2020 BMW M240i Service and Repair Manual

This factory service and repair manual for the 2020 BMW M240i lists its trims as Base, Convertible and Coupe, which lines up with the two bodies the car was built in: a two-door convertible and a two-door coupe. One engine serves all of them, a 3.0L inline-six with double overhead camshafts, turbocharged, on gasoline. That arrangement makes the powertrain sections universal and pushes the differences into the body — roof structure, glass, sealing and the circuits that run through them — where each version is treated on its own.

Known issues on the 2020 M240i. The mechanical half of the manual is common to every car here: engine assembly and timing procedures for the turbocharged six with their torque figures, cooling and lubrication specifications, fuel and ignition test values, and the driveline work behind them. Chassis sections give suspension geometry, steering service and brake specifications. The body half divides, covering the folding roof and its mechanism on the convertible and the fixed structure on the coupe, along with climate control, lighting and closure hardware, all supported by wiring diagrams and connector views.
