2012 BMW 528i Service and Repair Manual

This factory service and repair manual for the 2012 BMW 528i is written around a turbocharged 2.0L inline-four of 122 cubic inches, a double-overhead-cam gasoline engine, in a four-door sedan sold in Base trim. Forced induction brings service ground of its own — charge-air routing, boost control, and the cooling and lubrication demands that come with it — and the engine chapters carry the specifications and torque values for all of that alongside the standard mechanical, fuel and ignition procedures.

Known issues on the 2012 528i. Four recalls are recorded. Two concern the vacuum pump that supplies brake power assistance, which can fail from insufficient lubrication and leave the driver with far less help at the pedal. Another covers in-tank fuel pump connections crimped too loosely, where wires work free, melt the connector and either leak fuel or stall the engine. The fourth involves a water pump connector sealed poorly enough to admit water and short, with fire the consequence. Owners logged 99 complaints, led by 24 on the engine, 22 on the power train and 14 on fuel and propulsion.
