2013 BMW 640i Gran Coupe Service and Repair Manual

This factory service and repair manual for the 2013 BMW 640i Gran Coupe deals with the four-door member of this family: a sedan body, a Base trim, and a turbocharged 3.0L inline-six with double overhead camshafts burning gasoline. Two extra doors change more than the shape. They change the wiring that has to reach them, the latches and glass they carry, and the structure around them, and the manual's body and electrical sections are written for that four-door layout rather than adapted from a coupe.

Engines covered

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

Body styles covered

• 4-door sedan

Trims covered

• Base

Known issues on the 2013 640i Gran Coupe. Coverage begins with the turbocharged inline-six and stays with it a long time: cam timing and chain drive, cylinder head work, the high-pressure fuel side, charge-air and cooling, all with the clearances and tightening values each assembly is measured against. From there it moves outward to the automatic transmission and final drive, the brakes with their hydraulic and anti-lock diagnostics, the steering and suspension with their alignment specifications, and the four-door body's own circuits, drawn end to end.
