Hey. Just picked up an A7 3.0 TDi 2012 last night and drove it home(a few hours of driving) and I've been driving it to and from work with no issues at all.

Then, when I'm looking for an open parking spot, going around 10 km/h, I get these errors: Start/Stop, ACC&Brake Guard unavailable.

I went to my garage and did an Auto Scan with VCDS, but I'm not sure what the problem is. I'll post the scan results down below.
Any help at all would be very welcome!

Is anything in front of the sensor? Dirt, snow, a bag, paper, big bugs, your plate all can block it and disable it.

Otherwise check the wiring.

Nothing in front of radars or windshield camera.
Will check the wiring later today, thanks!

Looks like you have no communication with the front sensor of the car. The plug could have came out or you have a bad sensor or wiring. Unfortunately, I have just went down this rabbit hole with my top camera. The dealership's only solution is to throw parts at it until it works. I would take the bumper off and try wiggling wires and see if everything looks good, then troubleshoot from there.
