2010 BMW 550i GT Service and Repair Manual

This factory service and repair manual for the 2010 BMW 550i GT covers an unusual shape with a conventional service story underneath it: a four-door hatchback in a single Base trim, carrying a 4.4L turbocharged V8 with double overhead camshafts and gasoline fueling. A boosted V8 concentrates a great deal of heat in one engine bay, and the cooling and lubrication material addresses that directly, with the specifications, torque values, wiring diagrams and diagnostics continuing through the driveline, chassis and body.

Engines covered

• 4.4L V8 — DOHC, turbocharged, gasoline

Body styles covered

• 4-door hatchback

Trims covered

• Base

Known issues on the 2010 550i GT. The jobs that matter on a twin-cam turbocharged V8 are the ones where access is poor and the torque figures are not negotiable: cooling system service and bleeding, oil supply and return at the turbocharger, exhaust and intake hardware, and accessory drive work that has to be reassembled in the right order. The manual prints those values, extends the same treatment to brakes, steering, suspension and driveline, and backs both with wiring diagrams and diagnostic sequences for the car's circuits.
