The A5 coupe, Cabriolet and Sportback are covered across two generations: the 8T (2007 to 2016) and the F5 (2017 onward), plus the newest models. Most cars use 2.0 TFSI engines, with V6 and V8 power in the S5 and RS5.


The 2018 Audi A5 belongs to the second-generation A5 (F5), built for model years 2017–2024. Most procedures are shared with the other years of this generation, but engines, options and wiring changed from year to year, so the manual is made for the 2018 model year.
Check the model year on your VIN: on a 2018 vehicle the 10th character of the 17-digit VIN is “J”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 8 years old, a 2018 vehicle is usually past its basic warranty. Typical jobs at this age are brakes, suspension parts, fluids, the 12V battery and diagnosing sensor faults with the factory wiring diagrams.
Same generation: 2017 Audi A5, 2019 Audi A5, 2020 Audi A5, 2021 Audi A5, 2022 Audi A5, 2023 Audi A5, 2024 Audi A5.
