Additional Notes
- The Volkswagen Jetta, GLI, BU4 manual transaxle specifications list two distinct engine configurations for the 2021 model year: the 1.5 FSI rated at 118 kW and the 2.0 TFSI rated at 170 kW.
- Both configurations share an initial fill capacity of 2.3 liters, which represents the total fluid volume required when the transaxle is completely dry, such as after a full overhaul or unit replacement.
- The service fill capacity differs between the two engines. The 1.5 FSI carries a service fill of 2.1 liters, while the 2.0 TFSI carries 2.15 liters, reflecting the slightly different internal volumes that remain accessible during a standard drain-and-refill procedure.
- The 0.05-liter difference in service fill between the 1.5 FSI and the 2.0 TFSI is a small but specification-defined distinction, meaning the two transaxles are not interchangeable in terms of fluid quantity during routine servicing.
- Both engine variants share an identical check interval of 20,000 miles or 24 months under normal use conditions, whichever comes first.
- The interval is designated for normal use conditions only, meaning the 20,000-mile or 24-month check schedule applies specifically to that operating context as defined in the specifications for both configurations.
