2Q0 907 572 AA Cruise Control to ACC retrofit - Ibiza 2022

a) In my oppinion the Engine have incorect coding.
Can you tell me why is changed Engine coding byte 5 from 24 (Front Assist) with 74 ?

Adresse 01: Motorelektronik (2D2D2-DLAC) Labeldatei: Keine
Teilenummer SW: 05C 906 032 J HW: 05C 907 394 D
Bauteil: R3 1.0l TFS H01 2363
Revision: 42101001
Codierung: 0125001223 24 0D0810000000000000000000000000000000 genuine
0125001223 74 0D0810000000000000000000000000000000 actual coding
Betriebsnr.: WSC 31414 790 00200

The right coding is
0125001223 64 0D0810000000000000000000000000000000

64 means (ACC FtS or ACC S&G)/ DSG with ESC High.

1. 2Q0 614 517 AQ ESC_high coding is ok for DSG + ACC (10009002, 10009003, 10009007, 10009008).
2. What exactly causes FAULT_ESP_CONS_ACC? - ACC incorect coding.
3. What causes SCL_ACC_Anhalteweg_Error in the ABS? - ACC incorect coding.
4. Is FAULT_CODING_RADAR_POWER_REDUCTION definitely a wrong coding bit in address 13, and does anyone know which coding setting controls this? Here is neccessary to check if in Adaptation, Radar_power_reduction: 38

b) Address 13 (ACC) is necessary to be analized separately.

Thanks a lot for your help.

The incorrect coding in 01-Engine had already been found and corrected previously, so that part was already OK.

The remaining problem was indeed in Address 13 – ACC, specifically the Radar_power_reduction adaptation channel.

After correcting this adaptation, the errors disappeared and ACC / Front Assist are now working correctly.

Thanks again for pointing me in the right direction!

I'm glad I could help. It would be useful if you posted the full Autoscan now (with the car running).
