2020 BMW 745e xDrive Service and Repair Manual

This factory service and repair manual for the 2020 BMW 745e xDrive documents a four-door sedan whose gasoline 3.0L DOHC inline-six is turbocharged and paired with a plug-in hybrid drive, offered in a single Base trim. That combination is the whole of the model on paper, which keeps the service material tightly scoped: every fueling, cooling and charging specification in the engine chapters belongs to this car, with no alternate displacement or second body shell to filter out along the way. The chassis and body sections follow the same single-configuration logic.

Known issues on the 2020 745e xDrive. Anyone servicing this car works around a high-voltage system that stays live until it is deliberately shut down, and the manual treats that as the first step rather than an afterthought. It gives the safety procedure, the wiring diagrams for the traction battery and the charging hardware, and the fault-code tables for the modules that coordinate motor and engine torque. The combustion half is documented separately, with turbocharger and fueling specifications, cooling system procedures and the torque values needed to put the inline-six back together correctly.
