1991 BMW 735iL Service and Repair Manual

This factory service and repair manual for the 1991 BMW 735iL covers the sedan in its single Base form, with the 3.5L inline-six, one camshaft overhead, naturally aspirated and gasoline-fueled, as the only engine. The manual's value on a car of this age lies in its completeness: torque values and clearances for engine and driveline work, dimensions and settings for the brakes, steering and suspension, and wiring diagrams detailed enough to trace the sedan's many circuits back to fuse, relay and ground.

Known issues on the 1991 735iL. Two recalls stand on the federal record for the 1991 735iL. In one, a locking tab in the steering wheel assembly can break, letting the contact ring wiring fail so the warning lamp lights and the front air bag does not deploy in a frontal crash. In the other, a brake light switch can stick, leaving the brake lamps permanently off or permanently on so following drivers cannot tell the car is stopping. The single owner complaint recorded concerns exterior lighting. Steering column, restraint and lighting circuits are all covered here with diagrams and test steps.
