2013 BMW 125i Service and Repair Manual

This factory service and repair manual for the 2013 BMW 125i covers one engine in one body at two levels of equipment: the naturally aspirated 3.0L DOHC inline-six of 183 cubic inches, a two-door coupe shell, and the Base and M Sport trims. The mechanical content is common to both cars, so the differences that do exist — suspension settings, seating, trim hardware and the wiring that serves it — are picked up in the chassis and body sections rather than anywhere in the engine chapters.

Known issues on the 2013 125i. The inline-six sets the pace of most jobs on this car, and the engine chapters carry its timing-chain procedure, valve-gear clearances, cooling and crankcase ventilation service and the torque values each of those steps needs. Transmission and rear-axle work, driveshaft service, suspension overhaul with alignment specifications for both trim levels, steering, brake hydraulics and stability control, restraints, climate control and body electrical fill out the rest, with wiring diagrams and diagnostic trees for tracing a fault instead of guessing at it.
