2015 BMW 328d xDrive Service and Repair Manual

This factory service and repair manual for the 2015 BMW 328d xDrive documents a sedan and a wagon sharing one diesel powertrain: a 122-cubic-inch 2.0L inline-four, turbocharged, with double overhead cams, in a single trim across both bodies. That arrangement means the engine, transmission and driveline chapters are written once, while the body, glass and rear electrical sections split according to which shape is on the lift. Identifying the body first saves tracing a circuit that was never fitted.

Known issues on the 2015 328d xDrive. Twenty-seven complaints are recorded for this model year, weighted toward the fuel system with six, the power train with five and the fuel and propulsion system with five more. Those are the systems where a diesel gives the least warning, and they are also the ones the manual specifies most tightly: fuel delivery and injection procedures with their pressures and tolerances, engine mechanical work with clearances and torque values, and transmission and driveline service with the figures each assembly needs on reassembly.
