Retrofitting of Heated Steering Wheel X247

[vidziuslt]

I decided to try retrofitting the X247 facelift with a heated steering wheel. I bought a new steering wheel cover with a heating on/off button. I connected the button to the airbag contact ring. Now I need to buy a new steering wheel with a heating control module inside. I found that the original steering wheel control module has the part number A0999001804.
Can anyone with access to the parts catalog check which module is an alternative to the original? I have two options: A0999001904, which was replaced by A0999003204.
Or another option - A0994648709, which looks the same and has two outputs for heating the steering wheel
My X247 steering wheel has a simple Distronic system, without any active distance control packages.
And one more question. What other modules, besides the steering wheel module, do you think I need to code? Maybe someone could share the codes?

I'm trying to move on. I installed a new electronic steering wheel module A0999003204 and connected it to the steering wheel heater. Now everything is connected correctly. Now all that's left is to check the coding. So I tried to figure out where and what I needed to change. I discovered that it was impossible to create a variant coding using XENTRY on SCM (SCCM177) or SAM modules.
I also couldn't find anything in the SCCM177 module with DTS Monaco. It's empty. Or maybe it's a corrupted SMR-D file?
Maybe someone knows more about coding the heated steering wheel?
