This factory service and repair manual for the 2013 BMW 320i covers the sedan across five trims, Base, Luxury, M Sport, Modern and Sport, all sharing one drivetrain: the turbocharged 2.0-liter double-overhead-cam inline-four of 122 cubic inches. Since the mechanical package does not change with trim, the differences worth chasing are in equipment and wiring, and the electrical sections carry the diagrams and connector views that separate one specification from another when a circuit has to be traced.

Known issues on the 2013 320i. The federal record carries three recalls. Braking accounts for two: the vacuum pump behind the brake booster can seize for want of lubrication, and its lines and fittings can fail in a way that produces the same loss of assistance and a much harder pedal. The third involves side marker lamps that can stay dark, reducing how well the car is seen after dusk. Of the nine complaints on record, two name the air bags, two the power train and one the engine, all systems documented here.
