I just bought this car 2 days ago, knew it would need a little TLC with it having 210k miles, just trying to figure out what it might be, new to the audi scene.

When i’m driving and slightly accelerating it makes a buzzing/rumbling noise and it sounds like it might be the exhaust? and the headlights.. My high beams won’t come on and it throws “Adaptive Headlight error” or something like that. Any feedback would be appreciated!

Car buzzing/rumbling could be misfire. Likely causes are inconsistent fuel supply, inconsistent air supply, vacuum leak or carbon buildup.

High beams have nothing to do with Adaptive Headlights. The adaptive headlights system consists of motors inside the headlights that turn the projectors up/down or left/right depending on the position of the car or the wheels so that you see better. That is known to fail with time especially when the headlight cover is not sealed properly which causes water and humidity to get in there and cause damage.

High beam issues could be electrical but could be as simple as a bad bulb or igniter.
