1999 BMW 740iL Service and Repair Manual

This factory service and repair manual for the 1999 BMW 740iL covers the four-door sedan in Base trim, powered by the naturally aspirated 4.4L DOHC V8. The single-engine, single-body layout keeps the reference work short: one set of engine specifications, one transmission, one chassis. What takes up room instead is the electrical side of a large luxury sedan, and the wiring diagrams run through lighting, climate control, seat and window circuits alongside the engine management harness.
