2026 Audi RS5 Sportback Service and Repair Manual

This is the service and repair manual for the 2026 Audi RS5 Sportback, written for the RS car rather than adapted from the standard A5 with a few pages bolted on. That distinction matters where it always matters on an RS: the turbocharged V6 and its cooling and charge-air plumbing, the driveline and rear differential, the RS-specific braking and suspension hardware, and the control-module calibration that ties the drive modes together. Diagnosis, removal and installation, torque specifications and wiring routing are all here with the steps that use them.
