2017 Audi a6 quattro 2.0t

Post-accident where no airbags deployed. cars mmi, door lock, and hazards work.

No Crank, No start. Ignition button press is recognized as the key lights up when pressing but does not go into accessory mode

OBD-II scanner cannot communicate with the computer; even with the high beam, hazards, and brake activated to work around no ignition.

- battery and battery overload fuse replaced so not the cause of this

All fuses seem to be intact, had to replace serpentine belt because ac condenser pulley was shredded.

Please help! I am very stuck and would greatly appreciate it!
