Additional Notes
- The BMW XM G09 (EU) cooling system is split into two separate circuits: a high temperature circuit serving the combustion engine and a low temperature circuit dedicated to the hybrid drivetrain components, including power electronics and the electric motor.
- The XM 50e Plug-in Hybrid xDrive PF (353 kW) carries a high temperature circuit capacity of 15.4–16.1 liters, reflecting a range rather than a fixed value, which is typical when fill levels vary depending on whether air pockets remain in the system after a service fill.
- The low temperature cooling circuit on the XM 50e Plug-in Hybrid xDrive PF (353 kW) holds 6.6–6.9 liters, again expressed as a range consistent with a service fill specification rather than a dry or overhaul fill.
- The XM Label Red xDrive PF (550 kW) specifies a high temperature circuit capacity of exactly 12 liters, a fixed value that contrasts with the range format used for the 353 kW variant.
- The low temperature circuit on the XM Label Red xDrive PF (550 kW) holds 5.6 liters, which is notably smaller than the 6.6–6.9 liter range of the lower-output 353 kW model despite the Label Red producing significantly more power.
- Both configurations are listed under normal use conditions, meaning the capacities and service parameters apply to standard operating environments rather than severe or extended-duty cycles.
- Neither configuration carries a defined service interval in the specifications, meaning the listed data covers capacity values only, with no mileage or time-based coolant replacement interval recorded for either variant.
