Additional Notes

  • The BMW X2 U10 (EU) M135i xDrive PF (221 kW) splits its cooling system into two separate circuits: a high temperature cooling circuit with a capacity of 6.58 liters and a low temperature cooling circuit holding 2.82 liters, bringing the combined total to approximately 9.4 liters.
  • The X2 sDrive18d (110 kW) uses a single unified cooling system with a capacity of 7.6 liters, making no distinction between high and low temperature circuits as seen in other configurations within the same model range.
  • Both the X2 sDrive20d Mild-Hybrid (120 kW) and the xDrive20d Mild-Hybrid (120 kW) share identical cooling system capacities: 7.42 liters for the high temperature circuit and 3.18 liters for the low temperature circuit, despite one being a front-wheel-drive variant and the other an all-wheel-drive variant.
  • The low temperature cooling circuit on the 20d Mild-Hybrid variants, at 3.18 liters, is notably larger than the 2.82-liter low temperature circuit found on the M135i xDrive PF, reflecting differences in thermal management demands between the mild-hybrid drivetrain and the high-performance petrol unit.
  • The X2 xDrive20i PF (150 kW) carries a variable high temperature circuit capacity listed as a range of 8.6 to 9.2 liters. A capacity range of this kind typically indicates that the exact fill volume depends on factors such as the presence of optional equipment or residual fluid retained during a service fill rather than a full system drain.
  • All coolant capacity figures across the X2 U10 (EU) lineup apply under normal use conditions, meaning no separate severe-use or first-change-only interval distinctions are specified for the cooling system.
  • The high temperature circuit of the xDrive20i PF, at 8.6 to 9.2 liters, represents the largest single-circuit coolant volume in the X2 U10 (EU) range, exceeding the 7.42-liter high temperature circuit of the Mild-Hybrid variants and the 6.58-liter circuit of the M135i xDrive PF.
