Traffic Jam Assist

[GeeMoney]

ALG can be activated via VCDS in earlier cars as can headlight assist and other stuff. TJA is not confirmed activated on any cars up until now and there is conflicting stories concerning it. Best read this thread from day one and the coding thread from day one and this is all explained at different times in those threads.

Maybe I can get a dump from an Audi A3 with TJA enabled.
It's also build on the MQB platform, right?
Does it make sense to get this dump?

The modules might not be exactly the same but it wouldn't hurt.

Ok, the A3 owner has VCDS, what exactly do we need? I request a full dump of the long coding for module A5, right?

I got this:

Address A5: Frt Sens. Drv. Assist (R242)       Labels: 3Q0-980-65X-A5.clb    
Part No SW: 3Q0 980 654 G    HW: 3Q0 980 654 
Component: MQB_B_MFK     H06 0231      
Coding: 0403070300000401012223448048A90098000E200080 
Shop #: WSC 06314 790 00021    
ASAM Dataset: EV_MFKBoschMQBB 001001    
ROD: EV_MFKBoschMQBB.rod    
VCID: 3B203F9DE3EC5E1F38B-806E

In my simple reading, it seems that this module has 0231 firmware which makes sense, and that could mean that the long coding might be our golden ticket?

well it looks like it's 9 different bytes than mine (going on every 2 digits is a byte in hex), but also wouldn't there be a difference in the ACC module as well?

Not sure, NZ_GolfR thinks also adaptation channels might be different but i will get the adaptation channels not before this sunday.
Could it be of any harm for you to make the long coding the same and test if TJA becomes available? (I don't have any clue how VCDS works, just acting as a man in the middle here)

could mess up the front assist or camera, I don't know though, or it could change some of the options I have that the Audi might not have, I just posted mine so people in the know would have more codes to look at

This is weird, l spoken to someone who has picked up his my18 Tiguan and he said it has TJA. And my dealer has confirmed it from vwa and some of the my18 Tiguan they have delivered.

Hi All, as quoted, I took delivery of my new MY18 162TSI (fully loaded) in Australia last week and I can confirm that it has both ALG and TJA.

I think there is some confusion on when/how it actually works and it is different to the Audi system - we need to acknowledge that TJA operates within the limits of the ACC, our Tiguan has a 3 second stop/go function which means you will always have to manually resume if stopped for a long period.

When I tested this I was on an 80km motorway with ACC set, the traffic slowed below 60km and TJA took over by continuing to steer, the ACC remains on as does the Lane Assist with ALG, both icons remain GREEN on the dash to a complete stop... If this stop is long it still requires the driver to manually resume (same as ACC), this is done simply with a light touch of the accelerator or press the resume button on the wheel - the TJA system then continues to steer/accelerate/brake again from standstill by following the car in front.

It's a great feature, I did notice it doesn't activate on suburban roads, and seems ACC needs to be set high or needs to meet certain conditions to operate as TJA.

I hope this helps settles any concerns... Cheers!

Strange as I am sure Hugo_nz said the update to enable TJA VWNZ loaded on his removed the 3 second limit, maybe he can confirm.

Yes and you should be able to activate it below 60km/h also I believe. Sounds like normal ACC with ALG functionality.
