Side assist + Rear traffic alert activation

I have the codings but u need to flash the hardware to your vehichle in order for it to work and that flashing cant be done with an OBDeleven, also a calibration needs to be done as well. 

Hi,

still me, after some time I decided to take the risk/fun and order all the components needed to retrofit the side assise / blind spot / rear allert in my Audi A3 40 TSFIe (2021).

After several months of studying various websites and retrofit kit manufacturers, I managed to reconstruct more or less the steps to activate it. In the midst of this discussion, let's omit the calibration for simplicity, as I have already found someone who can do it with the specific calibration kit from Audi.

These are the step I found:

1) GATEWAY
Register 3C and CF modules

2) Control unit: 03 Brakes (ABS)
Long coding:
Byte 18 activate bit 3 (already ON in my car)
Byte 30 activate bit 4 (already ON in my car)
Adaptations:
-Delay management:
Rear cross traffic assistant: Not activated --> Activated

3) Control unit: 17 Dashboard
Long coding:
Lane change assistance: No --> Yes
Lane change assistant, BAP distance: No --> YES
Lane retention assistant, BAP distance: No --> YES (Not sure about this!)

4) Control unit: 5F Multimedia
Adaptations:
-Vehicle function list BAP:
SWA_0x1A: Not activated --> Activated
SWA_0x1A_msg_bus: Not activated --> Terminal 15
-Vehicle menu operation:
menu_display_lane_assistant: Not activated --> Activated
menu_display_lane_assistant_over_threshold_high: Not activated --> Activated

5) Control unit: A5 Driver Assistance
Long coding:
SWA: Not_coded --> Coded
blind_spot_detection: Not_coded --> Coded

6) Control unit: 42 Driver Door
Long coding:
SWA: not_active --> active

7) Control unit: 52 Driver Door
Long coding:
SWA: not_active --> active

8) Control unit: 3C Lane change / CF
Long coding:
Something to activate, don't know what but apparently is self explaining

9) Control unit: 19 Gateway
Long coding:
PaCo_Rear_Cross_Traffic_Alest: not installed --> installed


Here what I found.

Please comments

My best

10) Control unit: 75 Telematics
Adaptations:
-Vehicle function list BAP:
Lane change assistance: Not activated --> Activated

Hello did you get it to work ?
I cannot find parametrisation file exactly for Audi A3 GY for rear radars with rear traffic allert. (i used DB_003C_7100_2G0_ME38_VW3800CNK0BA.frf)
Also power steering did not return me to line.
I also retrofitted 12K OPS parking (car was without parking)
Do you have some advice what can be there also done ?
(i use VCTool, it can compare also coding and adaptation from other car backuped)
Thx
