2021 Audi S5 Service and Repair Manual
This 2021 Audi S5 factory service and repair manual is built around this exact model year and trim, so the torque values, wiring diagrams, and diagnostic steps you get are the ones Audi published for your car, not a figure borrowed from a similar-looking year. It covers the 3.0L V6 (CWGD) turbocharged gas engine under this S5's hood.

Known issues on the 2021 S5. Five recalls are on federal record for this model year. The first covers the rear seat belts: the automatic locking retractors can deactivate early, and an unsecured child restraint system can increase the risk of injury during a crash. The second covers the tires: rear axle misalignment left uninspected after an earlier recall repair may cause premature or uneven tire wear, increasing the risk of a crash. The third covers the tail light wiring, which can lack scuff protection so the wires become damaged in a rear crash, disabling the doors from being opened from the outside, causing a loss of hazard lights, and increasing the risk of injury. The fourth covers the rear suspension: a broken trailing arm lock nut may misalign the rear axle, causing a loss of control and increasing the risk of a crash. The fifth covers the back-over prevention display, where a software issue can leave the rearview camera screen blank, reducing the driver's rear visibility and increasing the risk of a crash. Owners have filed 1 complaint for the year and Audi has issued no technical service bulletins. The factory diagnostic and repair procedures behind each of those systems are here.
From a rear axle alignment check to tracing the tail light harness or confirming the rearview camera software fix, it keeps you on the OEM procedure and the correct specification for your specific 2021 S5.
