Default Electrical issue

I have a 2013 Audi s7, it was previously in a total loss accident. I had my front ACC sensor replaced and I was told to bring the car to the dealer to get calibrated. So I brought it, and they charged me $5000 to get it calibrated. So I told them I was not gonna pay and took the car from them. The next morning when I started the car my instrument cluster stayed black, as if it was off, my heat/ac controls don’t work and my steering column controls don’t work, is this a coincidence that it happened right after the dealer or did they do something to it? I checked all the fuses/ relays and everything is good. When I scanned it with a OBDeleven I got these codes
- lost communication with HVAC control module
- lost communication with steering column control module
​​​​​​- Lost communication with instrument panel cluster control module
