About the BMW XM 50e G09
The BMW XM 50e is the six-cylinder plug-in-hybrid version of the G09 XM. BMW lists its engine as XB1 / B58: a 2,998 cm³ six-cylinder petrol engine working with an electric drive, M xDrive all-wheel drive and the 8-speed M Steptronic Sport with Drivelogic.
This sets it apart from the XM and XM Label, which use the XB1 / S68 drivetrain. A calibration for the 50e is specific to its B58 plug-in-hybrid system, and the engine control unit and hybrid-related software must be identified from the vehicle before any file is prepared.
With an XM 50e enquiry, tell us the build date, delivery market, current software levels and fuel grade. Battery and charging condition and any stored hybrid faults are important, as are aftermarket parts or previous tuning.
