2019 BMW M240i Service and Repair Manual

This factory service and repair manual for the 2019 BMW M240i is written for a car offered two ways and powered one way. The bodies are a two-door convertible and a two-door coupe; the trims are Base and Sport; the engine, in every case, is a turbocharged 3.0L inline-six with double overhead camshafts running on gasoline. Anything under the hood or under the floor is therefore common ground, and it is in the body, roof and equipment sections that the manual separates one car from the other.

Engines covered

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

Known issues on the 2019 M240i. Coverage begins at the engine and works outward. The inline-six has its timing, valvetrain and oiling procedures with clearances and tightening order, the turbocharger and charge-air circuit have their own tests, and fuel delivery and ignition carry the diagnostic values that separate a fueling fault from a spark fault. Transmission and driveline sections follow, then suspension, steering and brake specifications. The body material covers the convertible's roof mechanism and the coupe's fixed structure, climate control, lighting and closures, each with its wiring diagrams.
