Traction control and 4motion not working

[Kiveshomo]

T6 transporter got abs and traction control lights on 4motion not working.

Got my fault codes read and got the following codes:
4197- Rear left wheel speed sensor
8269-Databus
31343- Control module for all wheel drive clutch
25126- Implausible data received from Esp control module

After I got these codes I changed the speed sensor and the abs light went away but still got the traction control light and text saying ESC error. And also 4motion still not working.
Does anyone have any ideas what could be the reason causing these problems?

Oh and also sometimes it has problems with the start/stop system. Occasionally it says something like "error start stop" and then it would not work. Even though that does not really bother me since I've always turned start stop anyway.

Have you got coms with the AWD unit?

Can your code reader manage to communicate with the AWD control unit so you can extract fault codes and see live data etc.

Got fault codes read by a mechanic with vcds. Would it not show on the report? Those fault codes I listed are all that they got out of it.

Here is all that was on the report they gave me.

I'd start with checking why the AWD module has no Comms. Could be a blown fuse or a broken canbus wire or the AWD unit is fubar
