Audi S4 -sport differential system fault

[kvalentino]

Hi , Audi S4 with “differential system fault“, need detect where is the fault
I think it is very likely that the module software is damaged (with this DTC in AWD module: "0325 - Internal Control Module Memory Check Sum Error"
The other one that doubts me is the ABS (the soft or coding). VCDS don't recognize the labels - Labels: None.
I see HERE that same ABS HW: 8K0 907 379 AN but with other SW: 8K0 907 379 CA is detected as labels: 8K0-907-379-V1.clb
And HERE the same HW y SW - 8K0 907 379 AN is detected as Labels 8K0-907-379.clb (In VCDS Labels folder, I have only the two files: 8K0-907-379-V1.clb and 8K0-907-379-V2.clb
I have checked the connectors and connection to the module and all are OK (+12V [30 &15], GND, CAN-H and CAN-L with oscilloscope)
If I take another 2nd hand with same HW & SW numbers, does it have to be long coding or can direct mout without coding?

Any help is welcome!

what year is it and do you only have the vcds? this will likely need a new dump putting in the module as it looks the the eeprom or flash is corrupt
