2004 BMW 745Li Service and Repair Manual

This factory service and repair manual for the 2004 BMW 745Li covers a four-door sedan built in one trim around a 4.4L V8 with double overhead camshafts, naturally aspirated and gasoline-fueled. The engine list is short but the car is not simple, and the manual is scaled to it, with procedures, specifications, torque values, wiring diagrams and diagnostics for the V8, the driveline, the chassis, and a body whose circuits run the length of the sedan.

Known issues on the 2004 745Li. Work on a car of this size usually starts with a measurement rather than a part, and this manual supplies them. The V8 is documented with its clearances, fuel and ignition data, cooling capacities and torque values. Driveline service has its own procedures. The chassis sections give brake, steering and suspension specifications, and the wiring diagrams cover the sedan's circuits in enough detail to test a connection instead of replacing the component behind it.
