2020 BMW M5 Service and Repair Manual

This factory service and repair manual for the 2020 BMW M5 lists Base, Competition and Edition 35 Years against one body and one engine: a four-door sedan with the turbocharged 4.4L DOHC V8 running on gasoline. That arrangement makes the book easy to use in a bay, because engine, fuel, cooling and driveline procedures never have to be qualified by trim, and the areas that do vary between the three cars are set out with their own wiring diagrams and diagnostic steps.

Engines covered

• 4.4L V8 — DOHC, turbocharged, gasoline

Body styles covered

• 4-door sedan

Trims covered

• Base

• Edition 35 Years

Known issues on the 2020 M5. Three recalls are on record. Two concern the view behind the car: on one, part of the rearview image is obscured, and on the other the camera display shows no image at all. The third is mechanical, a damaged transmission wiring harness that can short and force the gearbox into neutral, cutting drive without warning. Two complaints are logged, one against the power train and one against the engine. Camera circuits, transmission wiring and engine management all carry diagrams and fault-tracing procedures here.
