This is the service and repair manual for the 2027 Audi S8, the performance version of Audi's flagship sedan and one of the most systems-dense cars in the range. The manual is built for that: alongside the V8 powertrain, cooling and driveline work, it documents the air suspension and active chassis control, the braking system, the driver-assistance sensor set and the module network that coordinates them, with coding and calibration requirements noted where a repair will not be complete without them. Torque values, capacities and wiring routing sit with the procedures that need them.

- 4.0L V8 (DWKA) Turbocharged Mild Hybrid EV-Gas (MHEV)

Known issues on the 2027 Audi S8. No recalls are on federal record for this model year, and no complaints are logged with NHTSA against it. The S8 is a very low-volume car, and combined with how recent this model year is, that means the federal record simply has nothing in it yet — absence of data rather than evidence of soundness. In the shop that argues for discipline: pull the stored fault data, check module communication before condemning components, and follow the diagnostic path to a measurement, because on a car with this much electrical content symptoms rarely point where they seem to.
The engine and trim above are carried forward from 2024, the most recent model year confirmed in detail; Audi's erWin parts portal lists this chassis continuing into 2027, so exact trim naming and output should be confirmed against your own build sticker and VIN. Everything else — service intervals, fluid capacities, component locations, wiring diagrams, calibration notes and the full removal and installation sequences — is documented here for the 2027 S8.
