1991 BMW 735i Service and Repair Manual

This factory service and repair manual for the 1991 BMW 735i belongs with the car rather than on a shelf: one four-door sedan body, one trim, one naturally aspirated 3.5L inline-six with a single overhead camshaft and gasoline fueling. Its sections are written to be worked from, giving the sequence of each job, the tightening figure at each fastener, the measurement that decides whether a part is still serviceable, and the wiring detail that turns a suspected circuit fault into a tested one.

Known issues on the 1991 735i. Three recalls sit on the federal record for this model year. A locking tab on the steering wheel contact ring can break, after which the wiring through the ring may fail, the warning lamp lights and the frontal air bag would not deploy in a frontal impact. The brake light switch can stick off or on, leaving the lamps dead or permanently lit. And an unnoticed overheating condition can crack or separate the heater core end piece and release hot coolant. Three complaints are logged, two on engine and engine cooling and one on exterior lighting.
