I am looking for help with my retrofit - Superb 2021; Virtual Cockpit, MIB3 infotainment . It was done some time ago, but it doesn't work properly from the start:

• side assist seems to work ok - it reacts on both sides.

• rear cross traffic assistant - not working at all (on the dash - error - unavailable). Usually not possible to tick on the dash; even if possible - each time I select "R" - beep + error on the dash.

Carscanner shows error:

U112300: Databus error value received
Parkhilfe_01::PH_Tongeber_H_verfuegbar. -> I was already asked if park buzzer works properly -> yes, it does.

I think that hardware shall be done properly, but something is wrong with coding. I googled a lot, but was unable to find coding for similar car to check it :/.

I found coding for 2016 Passat, but I doubt if this is the same:

[MQB] [Skoda SuperB] - Rear Cross Traffic Alert - Coding

Is anybody able to help me find the proper coding for Superb 3 FL (MIB3; VC)?

I normally use Carscanner, if needed I will borrow OBD11.

I can see a post in link Ross-tech topic:

My car:

ABS - byte 29, bit 7 is active

Module 76 - byte 3; bit 12 is not enabled. 

Screen from ODB11 - Parking Assistance (76):

I've coded that bit and I got big emotions - more than 50 errors occurred, even engine and transmission. I managed to clear everything, but something more is wrong :/. After coding, parking sensors became unavailable.

Are you able to help to find what more shall I correct?
