2020 BMW 440i Service and Repair Manual

This factory service and repair manual for the 2020 BMW 440i keeps to the convertible and the coupe, Base and M Sport, with a single gasoline engine underneath: the 3.0L inline-six, turbocharged, with double overhead camshafts. That consistency is worth something in a workshop, because a specification looked up once is good for either body, and only the roof, glass and body wiring sections require a technician to check which of the two cars is being worked on.

Engines covered

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

Body styles covered

• 2-door coupe

Known issues on the 2020 440i. The manual documents the whole vehicle rather than a set of highlights. The turbocharged six is set out in service procedures and specifications, from fuel and ignition to charge air and cooling. The driveline gets its own overhaul and diagnostic material. Brakes, steering and suspension come with torque values and settings, and the body chapters supply wiring diagrams complete enough to follow a circuit from the fuse box through to the component at fault.
