This service and repair manual covers the 2026 Audi S5 Sportback, matched to the S model in the four-door Sportback body rather than shared across the whole A5 and S5 family. The turbocharged V6, its cooling and charge-air routing, the quattro driveline, the S-specific brake and suspension hardware and the control modules behind the drive modes are all documented with diagnosis, testing, removal and installation, torque specifications and wiring routing kept together with the steps that need them.

Known issues on the 2026 Audi S5 Sportback. No recalls are on federal record for this model year, and no complaints are logged with NHTSA against it. That is an early-life record and nothing more — the cars have not been in owners' hands long enough for repeat faults to reach either dataset, so it should not be read as a reliability endorsement. Practically, it means starting from the symptom every time: use the vehicle's stored fault data and the manual's diagnostic path, and confirm the engine code before you trust a specification from anywhere else.
The engine and trims above are carried forward from 2024, the most recent model year confirmed in detail; Audi's erWin parts portal lists this chassis continuing into 2026, so exact trim naming and output are subject to confirmation against your own build sticker. Everything else — service intervals, fluid capacities, component locations, full wiring diagrams and the torque figures that go with each procedure — is here for the 2026 S5 Sportback.
