Factory service and repair documentation for the 2027 Audi RS6 Avant in Performance specification — the RS estate, documented at the depth this driveline demands. The turbocharged 4.0L V8 with mild-hybrid assist is covered from routine servicing through to full overhaul: cylinder heads and valvetrain, timing drive, charge-air and cooling, lubrication, fuel and ignition, emissions and exhaust, plus the hybrid assist hardware and the control modules that manage it.

The engine code and trim naming above are carried forward from 2024, the most recent model year confirmed in detail. Audi's erWin parts portal lists the RS6 Avant continuing into 2027, which is what confirms service data exists for the badge, so exact trim naming and output for 2027 should be treated as subject to confirmation against build data.
Known issues on the 2027 Audi RS6 Avant. No recalls are on federal record for this model year, and no complaints are logged with NHTSA. On a model year this far forward that reflects the state of the record rather than the state of the car, and it is worth re-checking the VIN against NHTSA's campaign lookup before any safety-system repair. Practically, the service items that decide how an RS6 ages are brake and tyre condition, the cooling system's ability to keep up under sustained load, driveline fluid intervals, and correct re-adaptation of the chassis and transmission modules after work.
The chassis material is where an RS estate earns its own manual: air-sprung and adaptive damping components, the RS brake hardware including the ceramic option where fitted, wheel alignment specifications, and the driveline that sends drive to all four corners. Torque values, sequences and wiring diagrams accompany each of them.
