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 2022 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 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.
