2019 BMW i3s Service and Repair Manual

This factory service and repair manual for the 2019 BMW i3s reaches across four trims, Base, Range Extender, REX Sport and Sport, all built on the same four-door hatchback body. Two power sources are listed against them: battery-electric drive, and a naturally aspirated 0.6L inline-two with a single overhead camshaft. A technician needs to know which car is on the lift before opening the engine sections, because part of the range has no combustion engine in it at all.

Known issues on the 2019 i3s. What this manual documents falls into three parts. Battery-electric drive gets its own procedures, specifications and fault diagnosis. The small inline-two that comes with the range-extending trims is covered separately, as an engine with its own fuel, ignition and cooling service. Around both, the hatchback's chassis and body sections give brake and suspension procedures, torque values, and wiring diagrams for tracing the lighting, cabin and instrument circuits back to a connector rather than replacing parts on suspicion.
