2020 BMW 118i Service and Repair Manual

This factory service and repair manual for the 2020 BMW 118i narrows to a single configuration: one four-door hatchback body, one M Sport trim and one engine, the 1.5-liter turbocharged inline-three with double overhead camshafts on gasoline. That leaves no cross-referencing to do — every clearance, torque value, fluid specification and wiring diagram in it belongs to the car in front of the technician, including the firmer suspension settings and the wheel and brake data that come with M Sport equipment.

Known issues on the 2020 118i. The manual covers the three-cylinder engine in full — mechanical clearances, timing drive, turbocharger and charge-air service, boost control and fuel pressure testing, cooling and lubrication specifications — then moves through the transmission and final drive, brake hydraulics, suspension and steering torque values and alignment settings, and the wiring diagrams for lighting, locking, climate and instrument circuits, each paired with its diagnostic sequence.
