2016 BMW 120i Service and Repair Manual

This factory service and repair manual for the 2016 BMW 120i is built around a turbocharged 1.6L inline-four of 98 cubic inches, a twin-cam gasoline engine that leans on forced induction rather than displacement. Two hatchback bodies are covered, two-door and four-door, in four trims: Base, M Sport, Sport Line and Urban Line. Turbocharging puts charge-air routing, boost control and thermal management into the engine chapters alongside the fuel, ignition and cooling procedures, and the specifications reflect the pressures involved.
