2012 BMW 550i GT Service and Repair Manual

This factory service and repair manual for the 2012 BMW 550i GT is defined by one trim and one engine: Base, and a turbocharged 4.4L V8 with double overhead camshafts running on gasoline, in a four-door hatchback body. Because there is no alternate powertrain to allow for, the engine material stays with this V8 and its fuel, ignition, cooling and lubrication systems, and the specifications, torque values, wiring diagrams and diagnostics carry forward into the driveline, chassis and body sections without qualification.
