2020 BMW 745Le xDrive Service and Repair Manual

This factory service and repair manual for the 2020 BMW 745Le xDrive has two power sources to document in one car: a turbocharged 3.0L DOHC inline-six on gasoline working within a plug-in hybrid drive, all-wheel drive, in a Base-trim four-door sedan. Six cylinders and a high-voltage system in the same car make for a long engine section and an equally serious hybrid section, and both are given as procedures with their specifications, torque values, wiring diagrams and diagnostic sequences rather than as description.

Known issues on the 2020 745Le xDrive. The inline-six is documented system by system: valvetrain and timing drive, the lubrication and cooling circuits, the turbocharger and the charge-air path, fuel supply and the emissions hardware, with clearances and tightening figures given where they are used. The hybrid chapters add high-voltage isolation and de-energizing procedures, battery and charging system service, and their own diagnostics. The driveline, brakes, steering, suspension and body electrical systems follow, the last documented circuit by circuit in wiring diagrams.
