2019 BMW 640i Gran Coupe Service and Repair Manual

This factory service and repair manual for the 2019 BMW 640i Gran Coupe covers a four-door sedan with a single powertrain listing, a 3.0L inline-six that is turbocharged and double overhead cam on gasoline, and a single Base trim. Everything the volume contains is keyed to that one build, which removes the step of identifying which variant is on the hoist before a specification can be trusted, and lets the engine, driveline, chassis and body sections be read as one continuous description of the same car.

Engines covered

• 3.0L inline-six — DOHC, turbocharged, gasoline

Body styles covered

• 4-door sedan

Trims covered

Known issues on the 2019 640i Gran Coupe. The value of the manual on a late car of this kind is in what cannot be guessed: the pressure a fuel rail should hold, the clearance a valve train is measured to, the torque a suspension link is tightened to at ride height, the resistance a circuit should read at a given pin. Those figures are given for the engine, transmission, final drive, brakes, steering, suspension and body electrics, each attached to the procedure and the diagnostic test that calls for it.
