2015 BMW 228i xDrive Service and Repair Manual

This factory service and repair manual for the 2015 BMW 228i xDrive covers two bodies, a two-door coupe and a two-door convertible, sharing one Base trim and one engine, the turbocharged 2.0L DOHC inline-four of 122 cubic inches running on gasoline. A small forced-induction four works hard, so its cooling, lubrication and charge-air material carries real weight in the engine chapters, while the convertible's roof mechanism and the wiring that serves it add body sections the coupe does not need.

Known issues on the 2015 228i xDrive. Owners have logged 17 complaints against this model year. The largest cluster, five, falls under engine and engine cooling, with two more against the engine itself and two against the electrical system. That grouping puts attention on the turbocharged four and the systems that keep its temperature in check, meaning the coolant circuit, thermostat behavior, fan control and the sensors reporting on all three, and the manual covers them with cooling specifications, component procedures, wiring diagrams and the fault-code routines used to test them.
