2015 BMW 550i Service and Repair Manual

This factory service and repair manual for the 2015 BMW 550i is written for a four-door sedan in Base, Luxury and M Sport trim, powered by the turbocharged 4.4L DOHC V8 of 268 cubic inches. Displacement, layout and induction are constant across the range, so a specification looked up for one car applies to the others; what changes is the equipment fitted around them. The book runs from engine mechanical work outward, ending in the wiring diagrams for the sedan's electrical circuits.

Known issues on the 2015 550i. Six owner complaints are on record for this model year, the largest group being three on the fuel and propulsion system, followed by two on the power train and one on tires. That is a light record, and the systems behind it are ordinary service ground: fuel delivery and its diagnostics, transmission and driveline procedures with their torque values, and wheel and tire specifications. All three are documented here in the same detail as the engine work, with wiring diagrams for the sensors and controls involved.
