2017 BMW 430i Service and Repair Manual

This factory service and repair manual for the 2017 BMW 430i has the widest spread in this range to account for: three bodies, a two-door coupe, a two-door convertible and a four-door coupe sport line hatchback, and three trims, Base, Gran and Sport Line, all on one engine, the 2.0-liter turbocharged inline-four of 122 cubic inches with double overhead camshafts on gasoline. Mechanically the cars are one vehicle; structurally they are three, and the book is split accordingly.

Known issues on the 2017 430i. Shared ground gets treated once: engine assembly clearances and torque values, charge-air and cooling specifications, fuel and ignition diagnostics, transmission and driveline procedures, and brake, steering and suspension data. The divergence sits in the body sections, where the convertible's roof mechanism, drive and seals, the coupe's fixed structure, and the hatchback's rear opening and latching each have their own procedures, and where the wiring diagrams follow harnesses that must run through three different shells.
