A guide to enable EU specific features for AU Spec Tiguans

[bestyjny]

I am assuming there must be something extra that needs enabling that I have missed? Even though it is showing as turned on it doesn't appear to be working as the lane assistance still doesn't kick in until I get over ~65km/h and still pinballing in the lane.

Also interested to know how you enabled Light Assist as well as I will like to try turning this on in my car as well.

I will hopefully have a copy of all the module backups later today so will PM them to you as well.

I posted my whole adaptation maps on Ross-Tech forum + in first post I described how my car is equiped. Just go and check

And another Tig 2017 EU scanned and published on RT forum.

This time, fully equiped, with everything* you can imagine (* - except webasto):

2017 Tiguan MQB, 2.0 TSI 220KM (CHHB)

Enjoy!

Emergency Assist/Traffic Jam Assist
[FONT=arial]A high possibility that it will work, given that Adaptive Lane Guidance can be/is enabled. Can be enabled via VCDS or OBDEleven.

UPDATE: It can be enabled via VCDS or OBDEleven. However, Module 44 - Steering Assist Module, varies between vehicles that are spec'd with Traffic Jam Assist/ Emergency Assist, and those that doesn't.

Tiguans that are "spec'd" for TJA and Emergency Assist have 7 bytes in Module 44.
Tiguans that are not "spec'd" for TJA and Emergency Assist only have 2 bytes in Module 44.

I still need more scans from other people, especially those that have TJA, to confirm my findings.

I'd love to get an idea of what I need to do to enable Traffic Jam Assist.

Do you need an export from me or is it something I can delve into myself?

Any reference or guide I can look at first?

Thanks,
Shane.

Yes you are. Lane Assist only works above speeds of 65km/h. It requires separate coding in order for it to function under 65km/h, and also for the ACC to restart automatically beyond the 3 second grace period. I will hopefully upload a video of both Emergency Assist and Traffic Jam Assist in action if I am successful in my coding.

Peanut, you talk of LANE ASSIST where the question asked was:

Awesome. Great to hear that Adaptive Lane Guidance can be enabled. Correct me if I'm wrong, but if you have ACC and Adaptive Lane Guidance, then you could pretty much achieve TJA without additional coding, with the caveat that you'd need to resume the ACC after being stopped for 3 seconds. The car would start and stop automatically (under 3 seconds) and steer itself. So the only difference with TJA is that it would resume beyond the 3 second stationary time. Am I missing something?

I'm going to have a guess here... ACC (car accelerates and brakes itself) works at all speeds. But Adaptive Lane Guidance (car steers itself) only works at speeds above 65km/h. TJA would require ALG to work at all speeds.

EDIT - Having just read a quote from the UK manual, I'm going to have to disagree with myself here I think ALG works at all speeds and so it would seem that TJA = ACC+ALG.

My understanding is slightly different.

Lane assist works at speeds above 65 km/h but Adaptive Lane Guidance, and Traffic Jam Assist only work at speeds below 65 km/h.

Think of it this way. TJA, by its very nature, is meant to help in situations of stop start low speed traffic. Below this speed it's designed to work. Above this speed you're clearly no longer in a traffic jam so TJA is disabled. You still get Lane Assist though above this speed.

Adaptive Lane Guidance, and Traffic Jam Assist only work at speeds below 65 km/h.

I thought that ALG was what keeps the car centred within the freeway lane markings (whereas Active Lane Assist only intervenes when you're about to cross a lane without indicating). So I thought it was for freeways not low speed.

EDIT - Actually, I think ALG works at all speeds.

Lane assist works at speeds above 65 km/h but Adaptive Lane Guidance, and Traffic Jam Assist only work at speeds below 65 km/h.

Perhaps ALG works at all speeds. From the UK manual:

Traffic Jam Assist function
At speeds under 60 km/h (35 mph) Traffic Jam Assist can maintain a time interval, set by the driver, to a vehicle in front, and help the
vehicle to stay in lane ⇒ .
The system automatically controls acceleration, braking, steering and, if required, will decelerate to a stop behind a vehicle that is
stopping, and then drive away again automatically.

Adaptive Lane Guidance
When adaptive lane guidance is active ⇒ Activating or deactivating adaptive lane guidance , 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.

Possibly, but TJA is definitely only low speed.
