2020 BMW 440i Gran Coupe Service and Repair Manual

This factory service and repair manual for the 2020 BMW 440i Gran Coupe keeps the same two trims, Base and M Sport, on the four-door hatchback, and the same engine ahead of them: 3.0 liters, inline-six, twin overhead cams, turbocharged, gasoline. What the manual adds to that specification is depth, the clearances, torque figures, pressures and resistances that a service schedule assumes but never prints, together with the procedures in which those numbers are put to use.

Engines covered

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

Body styles covered

• 4-door hatchback

Trims covered

• Base
• M Sport

Known issues on the 2020 440i Gran Coupe. Work on a forced-induction six is largely a matter of measurement, and the book supplies the values: bearing and head torques, timing procedures, boost and fuel pressures, cooling system specifications, sensor resistances. Diagnostics are sequential. Beyond the engine, the transmission and driveline, brakes, suspension, steering and climate control each have their own data, and the electrical diagrams cover the hatchback body across both trims so the drawing can be matched to the equipment in front of you.
