BMW iX1, U11 (EU)

Automatic transmission fluid capacity & service interval

BMW iX1, U11 (EU) automatic transmission fluid capacity ranges from 0,5 to 2,1 liters. The data covers 2 configurations.

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

TypeSpecifications

  • Electric drive
  • Use: Normal
  • Capacity 0,5-2,1 liter
  • Code: HEAT 220MF, 220LR, 220 XLR 1/1
  • iX1 xDrive30 (2022- )
  • Electric drive
  • Use: Normal
  • Capacity 2,1 liter
  • Code: HEAT 220MF, 220LR, 220 XLR 1/1

Additional Notes

  • The BMW iX1 U11 (EU) uses an e-transmission rather than a conventional hydraulic automatic gearbox, which reflects the electric drivetrain architecture shared across both configurations covered here.
  • The iX1 xDrive30 carries a fixed automatic transmission fluid capacity of 2,1 liters under normal use conditions, indicating a single defined service fill volume with no variable range.
  • The iX1 eDrive20 lists a capacity range of 0,5 to 2,1 liters under normal use conditions, which is notably different from the fixed figure on the xDrive30. A variable range of this kind typically reflects a top-up or partial refill scenario on the lower end, with the upper value representing a full service fill.
  • The 2,1-liter upper bound on the eDrive20 matches the fixed capacity of the xDrive30 exactly, suggesting the maximum fill volume for the e-transmission is consistent across both variants when a full fluid exchange is performed.
  • No service interval mileage or time-based replacement schedule appears in the specifications for either variant, with the data limited strictly to fluid capacity figures under normal use conditions.
