2016 BMW 420i Service and Repair Manual

This factory service and repair manual for the 2016 BMW 420i covers a two-door coupe with a single engine and a single trim: a 2.0L inline-four of 122 cubic inches, turbocharged, with double overhead cams, running on gasoline. There is nothing to disambiguate before starting a job, which is the quiet advantage of a one-specification model year — every clearance, torque value and diagnostic reading printed in the book applies to the car in front of you.

Known issues on the 2016 420i. What the manual provides is procedure and number. Engine mechanical work on the turbocharged four comes with torque sequences and clearances; the induction, fuel, ignition and cooling systems are specified with their own test values; and the transmission and driveline sections give the figures needed for removal and reassembly. Brake, suspension and steering coverage includes the settings a coupe needs after component replacement, and the electrical chapters carry wiring diagrams and diagnostic routines for the lighting, climate, restraint and convenience circuits.
