1994 BMW 740iL Service and Repair Manual

This factory service and repair manual for the 1994 BMW 740iL is written around one engine, one body and one trim — the naturally aspirated 4.0L DOHC V8 on gasoline, a four-door sedan, in Base form. Rather than sorting between variants, a technician works straight through by system: engine mechanical and cooling, fuel and ignition, the automatic transmission and final drive, then steering, brakes and suspension, and finally body and interior electrics with the wiring diagrams that go with them.

Known issues on the 1994 740iL. The federal record holds one recall, for a brake light switch that can fail internally and lock in either position — brake lamps that never come on, or lamps that never go out, in both cases hiding what the pedal is doing from following traffic. Complaints number four: three about the engine and cooling system and one about the electrical system. Cooling circuit diagnostics, engine specifications and the switch and lamp circuits are each set out in the relevant sections.
