Hi,
I have an A4 Allroad 2017 with the same engine, mine has only done 18,000 miles as yet,
but i will be changing the air filter myself when the time comes, there seems to be more things to remove
when changing the filter on this engine, the best advice i can give, is to just take your time, and don't break
any clips etc. i have always maintained all my Audi's myself, after all, if an audi mechanic can change it i'm
sure you will be able to, best of luck.
Brian.
