👍👍👍 this generation and model definitely claim a high spot among the best looking Audis ever designed

Yeah don't go back to that garage. And I'm definitely sounds like there's still air in the brake lines or the fluid level is not correct. Also check the position of the bleeder screw on your calipers they should be at the top. If they're not in that position then they could have installed the calipers backwards or upside down and that could also cause the lack of firmness that we like to feel when we hit the brakes

Appears to be adaptive cruise control. Any since it's on when you're parked and not in the car maybe you're can bus is not going into sleep mode? Since you don't have any dtc's visible by vcds. Then again I could be wrong our cars are goofy.

Possibly faulty or deteriorating battery or one of the corresponding modules. That would be my best guess. My car went crazy when my battery went bad and my alternator went bad. I replaced them and I had to code the new battery but then after that everything was fine.
