2015 BMW M135i Service and Repair Manual

This factory service and repair manual for the 2015 BMW M135i covers both shells the car was listed in — a four-door hatchback and a two-door hatchback — with the turbocharged 3.0L DOHC inline-six and a single Base trim. Mechanically the two are the same machine, so engine, transmission and chassis procedures apply to either. The practical difference falls to the body sections and the wiring diagrams, where a second pair of doors brings its own latch, glass and harness detail.

Engines covered

• 3.0L inline-six — DOHC, turbocharged, gasoline

Known issues on the 2015 M135i. The value here is procedural: torque sequences and clearances for the turbocharged inline-six, boost and fuel pressure specifications, cooling system service, transmission and driveline overhaul, steering and suspension alignment figures, brake system data, and the circuit diagrams and diagnostic trees for the lighting, comfort and safety systems of both hatchback bodies.
