The A6 is Audi's executive sedan, covered from the 1994 C4 through the C5, C6, C7 and C8 generations. Engines range from four-cylinder TFSI and V6 TDI units to the supercharged and turbo 3.0-liter V6.


The 2025 Audi A6 belongs to the A6 C8 generation, built for model years 2019–2026. 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 2025 model year.
Check the model year on your VIN: on a 2025 vehicle the 10th character of the 17-digit VIN is “S”. 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 1 year old, a 2025 vehicle mostly needs scheduled maintenance, software and battery checks, and correct procedures for the newer electronic systems (ADAS sensors, calibrations and module programming).
Same generation: 2019 Audi A6, 2020 Audi A6, 2021 Audi A6, 2022 Audi A6, 2023 Audi A6, 2024 Audi A6, 2026 Audi A6.
