Additional Notes
- The Cupra León KL1 2.0 TDI (110 kW) 4Drive rear differential holds 0.9 liter, a capacity consistent with a standard service fill for a rear axle differential unit.
- Both the 2.0 TFSI (180 kW) and the 2.0 TFSI VZ (221 kW) front axle lock differentials share a capacity range of 0.4–0.6 liter, reflecting the smaller fluid volume typical of a front-mounted locking differential compared to a full rear axle unit.
- The front axle lock differential on the 2.0 TFSI (180 kW) and 2.0 TFSI VZ (221 kW) variants carries a 24-month change interval under normal use conditions, making time the governing factor rather than mileage for those configurations.
- The rear differentials on the 2.0 TFSI VZ (228 kW) 4Drive and the 2.0 TFSI VZ (245 kW) 4Drive both specify a 0.9 liter capacity, matching the figure recorded for the diesel 4Drive variant despite the significant difference in power output between the three engines.
- No change interval is listed for the rear differential on the 2.0 TDI (110 kW) 4Drive, the 2.0 TFSI VZ (228 kW) 4Drive, or the 2.0 TFSI VZ (245 kW) 4Drive under normal use, whereas the front axle lock units on the TFSI variants introduced from 2021 carry an explicit 24-month interval.
- The capacity range of 0.4–0.6 liter for the front axle lock differential, rather than a fixed single value, indicates a fill-to-level procedure where the actual accepted volume depends on the fluid level at the fill plug rather than a precise measured quantity.
