Additional Notes

  • The Seat León 1M carries a 3-liter automatic transaxle fluid capacity across both the 1.6 16V (2001-2006) and 1.8 20V (1999-2005) engine variants, indicating a service fill rather than a full overhaul quantity.
  • The 2.0 TFSI (2005-2006) holds a notably larger 5.9-liter automatic transaxle capacity, nearly double that of the 1.6 16V and 1.8 20V configurations.
  • A 5.9-liter service fill is consistent with a larger or more complex automatic transaxle assembly, which typically retains more fluid in its torque converter and hydraulic circuit during a partial drain-and-fill procedure.
  • The 1.6 16V and 1.8 20V share an identical 60,000 km check interval under normal use conditions, pointing to a common service schedule across those two engine families.
  • The 2.0 TFSI introduces a dual-condition check interval of 48 months or 60,000 km under normal use, whichever comes first, adding a time-based threshold absent from the other two variants.
  • The 48-month time limit on the 2.0 TFSI means fluid condition is evaluated on a calendar basis regardless of mileage accumulation, which is relevant for vehicles driven infrequently.
  • All three configurations are classified as normal use, meaning the stated intervals apply to standard operating conditions rather than severe or demanding duty cycles.
  • The 1.8 20V covers the widest model year span of the three, running from 1999-2005, and shares the same 3-liter capacity and 60,000 km interval as the later 1.6 16V despite the difference in engine displacement.
