Traffic Jam Assist

[Rainesh]

This might be a silly question, but when you are using adaptive cruise control or TJA, does it always flash the brake lights when it's reducing the speed? Especially in city traffic.

Yes

Does flash mean ‘operate’ or ‘pulsate’

[PeteC]

operate

Hi Rainesh
I have a question
I have a pre-FL golf 7 (dec 2016) but I have changed the camera. Today I have a camera (year 2019) with hardware version H09 and software version 0272.
Can I have TJA just with OBD11 without VCP ? And, if yes, how ?

Thx

Hi,

No you need vcp for TJA.

Thx for your answer

My camera comes from a tiguan of 2019. It had the TJA functional but on my car it does not work ...


why do you need VCDS or OBD11?

You sure it had TJA functional? If so, then you need to change your ACC sensor for a facelift version.

Radar has component protection so just be aware that will need to be addressed if you swap it. Fec also need to be restored.

Maybe ..

Yes I think
How know if my ACC radar is compatible for TJA ?
You tell is necessary have vcds for coding the option after upload the parameters with VCP.. Maybe it's just necessary activate an option in my car with OBD11/VCDS for my new camera, do you think is possible ? and if yes which one ?

my ACC sensor :
5Q0907572G
hardware : H10
software : 0571

My brother has the TJA on his GOLF 7, his ACC sensor is :
5Q0907572H
hardware : H10
software : 0620

Is it possible with a VCP ?

First reparametrise the camera with vcp and then do the coding with obd11/vcp or vcds. What you prefer.

It seems that your acc radar is correct.

Try the parametrisation

thank you
yes I will see with the VCP
what is the coding to do with OBD11 after the vcp?

Hello guys.


I have a Tiguan 2019, with ACC, camera, etc.
I have VCP and VCDS.


To activate TJA, just upload TJA parameters through VCP, and then follow the steps below with VCDS?

A5 > Coding > Byte 16 > set Bit 2-3 to "08" (EA_Variant2)
03 > Coding > Byte 29 > enable Bit 5
13 > Coding > Byte 04 > enable Bit 2
09 > Login: 31347 > Adaption > Channel "Außenlicht_Blinker-Warnblinken_durch_Fahrerassistenz" > set to "active"



To upload the parameters, just use the Upload function and select the TJA file?


When you perform the procedure, will all settings in module A5 be maintained or reset?

You need to use guided functions and choose parameter upload.
It will not overwrite coding or adaptations.

Okay, perfect.
I'll try and put the result here.
Thanks!
