2021 Audi SQ8 Service and Repair Manual
This 2021 Audi SQ8 factory service and repair manual is matched to this exact year and trim, so the specifications and repair sequences it gives are the ones Audi published for your SUV rather than a generic figure borrowed from another model. Every SQ8 built this year runs the 4.0L V8 (DCUE) turbocharged mild-hybrid EV-Gas engine, and the manual covers it in full.
Engines covered
- 4.0L V8 mild hybrid (244 cu in) — DOHC, turbocharged, gasoline
Body styles covered
- 4-door sport utility
Trims covered
- Base
- Premium Plus
- Prestige
Known issues on the 2021 SQ8. Six recalls are on federal record for this model year. The first covers the rear seat belt automatic locking retractors: an unsecured child restraint system can increase the risk of injury during a crash. The second covers rear axle alignment that may not have been inspected after an earlier recall repair; rear axle misalignment may cause premature or uneven tire wear, increasing the risk of a crash. The third covers cracks that may develop on the surface of the engine cylinder bore, which may cause engine damage and a stall or an oil leak, increasing the risk of a crash or fire. The fourth covers a software issue that can leave the rearview camera display blank when the vehicle is placed in reverse; a blank rearview camera display can reduce the driver's rear visibility, increasing the risk of a crash. The fifth covers a software error that may cause the instrument panel display to fail, which can keep it from showing critical safety information such as the speedometer or warning lights, increasing the risk of a crash. The sixth covers a separate software error that may prevent the rearview camera image from displaying as intended; a rearview image that does not display reduces the driver's view behind the vehicle, increasing the risk of a crash. Owners have filed 3 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From tracing a rearview camera or instrument cluster fault to a rear axle alignment check or an engine cylinder inspection, it keeps you on the OEM procedure and the correct specification for your specific 2021 SQ8.
