2022 BMW 745e Service and Repair Manual

This factory service and repair manual for the 2022 BMW 745e is written to a narrow specification: one body, one trim, one powertrain. The car is a four-door sedan in Base form, moved by a 3.0L DOHC inline-six that is turbocharged, gasoline-fueled and tied into a plug-in hybrid drive. Because no second engine and no second body have to be accounted for, the specifications and torque values printed in the engine chapters apply directly to the car on the lift, and the wiring diagrams describe a single electrical architecture rather than a family of them.

Engines covered

• 3.0L inline-six plug-in hybrid — DOHC, turbocharged, gasoline

Body styles covered

• 4-door sedan

Trims covered

• Base

Known issues on the 2022 745e. A plug-in hybrid puts two control systems in charge of one driveline, so diagnosis usually starts by deciding which side of the car is at fault before any part comes off. The manual supports that with fault-code routines and wiring diagrams for the hybrid control modules, the traction battery and the charging hardware, alongside the fueling, ignition and cooling diagnostics for the turbocharged inline-six. Brake, suspension, steering and body electrical sections carry their own specifications and torque values in the same format.
