2014 BMW 320i Service and Repair Manual

This factory service and repair manual for the 2014 BMW 320i covers a four-door sedan offered in Base, Luxury, M Sport, Modern and Sport trims, every one of them powered by the turbocharged 2.0-liter inline-four of 122 cubic inches, double overhead cam, on gasoline. It is the busiest year of this run on the federal record, which makes the diagnostic material worth having: the engine management, fuel, brake and restraint sections each carry test values and fault trees rather than general description.

Known issues on the 2014 320i. Seven recalls sit on the federal record. Head air bag inflators can split at a weld joint, either leaking gas so the bag only partly inflates or rupturing and throwing fragments; the vacuum pump that assists the brakes can fail through poor lubrication and leave the pedal hard; and a fuel pump can quit outright and stall the car without warning. Owners have logged 51 complaints, led by the electrical system with nine, the engine with eight and the power train with six, the areas this manual diagnoses in most depth.
