for B10E7 F0 [009] - Disconnected [FAULT_CIS_TSK_IRREV_FAIL] just do "bus rest" eg. switch off, wait 1min, switch on and then delete error on STG-13

"K" 0402 is latest for this radar.

I try this no possible my problem is in ABS coding or no support acc stop and go, I post coding !
My oreginal fec is 10003100 i change to 10003300 ACC with Stop and Go 
DTC B10E7F0 storred and aac no found

Try this coding on ABS after you have flashed and coded radar:
1A 07 62 91 20 22 0A 72 00 77 06 03 01 CB 24 58 46 04 50 00 60 80 24 F0 38 49 00 20 C0

This will activate "With Front Assist/AEB, with ACC+S&G (Stop & Go) [8T3/8T8]" on byte 24, bits 1-4

I'm not sure if 5Q0 ABS module have support for "Stop & Go" at all and you don't have EPB either.
Your ABS module have old SW version as well, if this coding will not work maybe you can consider update it to the latest one, maybe they have enabled support in later versions (best if you google it for more info).

But prior flashing, backup all coding's and adaptations values since they will be lost (zeroed) after flashing.
You will need to perform basic settings on ABS and Steering Assist after flashing:

Module 03
1. Restore coding
2. Basic setting: IDE05146-ENG114972-Basic setting of ESP sensor unit,
3. Basic setting: IDE03650-ENG114972-Basic setting for brake pressure sensor
4. Basic setting: IDE05334-ENG114972-Reset tire pressure monitoring display warnings
5. Set TPMS via radio (Car -> Settings -> Tyres - SET!)
6. Basic setting: IDE05335-ENG114972-Electro-mechanical parking brake function test

Module 44
7. Basic setting: MAS00815-Steering angle sensor
8. Basic setting: IDE05744-Steering angle sensor: initialization


Flash ABS only if you know all the risks!!!
