We list the A4 across five generations: B5, B6, B7, B8 and B9. Engines include the 1.8T, the 2.0 TFSI, the 3.0 V6 and TDI diesels, with front-wheel drive or quattro.


Your 2022 Audi A4 is from the A4 B9 generation, which covers model years 2017–2025. 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 2022 model year.
Check the model year on your VIN: on a 2022 vehicle the 10th character of the 17-digit VIN is “N”. 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 4 years old, a 2022 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 A4, 2018 Audi A4, 2019 Audi A4, 2020 Audi A4, 2021 Audi A4, 2023 Audi A4, 2024 Audi A4, 2025 Audi A4.
