This factory service and repair manual for the 2015 BMW 640i xDrive Gran Coupe has one Base trim, one four-door sedan body and one engine to account for, a 3.0L turbocharged inline-six with double overhead camshafts burning gasoline, which makes it a description rather than a decision tree. Engine mechanical and its supporting systems come first, then the driveline, then the chassis and body, each with the procedures, specifications, torque values, wiring diagrams and diagnostics the work on them requires.

Known issues on the 2015 640i xDrive Gran Coupe. Most of what a shop needs here is numerical: torque values for engine and chassis fasteners, clearances and specifications for the inline-six, brake figures, and the suspension and alignment settings that have to be restored whenever a component is replaced. The manual prints them and pairs them with wiring diagrams of the car as built, so a circuit can be followed connection by connection. The diagnostic sections then work a symptom back through the system responsible instead of listing likely parts.
