With no second engine or body to work around, the procedures, specifications, torque values, wiring diagrams and diagnostics describe one configuration from the crankshaft out to the door modules.

Known issues on the 2021 530i. Eight recalls are recorded federally for this year. One covers rear output shafts that can break because of a heat treatment error, costing drive or letting a parked car roll away. Another concerns the connection between the 48-volt battery and the starter-generator, where poor assembly raises electrical resistance enough to risk a fire. Two more cover an engine starter that can overheat and ignite, one through a corroding relay and one through internal wear. Driveline service, starting and charging diagnostics and the wiring diagrams behind them are all documented here.
