2019 S5 issues

Hello all- I just jumped my 2019 S5 after it was dead for about 3 weeks. Upon startup im getting a differential fault, a check engine light, and the SOS feature not working

Also I’m able to get Bluetooth and have the phone charge through the main usb port.. but when I try to connect to CarPlay through the Audi Smartphone feature every option is grayed out and not able to connect. Does anyone know what these issues could be?
