Audi=No fault code, no idea
To be honest, if its got that far then its not going to have head issues etc. If its not smoking, sounds happy, DSG changes smoothly on the paddles up and down, pulls away with no clonks etc. Has a service history for at least the first 80k miles........then its luck of the gods but in your favour i would think.
At that mileage anything could go from exhaust to disc's, engine to gearbox but chances are you will be fine. Its a good solid set up.

Many people are alive because its illegal to shoot them.
