2017 BMW 320i Service and Repair Manual

This factory service and repair manual for the 2017 BMW 320i covers two trims, Base and Sport Line, on one four-door sedan body with one engine, the turbocharged 2.0-liter inline-four of 122 cubic inches, double overhead cam, gasoline. Two specifications is a narrow range, and the practical effect is that the manual can be prescriptive: procedures name the exact sequence and torque, and where the two cars differ, the wiring diagrams and component locations say so directly.
