2018 BMW M6 Gran Coupe Service and Repair Manual

This factory service and repair manual for the 2018 BMW M6 Gran Coupe is not a broad book, because the car it describes is not a broad model line: one four-door sedan body, one trim, and a turbocharged 4.4L V8 with double overhead cams running on gasoline. Everything downstream of that follows from it. Clearances, torque sequences and diagnostic routines are stated as single values rather than as tables of variants, and the wiring diagrams show the equipment this sedan actually carries.

Known issues on the 2018 M6 Gran Coupe. What the book is for on this car is the routine that a turbocharged V8 sedan eventually needs. It sets out the induction, fuel and ignition specifications, the cooling system data, and the torque values for the engine's fasteners; it then covers transmission and driveline service, brake and suspension work, steering geometry, and the climate system. Body electrical coverage is drawn as circuit diagrams rather than as block sketches, so a dead accessory can be followed from supply to ground without guessing at the harness.
