TJA - Traffic Jam Assist on pre-FL Octavia

Hello,

I was searching through the forum and found out, that to enable traffic jam assist (TJA) function you need "only" to flash correct dataset.

I also found out, that you need to have Lane Assist (3Q0), ACC radar (5Q0 or 3Q0? I think, that we need 3Q0, right?) and have automatic transmissions (which is stated in manual of Superb).

Can anyone answer me my questions, which are:

Do I really need 3Q0 ACC radar for TJA?

I have 5Q0 radar (pre-FL) and 3Q0 A5 camera (FL). I needed to set in A5, that I don't have ACC radar and in ACC, that I don't have camera and in ACC remove two CAN cables, which are only to communicate between ACC and A5 camera. I did this, because it looks like, that 5Q0 ACC radar and 3Q0 A5 camera is not compatible, but maybe I am wrong. Before the removing of CAN cables I was not able to get it working both (ACC and A5 camera). I have only three small issues with this: I can set ACC only up to 160 km/h, in virtual cockpit I can't see properly the animation of car in front of me and with speed below 25 km/h ACC disable itself with message "Use brake pedal". Beside of that, it is working correctly.

Do I need ABS compatible with ACC follow-to-stop for TJA?

Currently I have ABS only compatible with ACC for manual transmission (without follow-to-stop function).

Did anyone see pre-FL Octavia with 3Q0 ACC radar? 

I am asking, because I was thinking about changing the radar to 3Q0.

What everything I need to know before changing ABS module to correct one - with support of Follow-to-Stop function?

I mean like - do I really need "only" to change the module itself and that is?

Is there any additional cables needed? How can I get it to work after the change? I read somewhere, that I need to do something like "filling the pipes" via diagnostic.

I have Octavia 1.6 TDI DSG MY16 with a lots of retroffiting towards FL version.

Thanks for any help!
