1993 BMW 740iL Service and Repair Manual

This factory service and repair manual for the 1993 BMW 740iL covers a single configuration: a naturally aspirated 4.0L DOHC V8 burning gasoline, a four-door sedan body, and a Base trim. That narrowness is useful on the bench, because every torque value, clearance and diagnostic step in the book belongs to this one car. Engine and cooling, transmission and driveline, brakes, suspension, and the wiring diagrams for the sedan's body systems all describe one specification rather than a family of them.

Engines covered

• 4.0L V8 — DOHC, naturally aspirated, gasoline

Body styles covered

• 4-door sedan

Trims covered

• Base

Known issues on the 1993 740iL. One recall is on the federal record: the brake light switch can fail and stick, leaving the brake lamps either dead or lit constantly no matter where the pedal is, so drivers behind cannot tell when the car is slowing. Nine complaints have been logged, four of them about the engine and cooling system, two about the power train and one about vehicle speed control. Switch testing, brake system procedures, cooling diagnostics and transmission specifications all cover the same ground.
