BMW XM, G09 (EU)

Coolant capacity & service interval

BMW XM, G09 (EU) models utilize coolant with capacities ranging from 5,6 to 16,1 liters. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
XM 50e Plug-in Hybrid xDrive PF (353 kW) (2024- )
  • Use: Normal
  • Capacity 15,4-16,1 liter (High temperature cooling circuit )
  • Capacity 6,6-6,9 liter (Low temperature cooling circuit)
XM Label Red xDrive PF (550 kW) (2023- )
  • Use: Normal
  • Capacity 12 liter (High temperature cooling circuit )
  • Capacity 5,6 liter (Low temperature cooling circuit)

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.
