2007 BMW 120i Service and Repair Manual

This factory service and repair manual for the 2007 BMW 120i adds an M Sport version to the Base, Dynamic and Style cars, all four built on the same pair of hatchback bodies, two-door and four-door. One engine serves them: a 122-cubic-inch 2.0L inline-four, naturally aspirated, DOHC, gasoline. The trims are equipment and specification levels on a shared mechanical package, which is why the engine chapters stay single while the chassis, interior and wiring material carries whatever differences exist between the four.

Known issues on the 2007 120i. What the manual sets out is the whole of the car in service terms. Engine work on the 2.0L four covers mechanical overhaul, fuel injection, ignition and the cooling and emission control equipment attached to them. Transmission, clutch and final drive procedures follow, then brakes, steering and suspension with their specifications and torque values. Wiring diagrams cover both hatchback shells and all four trims, and the diagnostic sections give the fault codes and test steps for the control modules the car carries.
