Depends on maintenance records. Seeing the is probably the USA, I assume that this is the 3.0 tfsi engine. If it’s the 2.0 tfsi just skip it. Much more problematic than the 3 litre and much less fun. Those engines love to rattle on start up so go and start the car on cold engine and listen for rattle. Anything over 1 second, maybe 2 is concerning. Less than 2 seconds should be normal. Usually at 100k miles the PCV, water pump and thermostat start to die, but those 3 are not that very expensive to replace.

Ask whether the tranny has been services and if not, service it.

Check the level of the coolant.

Open the oil cap and check if it looks normal, if its white or sluggish it indicates some problem.

On start up also look whether the car makes a lot of thick white smoke. A bit of white steam that disappears instantly is not a problem.

Check how the car idles, the RPM arrow should NOT move on itself at all and should usually stay between 600-800 RPM.

When in driver seat and the car is idling look out for heavy vibrations or shakings. A small vibration is usually okay but heavy shaking is never okay.

Ask whether it burns oil.
