not 100% sure , I have the same model as you , lower milage but still the same variant, when I called the insurance company to make my claim they asked me what the damage was after which they said they would write it off based on the amount of damage and the approx cost , but, they would need to get an upto date valuation of my car, initially they quoted me £5-6k as a write off payment, I then told to think again and told them what specific model it was , and all the details, they then changed there tune and said approx. £9k , they said there first quote was based on a base line model A4 with 100k miles, mine wasn't that by any means.
anyway , insurance engineer also confirmed the same value when he came out to assess the damage etc , so worth keeping that in mind that if they do want to write it off don't let them value it as a base A4 model otherwise you'll get a silly cheap price offered.
