The above captures things well - but to put it into words, you should strictly expect it to have had:
- 2016 PDI
- 2017, oil change service
- 2018, inspection & oil service / pollen filter
- 2019, oil change service / MoT / brake fluid / Haldex coupling oil
- 2020, inspection & oil change service / MoT / pollen filter
- 2021, oil change service / MoT / brake fluid
Nonetheless, "full" history probably amounts in Audi's eyes to a bi-annual oil change service. Many new cars left dealers with the Audi factory default of mileage-dependent (Longlife) servicing rather than the fixed interval annual service setting. So, you will probably find it unrealistic that a car has fully met the schedule above.
At 7k miles, I would be prepared to be flexible on some service items that were time rather than mileage-dependent. Arguably a 7k miles car that had followed the above would have been over-serviced... or just be a car belonging to me.
