2012 BMW X3 Service and Repair Manual

Every trim listed for the 2012 BMW X3 wears an xDrive badge, and this factory service and repair manual covers the six of them — xDrive28i through xDrive35i M Sport — on two engines: a turbocharged 3.0L inline-six and a naturally aspirated 3.0L inline-six of 183 cubic inches, both double-overhead-cam gasoline units, in a four-door sport utility. Same displacement, different induction, so the manual keeps their fuel, cooling and diagnostic material distinct even where the mechanical work overlaps.

Known issues on the 2012 X3. Since all six trims drive all four wheels, the transfer case, propshaft and final drive procedures apply to every vehicle covered, and they are given with the torque values and service limits that driveline work demands. Engine coverage runs separately for the turbocharged and naturally aspirated sixes. Suspension, steering and brake sections carry their own specifications, and the electrical chapters supply wiring diagrams and diagnostic sequences across the range, which is what a technician needs when a fault crosses between the powertrain and the body network.
