


With DAP we have Lane Assist (takes corrective action if the car begins to drift over one lane marking, and can even follow one lane marking) but without the Adaptive Lane Guidance extension (needed to maintain position within two lane markings).


Traffic Jam Assist needs both ALG and ACC. So if we can enable ALG with VCDS or OBDEleven, we may be able to enable TJA too. Fingers crossed.

That's what I'm hoping!

This is taken from the owners manual page 227 first parargraph:

Traffic jam assist can be switched on or off together with adaptive lane guidance (my italics) -> page 224 by pressing the menu button and the vehicle settings buttons on the infortainment systems -> page 76

So we wander over to page 224 and this is what it says:

Using a camera in the windscreen, the lane keeping system detects lane markings on the road. If the vehicle gets too close to a detected lane marking, the system warns the driver by taking corrective steering action (VW's Italics) and helps keep the vehicle in lane. The corrective steering action may be overridden by the driver at any time.

When the adaptive lane guidance (my itallics) is active -> page 226, the lane keeping system does not just provide assistance when the vehicle is at risk of leaving the lane. If the system detects both lane markings to the left and right of the vehicle the function provides permanent assistance while the vehicle is in motion.

The system adopts the preferred position within the lane in which the vehicle is travelling. For example, if the vehicle is being driven slightly off centre in the lane, the system will learn to adopt the new position within a short period of time.

No steering intervention will occur if the turn signal is switched on as the lane keeping system will assume that the lane change is deliberate.

Lane Change System (side assist plus) - ** To clarify, this is what we call blind spot monitoring**

If the vehicle is equipped with a lane change system (side assist) -> page 229 and the system is activated , the driver is warned by corrective steering intervention when changing lanes during a possible critical situation (information level, warning level). This also occurs when the turn signal is activated in the corresponding direction. If the steering intervention is overridden by the driver, the steering wheel vibrates to give an additional warning.


Lane Change System Page 229

The lane change system uses radar sensors to monitor the area behind the vehicle -> page 39. The system measures the distance and the difference in speed to other vehicles....blah blah, it goes on to describe what we call blind spot monitoring


So there you have it straight from the horses mouth.

Edit above to clarify what VW calls side assist plus. This stuff is bloody confusing TBH, what with local terms, VW not being consistant with terms and the way the book has been written

[Delewin]

Ha. And I thought activating these mods were going to be easy. The hard part so far is trying to work out just what we have to start with and then what are our options.

The only thing I am totally clear on is the DAP is an absolute must to even start to take advantage of some of the possibly available add ons.

I hope the experts in this forum who are currently activating their cars can at least send some demos from really basic tricks and leave guidance for long coding or complex tasks for beginner like me to learn how to hack in the car please ??????
