2007 BMW 550i Service and Repair Manual

This factory service and repair manual for the 2007 BMW 550i is written for a four-door sedan with a 4.8L DOHC V8, naturally aspirated and gasoline-fueled, offered in Base, Formula 1 and Top trims. No forced induction and no alternate displacement means one set of engine numbers throughout. What varies among the three trims is equipment rather than mechanicals, so the specifications carry across while the body and electrical sections capture the differences that matter on a given car.

Known issues on the 2007 550i. This manual's purpose is to replace guesswork with sequence and specification. Engine work is described in the order it has to happen, with the measurements taken along the way and the torque figures closing each step. Fuel delivery, ignition, cooling and emissions each have diagnostic procedures of their own, and the sedan's wiring diagrams show the circuits linking sensors to control units, which is where an intermittent fault on a car with this much equipment is usually found and where a parts-first approach usually fails.
