Seat Mii, KF1 (EU)

Automatic transmission fluid capacity & service interval

Seat Mii, KF1 (EU) automatic transmission fluid capacity is 1,1-1,3 liters. Service intervals consist of checks every 12 months or 30000 km. The data covers 2 configurations.

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

TypeSpecifications

Mii 1.0 (55 kW) (2011-2019)
  • Use: Normal
  • Capacity 1,1-1,3 liter

  • Code: 0CT (SQ100) 5/1

Additional Notes

  • Both the Mii 1.0 (44 kW) and the Mii 1.0 (55 kW) share an identical ATF capacity range of 1.1–1.3 liters, which is consistent with a compact transaxle semi-automatic unit rather than a conventional stepped automatic gearbox.
  • The 1.1–1.3 liter figure represents a service fill range rather than a total overhaul capacity, meaning the actual volume accepted during a fluid top-up or partial drain will fall somewhere within that window depending on the residual fluid level at the time of service.
  • Under normal use conditions, the specified check interval for both configurations is 12 months or 30,000 km, whichever comes first, indicating a time-and-distance dual-trigger schedule rather than a mileage-only approach.
  • The Seat Mii KF1 1.0 (44 kW) covers the 2011–2020 model years, while the 1.0 (55 kW) variant spans 2011–2019, meaning the two engine outputs share the same ATF specifications despite differing in their production periods.
