2022 BMW M440i xDrive Service and Repair Manual

This factory service and repair manual for the 2022 BMW M440i xDrive documents one engine across two bodies: a 3.0-liter inline-six mild hybrid, double overhead camshafts, turbocharged, gasoline, fitted to a two-door convertible and a two-door coupe in Base trim. Under the hood the two cars are identical, which is why the engine, cooling and fuel chapters are written once and apply to both, while the structural and trim procedures separate into the sections that describe each shell.

Known issues on the 2022 M440i xDrive. A turbocharged six asks for accuracy in the cooling and charge-air systems, and the manual gives it: coolant circuit routing and thermostat specifications, radiator and charge-air cooler removal, hose and clamp torque values, and the sensor circuits that report temperature and pressure to the engine controller. Emissions coverage follows the same path out through the oxygen sensors and their heater circuits. Stored fault codes are matched to test procedures rather than left as a list to interpret.
