2021 BMW M5 Service and Repair Manual

This factory service and repair manual for the 2021 BMW M5 belongs to a two-trim year, Base and Competition, built on the four-door sedan body with the turbocharged 4.4L DOHC V8 on gasoline. The mechanical package is common to both, so specifications, clearances and torque values carry across the pair, and where the Competition differs it differs in calibration and equipment, which is territory the wiring diagrams, control module descriptions and diagnostic routines handle rather than the engine chapters.

Known issues on the 2021 M5. One recall stands on the federal record: a small portion of the rearview image can be obscured, so the picture the driver relies on when reversing is not the full view behind the car. Two owner complaints follow, one on the power train and one on the exterior lighting. Both point at circuits rather than castings, and the manual's body electrical material, meaning camera and lamp wiring diagrams, connector views, ground points and the step-by-step fault tracing that goes with them, is where that work gets done.
