1993 BMW 740i Service and Repair Manual

This factory service and repair manual for the 1993 BMW 740i covers the four-door sedan in Base form with the 4.0-liter V8, double overhead cam, naturally aspirated, gasoline. A V8 in a large sedan of this era means a dense engine bay and long service intervals that eventually come due all at once, and the manual carries what that work needs: cooling and lubrication procedures, valve gear and timing specifications, fuel and ignition diagnostics, and the torque figures for each of them.

Known issues on the 1993 740i. Two recalls sit on the federal record. One covers a brake light switch that can stick, leaving the brake lamps permanently lit or permanently dark, so drivers behind cannot tell when the car is slowing. The other involves a plastic bushing at the throttle housing, shared by the throttle and cruise control cables, which can break and let the outer cable separate so the throttle valve stays partly open. Of the 22 complaints logged, nine name the engine and cooling system, three the seats and two the air bags, all covered here.
