2011 BMW 120i Service and Repair Manual

This factory service and repair manual for the 2011 BMW 120i treats trim as an equipment question rather than a mechanical one. Base, Dynamic, M Sport and Style all use the same 2.0L inline-four of 122 cubic inches, naturally aspirated, with double overhead camshafts and gasoline injection, and all are available as two-door or four-door hatchbacks. The consequence for a technician is that the mechanical procedures read straight through, while the wiring, interior and body sections are where the four versions have to be told apart.

Known issues on the 2011 120i. Coverage starts at the engine and works outward. The 2.0L four is documented for mechanical overhaul, fuel and ignition service, cooling and emission control, with clearances and torque values throughout. Transmission and driveline procedures follow it, and the chassis sections give brake, steering and suspension service with the alignment and setting data each requires. Wiring diagrams cover both bodies and all four trims, and the diagnostic chapters set out the test steps for the systems those diagrams describe.
