2015 BMW M235i Service and Repair Manual

This factory service and repair manual for the 2015 BMW M235i has two bodies to account for, a two-door convertible and a two-door coupe, sharing one Base trim and one engine, the turbocharged 3.0L DOHC inline-six on gasoline. The convertible is what widens the book, since its roof mechanism and the circuits that serve it need procedures and diagrams of their own, while the powertrain, driveline and chassis material is common to both cars and given once with the specifications and torque values each system requires.

Engines covered

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

Body styles covered

Known issues on the 2015 M235i. Two recalls are recorded, both on the same failure: the head air bag inflator can fail at a weld joint, letting gas escape so the bag inflates only partially, or bursting and sending sharp fragments through the cabin. Either outcome raises the risk of injury in a crash. Owners have logged five complaints, among them one each on the electrical system, the seat belts and the tires. Restraint diagnostics, belt hardware procedures and the wiring diagrams for this coupe and convertible are all set out in the manual.
