2012 BMW 740i Service and Repair Manual

This factory service and repair manual for the 2012 BMW 740i covers a four-door sedan in Base and M Sport form, both powered by the turbocharged 3.0-liter inline-six with double overhead camshafts. Two trims and one drivetrain keep the mechanical chapters common, and the manual spends its length on depth instead of breadth, documenting engine, driveline, chassis, body and electrical systems with procedures, specifications, torque values and the diagnostics used to confirm a repair.

Known issues on the 2012 740i. One recall stands on the federal record, and it concerns the driveline: the constant velocity joint at the rear driveshaft can fatigue and break, leaving the car without drive. Six complaints are logged for the year, two on the seat belts and one each on the engine and the electrical system. Driveshaft and joint service is documented here with the torque values for its fasteners, alongside restraint and belt system procedures, engine repair and the wiring diagrams for tracing an electrical fault.
